Bests & Worsts Reviews from Amazon

Battery life is really good. I use them when commuting as well as when working at the office. (~5 full hours/day) I appreciate a good isolation level and the one provided by this headset is nice. Since I use glasses the fit is kinda harsh right where the temples rest since they are on-ear but I knew that before buying them so I'm ok with it. Besides that they provide an excellent fit for me. Sound quality is good, however compared to my Sennheiser HD202 these are a little bit low on the mid range. The JBL performs really well on the low end and a little high on the high range which will be an issue when used for a long period of time (anyway I take breaks from the headphones from time to time because it's healthy for my ears so I workaround that (Bass: 8 Mid: 6 High: 6 would be my satisfaction level in a scale from 0-10) EDIT one year later: Since I had given such a good one review for it I'm forced to tell my whole experience. I'm careful when dealing with my devices: I never never dropped them, used them at a reasonable volume, always carried them within my backpack, etc. etc. I should also say I made exhaustive use of the headphones: work,commute,home,travel you name it. But I was really disappointed when yesterday, out of nowhere, the left speaker stopped working (via bluetooth & cable). I did some google search and found out that it was not a very often issue however there are some mentions of it. Long story short: I tried with another pair of crappy in-ear emergency headset and they worked so the issue was not the laptop nor phone, tried plugging in the cord on/off and nothing, charging (logically nothing to do with it) and also nothing. Cracked them open to see if the left speaker was properly wired and it was. Got angry, smashed them several times against the floor and threw them into the garbage can. I can surely say that JBL is a really good brand, I'm not here to blame them for it, but that's why I expected much MUCH more from the headset than only one year of service. I would NOT recommend at all buying this headset from my personal experience.
