Sennheiser RS 120 II
Like others mentioned. Same experience here — the tuning dial is a constant annoyance. Mine died around the same time too. Ended up returning them and going with a different brand, Simolio. Not worth the price imo.
Highly disappointing to say the least. I wanted to replace my aging Bose units and decided to get the Momentum 4's because a friend recommended… Read more
them. I regret it.
The battery life of these is impressive, but that's where the exciting stuff ends.
I bought these to listen to YouTube and it sounds dreadful, Its distorted, tears and low quality, I googled it and tried a few settings changes which seemed to help... But not for long. It would always return. The bluetooth needs to be constantly re-paired to my devices, if I put my headphones down and walk away for 3 minutes and return then I can't get the things to work right again. I will end up having to un-pair them and start all over again, they are frustrating and simply not worth the $500 price tag. I will persevere with them because I don't want to blow anymore of my money on junk but I will never return to Sennheiser after these ones are done. Save yourself the time and money and just buy something else. Sony or Bose in future.

Quality poor – The three lugs on the ear pads that latch onto to main body are flimsy and break off. Reception when moving about loses the signal at times.
Amazing value for money – These are a real bargain for how they sound. There’s a lot of bass, but it’s super deep. Mids can have so-so quality to them sometimes, but overall a great value.
This product is by far the worst bluetooth product I've ever had to use. Firstly, it's incredibly difficult to get one pair of headphones to pair… Read more
with it. Multiple tries before anything actually happens. Then trying to get a second pair to connect is almost impossible. The fact you have one button that you press for various lengths of time does not help. If you do get a second pair connected and working, it disconnects for no apparent reason randomly. It also disconnects AND FORGETS the headphones if you turn them off, or charge them. It feels cheap and light and nasty and as if it cost probably $2 to build. The fact they charge over $100 for this is unbelievable. Do not buy this product!

started to then behave strangely and switch off after onlu a few minutes of use or randomly do other things, like change tracks.
I initially thought I was touching a button or had forgotten to charge the them but that wasn't the case. It appears that it is a know issue and common occurance which some users online are attributing to using quick chargers or smart chargers with the headphones.
This ofcourse is not something covered anywhere I have found in Sennheisers documentation and most of us would just use what ever USB charger is available with a free port. Also Smart / quick chargers negotiate with the device before changing the voltage level so it is a strange that this could be the issue.
But as I have been reading the forums and discussions on the internet around this issue I see many users are reporting that even the replacement units fail the same way and getting support is not made easy.
So I am going to avoid Sennheiser headphones moving forward due to this. I would recommend also before any purchase of devices near or in this price bracket that you Google for "issues" or "common faults" or "failures" and spend 30 minutes to an hour reviewing what other users are reporting. If you see a trend across multiple forums and discussions describing the same issue / failure then look for alternative product options and search what they have issues with.
If the warranty process was easier and if the other users hadn't reported all the issues they had with the replacement units I would of been going down the warranty support process but at this stage it appears that I have a lemon 10 days after 1year of use.

the wireless headphones, and whenever I want to go to the bathroom downstairs while wearing the headphones, it sounds like I got a home theatre stereo system with me anywhere in the 2-storey rented house. I don't use the app, I just simply increase the volume that gives a balanced treble and bass sound without that earthquake-like rumble shaking noise. It's no wonder the portable CD I had for several years has become old technology because Bluetooth technology gives you freedom to roam the house without cables. A friend bought the headphones as a gift to me
Too expensive for what it does – It's $500 au on sale $350 after using it I would say it worth not more than $130 music sound is average, at high volume sound quality drops… Read more
massively, talking sound is horrible, people have difficulty hearing me and there are constant disconnection Bluetooth is an serious issue with it ,overall I would say $130 would be reasonable but original price is way to high for this product
Waste of money for me! – I do not like these earphones, the pads fell off within a few weeks of buying them, they do not stay in your ears, even when walking, they are sore.… Read more
The sound is ok I guess, but hard to hear anything when they keep falling out your ears. Cheap and cheerful earphones have always done me well in the past, but do not recommend these.
