Excellent headphones

  • from Edmonton, AB

Very nice But...

I got these when they were on sale and they sound very nice and feel very solid. The only thing is that they use non standard aux and charging cable which is not easy to find if you need want to get spares. Other then that. they are worth it.

Sounds not great

Sorry but it's not worth the price they ask for. Sound is not that great, kinda crappy. Nothing like my other headphones. I took it right back!

Stopped working after a few months

I really likes these headphones and bought two pairs. they worked fine and always connected but all of a sudden they stopped working in one ear. about the weeks later the same happened to my wife's set. can't recommend but it's unfortunate because I really liked them.

Great Balanced Sound and Excellent Overall Value

I was a bit sceptical at first since I didn't realize that JBL made headphones. Boy was I ever Wowed!! These headphones are SO comfortable to wear, they fit great even on my big head, and the ear cushions are very comfortable. I was very impressed by the sound quality as well, truly didn't expect they'd sound so smooth!! I can hear the highs, mids very clearly and the bass is unbelievable!! Very well balanced! The controls on the device are also easy to use right from the get-go and they sync and operate perfectly from my New BlackBerry PRIV Android smartphone...I'm truly a happy camper and would highly recommend these, at the very least try them out in store before hand!!
