spent 3.5 years at work. Also, they are still functional, which is amazing considering modern technology. Nowadays, the battery drains quickly (I've noticed it in the last six months; prior to that, it was normal), one ear occasionally wheezes (not often), and the white cotton insulation has darkened (I even washed it with soap once). I had to replace the damaged ear pad with some others that were the same size because I don't know whose ears are used to produce the additional little and large

The headphones are comfortable, charge quickly, the battery is not bad. The only negative is the flimsy pin for attaching to anything, broke after a few days.

I am very disappointed that they worked for less than a year (((. I replaced the battery, they began to work for about 5 hours, but if you leave the charged headphones for a day, they will still be discharged, self-discharge occurs. ((((

The clothespin turned into dust: after a couple of days of use, the clamp angle immediately broke off, after 2 months of use, the spring mounting bracket broke off altogether. The plastic is very brittle. Such a trifle spoils the whole impression of the device, because. the sound and stuff is very good.

First impressions are very good! However, I would also like to understand why the signal disappears in some places on the street. . .

Well, I charged it every day, since my shift at work is 8 hours, I had to charge it often. And the rest is normal, the only thing that the mount broke after 6 months.

Went with wired CX300/CX400. I thought that JBL would not pull out my tracks, but I was pleasantly surprised. A good wireless analog with the sound I'm used to.

Everything is fine, if not for the PARK store where they were bought. The seller deceived and put a damaged headphone fastener on clothes in the package. Left a bad impression. Please check the packaging carefully before purchasing.

Quality item. A little bit about the sound quality: citizens, adjust the equalizer! The sound volume is more than enough. The kit comes with a clip for attaching the battery and a case, which cannot but rejoice. I am satisfied.

The biggest impression about this model is its excellent assembly. I accidentally forgot the headphones in my pocket three times, they withstood 3 full washings in the washing machine and still work))) A miracle of technology)