Bought these in 2019 or 2020 to deal with a noisy work environment (ie loud co-workers) and used them consistently every work day over five years. In… Read more
that time I replaced the ear pads ( bought from amazon ) that fell apart and I'm surprised to see that they are still for sale. I'm currently using wireless earbuds as I have changed jobs to an 'agile' work environment but some days are really noisy so I'm considering bringing them in again on those days. I've been really happy with them and had no issues with using them for phone calls. I bought them because the sound quality and noise blocking on my wired earbuds from Sennheiser was exceptional. I found these also good although there is a big difference in listening to a proper music file to something transmitted over the internet. The music quality is better than my current earbuds wireless Soundcore Liberty 4 NC which I also really like. My issues would be you are limited in what earrings you can wear with the headphones because it can become uncomfortable so you are limited to small hoops or studs but then again that is a small fashion sacrifice to pay for peace and quiet.
You don't get what you pay for – Purchased these for $1800 and have not been very impressed with their comfort. Are they comfortable? I guess to some extent they are not… Read more
uncomfortable, but I assumed it would be built a bit better for the price tag. I feel like a lot of big name brands make very expenisve top of the line models to sucker in people like me that just want the best experience.

warranty. Its always the same problem one of the ear buds won't charge its been both left & right not charging each time its a different bud, I went out and bought a bose pair also as I just cant trust that they will work on any given day and at least I have a backup for my long train trips. Its a real shame as they do have quailty sound however once they are dead and my warranty runs out I will not be buying another Sennhesier anything!
Fantastic bang for buck (by adding a few things) – The Sennheiser IE 200 is a wired in-ear bud. It is categorised as an audiophile headphone by Sennheiser and it holds true to that description. For… Read more
$179 (reduced from $239) it is a phenomenal high-fidelity performer for the price. The sound separation and clarity is really noticeable. I have used $1000 triple-driver moulded ear pieces for the past two years and these ear-buds, to my ears, are just as good.
Now.... here's the catch, I did cheat a little to improve the sound. Out of the box and plugged into your phone they are OK.... but if you *really* want to hear their capability you need to connect them to a decent digital to analog converter (DAC). The DAC plugs into the USB-C interface on your phone and there is a 3.5mm jack to connect the ear-buds.
I recommend using the IBASSO DC05 (the photos shows DC03 but DC05 is the current model), for around $80 it will totally make the sound pop through the ear buds.
The second improvement is to use a quality set of silicon ear-tip rather than the ones that comes with the buds. I used the Spinfit W1 for around $30 from Amazon.
The bass, mid-range and highs come through as if you are wearing over the ear headphones. So, by spending another $100 for the DAC and ear-tips you'll get a really great performing pair of ear buds.
Back Story: Having been a fan of the Sennheiser HD 650, as part of my wired headphone collection, I have been avidly reading and watching reviews of… Read more
Sennheiser’s most recent release, the HDB 630 wireless headphones.
Reviews have been mixed, with some saying the overall sound is fairly flat and dull compared to the lively Sennheiser Momentum 4. Others have said it is a masterpiece of engineering, with the ability to be EQ’d to the same spec as a Momentum 4, if that is your preference.
Me, I prefer to put them on my head, EQ them and work it out from there and that’s what this review is about.
A Shout Out to JB Hi-Fi Ringwood:
These are currently retailing for $999.00 AUD. So, with a little bit of Internet research and a couple of gift vouchers, the lovely staff at JB Hi-Fi in Ringwood managed to reduce the price to just over $700.00.
It pays to do your research and find another Australian based retailer, so you can price match.
Unboxing:
Well, this is a bit of a masterclass in how you should get your headphones (apart from a silk-lined wooden box!).
