Bad build quality for padding on headphones - started falling apart well before a year was up. Contacted JBL for support no offer of replacement earpad but a place to buy them - its almost $100 to get replacement earpads. Bluetooth connection failed before a year was up

The comfort is great, but the noise cancelling doesn't work as I kept hearing it turn off on its own with the song of a painful popping sound, the bass just was terrible as I have to restart these about 4-5 times to have decent bass. The build quality is great which is why I gave this a 1 star.

I have been using them for a few monthss now, they are comforable and have noise cancelling, but the folding mechanism didn't work as well as I thought it would still great tho. another inconvinience would be that the headphones were slighty bulky

Had these for less than a year and they're completely useless due the folding mechanism on both sides of the headphones failing. Near on impossible to fix and it wouldn't be worthwhile doing cost-wise.
It's a shame because the sound quality is excellent and noise cancelling is tops. Dissapointing.

the duet headphones were redeemed as part of a samsung offer in November 2018, not used until January. By late August only 1 ear was working so sent back to JBL who replaced them a few weeks later. In mid december the hinge pin fell out and JBL said too bad you are out of warranty, tried to get a replacement pin from jbl but they only carry spare parts like leads etc. Would never purchase anything from JBL again

When I first got the earphones they were great however within a few months they fell apart, the little screws came out, the cushioning thing came off, most of the buttons dont work and now the left side doesnt make any sound. The earphones also randomly disconnect all the time, very frustrating.

I acquired my JBL Duets via a redemption offer with Samsung. I was delighted with the quality of the sound, the seal was great and they felt awesome, and battery life was more than adequate. However, within twelve months the left earpiece had fallen off.
I was meticulous in my care of these, and my previous NC headphones were Sony's which were still good after 6 years but the ear muffs had started to delaminate with age.
Closer inspection of the JBL headphones revealed a flaw in the folding mechanism which is required for it to fit in its sof...

They don't block exterior noise and seem to actually amplify voices - so pretty bad for commuting when the inconsiderate passengers are talking on their phones. The connection drops out all the time so I have to use it with the cord. The earpiece broke off after a few weeks, so had to fix it with a bit of wire. Wouldnt pay money for them and only have them because I got with samsung deal.

Received free from Samsung.
Good quality build and sound, comfortable for on ear.
Terrible Bluetooth connection. Drops connection and sound all the time when phone is in pocket.
Super annoying, almost to the point of useless.

Sound is pretty average quality. I use everyday to watch netflix or stan for around 4-8hrs. Got mine for free as part of the Note 9 last year in Sep. In the last 2 months the left ear has had a rattle. Followed by the fabric coming off as the glue hasnt lasted. Its now hard to get the ear into the hole without adjusting the foam and fabric. Would never get jbl headphones again even if they were free. These are fustrating as and now looking to buy some as they have at least shown me i want a decent pair of bluetooth noise cancellation headphones. So glad i didnt waste $300

I did not find it comfortable in my use. Ear star aching. Need some improvement with the system. Its not coming into use because of ear ache it creates. Wireless was + point. For running its not comfortable but slow cycling is ok. Specially good for bus ride n walking.

A decent product for price range and overall. The noice cancellation is a sure winner, my wife is over the moon about them. I would definitely recommend, but too early to tell if they battery will last.

Battery doesnt last long, they dont hold connection with my device well , got them with samsung redemption and wished i had have sold them before opening. Not impressive and will not reccomend

The noise cancellation is pretty solid and so is the bass. Audio desperation could be better, but I’m using the Bose QC35’s as a point of reference for that. Overall decent for casual use.

These are great. They are comfy and have a long lasting battery. The sound is fantastic, I normally use them when watching movies or tv shows on my phone or laptop. The wireless range is fine
