Best in its price range!

By Abil

from Baku, Azerbaijan

Comments about JBL Synchros On-The-Ear Headphones:

I'm using these headphones for 1.5 years actively. Still has good battery condition, with every day use can last up to 7-10 days, ever used aux cable that comes in the box Pads are nice, soft, comfortable, 50mm driver delivers a rich bass and clear vocals. Only disadvantage: no carrying/travel case for headphones is included in the package, that's why because of carrying it in back bag there are couple of scratches on. Definitely worth to get one, good investment for long time use.

Good price, average quality

By Milton

from Brazil

Comments about JBL Synchros On-The-Ear Headphones:

Like everything else in Brazil, the products are more expensive than in the USA. At half the price I would buy the same product in the USA. It has a reasonable quality of sound, the bass is still weak, the treble with a little distortion when the volume of the music is too loud.

I brought these at the begining of March and by the end of April the left side wasn't working. I sent them in to be fixed with the warranty and they said it'll take month. After a month still nothing the end of August where they come in and it turns out that they still werent fixed so i waited again till the end of October where i get them back completely working and a week later the exact same thing has happen where left side wasn't working at all.

Good piece of equipment, but not perfect

By korniak

from Gdynia, Polska

Comments about JBL Synchros On-The-Ear Headphones:

I'm not that much of a music-addicted-geek, but I value good quality music equipment. That being said I have to say that E50BT is a *very good* piece of wireless equipment, but it's not perfect. Below a few things that IMHO could be improved: - buttons on the left side should have some "3D markers" (I don't know how to call it exactly) to identify which button I'm pressing - now I encounter situations where I think I'm pressing "Volume Up (+)" but actually I'm pressing the start/stop button - sound quality (especially high tones) isn't bad, but could be better (I know you can do better!) - folding the speakers is pretty much useless (at least for me), one cannot actually decrease the size of the headphones, which is the expected result of folding, It just changes the shape of the headphones a little bit - the pressure of the headphones on ones ears is a little too big IMHO (but this is probably user-specific), makes it a little painful to wear them when using for a long time