The headphones come packed in their hard-shell case, complete with accessories:
• Airplane 2-prong cable adapter
• Bluetooth dongle (for higher res throughput)
• RCA cable
• Guide booklet
• USB charging cable
The case has a velvet lining, to keep everything protected.
Sennheiser HDB 630 Looks and build:
These are ‘closed-back’ headphones, as opposed to ‘open-back’, which are generally known to keep the sound more internalised within the earcups.
The overall aesthetic of these headphones is understated class, with satin looking black coloured earcups, black leather headband and a silver coloured brushed/textured aluminium cup swivel hinge and lower headband arm.
The earpads are black coloured luxuriously soft leatherette, with each cup labelled ‘L’ and ‘R’, with the right cup lettering stating ‘42MM DYNAMIC DRIVER, FROM IRELAND’. The left cup lettering says ‘SENNHEISER, HDB 630’.
The headphones are relatively light, weighing in at 311g (without cable).
Adjusting the arms to your head is a silent and smooth affair, whereas other brands choose a ratchet system, with numbered markings on the metal arm. This is more sophisticated, where you make the adjustment and the arms are simply held firmly in place.
Buttons:
There is only one button, on the bottom of the right earcup, for on / off.
When putting the HDB 630’s on, I found the earcups to be a tight fit, in comparison to the Soundpeats Cove Pro. I found myself jiggling a fair bit with the left cup, trying to get the right position inside the earpad.
Once fitted, the ear seal is excellent but interestingly, they don’t feel at ultimately comfortable as the Soundpeats Cove Pro or the Bose QC Ultra Gen 2, as the clamp force of the HDB 630’s is noticeably greater. The Cove Pro and Bose QC Ultra Gen 2 earpad hole is a tiny bit bigger and the clamp force doesn’t feel it is even there when you have them on your head. The Cove Pro is a real contender with a Bose headphone in fit and comfort.
The new Bose Ultra second gen also has a similar build to the Cove Pro and is instantly comfortable, with just slightly more room inside the earcups.
Setting up:
When you turn the HDB 630’s on, it apparently measures your ears (inner ear) for the best ANC and sound experience.
The internal voice tells you they are on and you then go to your phones Bluetooth settings and find the Sennheiser HDB 630 in the device list.
Once you have paired the headphones to your phone, as I did with my Galaxy S25 Ultra, I then used the Sennheiser Smart Control app to find the headphones and then continue to set up the headphones via EQ.
Note: at this point I tested the ANC settings: Noise Cancelling, Normal and Transparent.
Nosie cancelling added about another 5% noise cancelling, blocking out a little more of the music from my computer, comparable to Bose standard.
I set the headphones to my go to settings: ‘Noise Control: Custom ANC at 100%, Crossfeed: High, Anti-wind: on and set the graphic or parametric EQ to taste for the best possible resolution and best ANC.
Soft Touch Controls - Right Earcup:
With a few hours of practice, you can easily navigate the touch controls on the right earcup touch pad:
• 1-tap for stop start music
• 2-taps for transparency mode with no music and then again to return to music with ANC
• Swipe forward-back to move the track forwards / backwards
• Swipe up/down for volume
• Call Control:
o Swipe forward to answer call
o Swipe back to end call
o Hold 1-finger for 2-seconds to stop call
o Tap 1-finger twice to answer call
o Tap finger twice to switch between 2 calls
o Press the button near the earcup hinge to mute or unmute the call
o 2-fingers stretch outwards (at the same time) for adaptive noise cancellation
o 2-fingers stretch inwards (at the same time) for transparency mode
• Press the upper button near the hinge once for voice assistant
Sound test:
At 50% volume on my Samsung S25 Ultra and using Spotify lossless and Tidal, I played a variety of tracks.
Due to the excellent ANC, background is black and assists immensely in hearing the frequency range of the tracks.
Jazz tracks just simply pop, with trumpet well separated from drums and bass.
Electronic tracks are punchy and fully enveloping. The sub-bass the often wells up in these tracks is visceral and grabs you in your stomach, as much as an audio experience, as one you can feel.
Soundstage on some tracks like Hotel California – Live is sublime, with the slow drum beat really catching you and the Spanish style guitar weaving in and out.
Lionel Richie is well separated from the instruments in the All Night Long track.
The sheer body to Sara K’s track, All Your Love is compelling. Her vocals are so well rendered and are a contrast to the acoustic guitars.
Watermelon Man by Herbie Hancock is an audio experience, with the calling bird sounds at the start of the track.
The guitars at the start of Grown Folks by Snarky Puppy are so well rounded in space, you can grab each note as it is strummed.
Unfinished Symphony by Massive Attack delivers the gravity of that sub-bass, rendering it so well from the vocals. All throughout the track the bass has a shimmering-reverberation effect. This caught my attention, as I typed these words that I had to stop and listen.
Outside Ambient Street Test:
Walking the dogs on the footpath by the road and then into the park is a real experience. The ANC is so good, you barely hear anything outside the earcups, the envelope is about 99%, with occasional noise filtering in.
There was appoint where I was looking down and didn’t hear a large SUV approach me until I saw the shape of the car right next to me. The entire sound from the vehicle was blocked completely.
In my office I ran a YouTube Airplane white noise video quite loud, on my PC 7.2 surround sound Denon amplifier. I could not hear the plane sound at all except when you stopped playing music. You could hear it, as if it was coming from a long distance away.
I then played a restaurant ambience YouTube video. Again, no sound filtered in, and only filtered in from a distance, when you stopped playing music through the headphones.
Sitting next to a room fan (moving fan head test): I could not hear anything.
Call tests:
I recorded the following via calling myself on my own phone and listening to the calls on my message bank.
• Caller’s voice: Good but sounded a bit electronic.
• In Office: Excellent.
• Fan-Wind: Can hear a bit of wind noise.
• Plane sound via PC (YouTube): Can hear a slight rushing sound.
• Restaurant sound via PC (YouTube): Can hear a slightly garbled background sound.
Interestingly: the call tests on the Sennheiser HDB 630 did not do anywhere as well as the sub $70.00 AUD Soundpeats Cove Pro. Considering the HDB 630 is more than ten times the price, it is a good demonstration of how companies implement their technology differently.
Train travel:
I will be travelling by train again, in the next few weeks so this review will receive an update regarding how well these headphones do with blocking out the noise of the announcements from the train cars and the general ambient sound of the people on the train and the train wheels rolling on the tracks.
Battery Test:
For real world use I would only use the settings I mentioned for maximum sound quality:
Sennheiser indicates battery life with Bluetooth and ANC on is up to 60 hours. In my book, that is nearly five weeks of train journeys for work.
Thoughts:
For sound, I would give an A+++. Excellent sound quality combined with excellent ANC brings out the overall sonic range of these headphones. It also assists with soundstage and tonal balance.
For comfort and fit, I would give an A ++ (almost as good as the Soundpeats Cove Pro and the Bose QC Ultra 2). I think it is because of the weight difference:
• Sennheiser HDB 630 is 311g
• Bose QC Ultra 2 is 263-265g
• Soundpeats Cove Pro is 250g
For the ability to EQ: A+++. This works as good as most of the current proprietary company apps.
If I were to sum up the sound signature: a high-end hi-fi type of sound signature, with the ability to play all genres. The app has the ability to EQ the sound signature to taste, and you can save your EQs in the app.
Last Word:
For the price point of RRP $999.00 AUD, you absolutely get top tier sound, build, comfort and ANC. I strongly suggest like me, you do a bit of research and get a better price match.
As it compares to the Bose QC Ultra 2, another top tier example: the Sennheiser is only really separated by:
• The Sennheiser being heavier, about 45 grams.
• The Sennheiser uses touch controls on the flat of the earcup, which I really like and find really useable.
• The Sennheiser earcup pads are slightly smaller / tighter fitting (which I finally fixed by the time I finished this review, by stretching them out a bit).
These could be your final headphones, for home, work and travel. It can do it all.
The software app is excellent and very usable, from initial setup to fine tweaking.
If I were to score the Sennheiser out of 100, I would give it 99.
The ANC, like with the Bose is almost 100% perfect, but occasionally some noise outside just gets in. Yes, it is that good that I have to get that picky!
The weight, comfort and fit are comparable, with a little bit of adjusting (but you can feel the weight difference when you A and B test the Bose and the Sennheiser directly, one after the other).
The only difference regarding my first impressions when I put on the Sennheiser HDB 630, was that I said, ‘Wow!’, whereas when I put on the Bose QC Ultra Gen 2, I said, ‘OMG!’
I think I was expecting the Sennheiser’s to sound more ‘hi-fi’ like – like a good set of high-end speakers but I didn’t think the Bose were going to be as comparable, so I was a bit more surprised, as the Bose QC Ultra Gen 2 is a massive leap forward from my Bose QC 25’s, which I have travelled with, on off planes and was my ‘daily driver’ for train trips to work and back.
This has been another Ant review, the second for 2026.
I hope you have enjoyed reading it, as much as I have had in compiling it.

purchased a premium headphone for my wife's birthday costing $999 the HDB 630. We discovered that the headphone that comes with a USB-C Bluetooth adaptor BTD 700 does not come with the USB-C to USB-A adaptor that is included when the BTD 700 is purchased separately. As my wife has a n older laptop it only has USB-A ports and so i reached out to Sennheiser, explaining the situation and asked if they could supply the adaptor as it normally comes with the BTD 700. There response was you should have read the manual that comes with the headphones as it shows you only get the USB-A adaptor if you buy the BTD 700 separately. They then sent me a web link to the BTD 700 which costs $69.99. This kind of adaptor costs a few dollars only but Sennheiser wants me to pay for a new adaptor at $70 rather that either offer me a free USB-A adaptor or sell me one which I'd happily so. They offered no alternative and were very unhelpful. My wife at this time cannot use the laptop and headphones together until i manage to sort a quality adaptor. Such a shame, you pay $999 for headphones, and then Sennheiser won't include the appropriate adaptor to connect to USB-A which so many of us out there still use. Avoid this company.

However the ear pads lasted less than 18 months. Bought a replacement set and it was extremely difficult to replace I have never got anywhere near the purported battery life and I am not using the noise cancellation feature.

I can highly recommend the Sennheiser Brand. The products are top quality. I bought the wireless in-ear headphones and wow the sound is excellent. You may pay a bit more but its well worth it.

Not Fantastic But Fair – I recently bought Sennheiser XSW2-835-A Wireless Handheld Microphone for a place of worship. I had big expectation about Sennheiser products because… Read more
this is a big brand. However installation of it to the sound system gave me a bit of trouble. First of all, the sound did not seem to be very crisp as I had expected, but was similar to the cheaper microphone that the place of worship already had. Secondly, as soon as the switch on the microphone was turned off, there came very loud noise from the loudspeakers. There was no instruction in the operating manual how to resolve such issues. I had to resort to Google search to find a solution to this issue. The issue was resolved by finding answers from Google search. It seems to me that this is likely to be common issue with Sennheiser's wireless microphone systems. Sennheiser should have provided solutions to such issues in a troubleshooting documentation in the operating manual.
The on/off switch in the microphone is too small and inconveniently located in a cavity on the microphone which is another 'cons' of it. Finally, the operating manual is poor as it does not contain a description of how to change frequencies in the receiver and synchronize that with the transmitter.
Because of all these issues, I would give it only two stars. I hope Sennheiser people read my review and improve.
