Quotes from the Reviews - What People Say about:

Battery

Battery:
"positives:* good build quality - last pair (from a different mfr) broke at the hinge* good sound* decent battery lifenegatives:* bt disconnect is aggressive if you don't have something playing for ~5 minutes* proprietary charger piggybacked on stereo jack - prefer micro usb* no controls for seek etc."
_
"the battery went dead 3 months after i bought it, went to use it hardwired and the pin wouldn't fit."
_
"I was happy with them when they worked, but I would not recommend these because of the problems I've had with the battery not taking a charge."
_
"Had them for 5 days for $50 from store sale great headphones feels like the battery last for ever."
_

_
"The construction really blocks out background noise so you can listen to your music at low volumes and still enjoy and the battery lasts a long time."
_
"Great battery life, also amazing for working out."
_
"These are great headphones, they have solid battery life, good sound, and range and are very comfortable, but the one major design flaw I've found is the placement of the power button, it's right where the headphones rest if you wear them around your neck, and all it takes to turn these on or off is one touch, so my issue is everytime I go to use them their off because at some point while walking around I've hit the darn button and shut them off lol hence the 4 star, these would completely be 5 start headphones if it wasn't for this major design flaw."

Bluetooth

Bluetooth:
"I am not an audiophile, but they are durable, easy to connect via bluetooth, and can also be wired."
_
"Also the speakers twist left and right so you can adjust them on your ear but they are stiff and the Bluetooth button is a bit annoying because whenever I try to adjust the speaker to my ear."
_
"Now a days headphones with Bluetooth don't get the best quality."
_
"This was my first pair of bluetooth headphones and I was very disappointed."
_
"Bluetooth connection failure after two months of use"

_
"They hold a great connection via Bluetooth."
_
"Sound is ok, Bluetooth is a great touch, wdont expect to be using the Shareplay feature (who do you know has these? )"
_
"But at this price range, and with Bluetooth, the best you can possibly have believe me.4."
_
"Overall, best bluetooth headset at this price range, yes there might be some that that have better sound or some better design, but in general, these are just simply great headphones all there is to it."
_
"Nice sounding headphones and the Bluetooth makes everything better."

Charging

Charging:
"The only negative is that the charging is done with a special cable and not a standard USB charging cable."

_
"), and was unable to charge when I lost them for a while."

"More problems: they charge via a custom cable (USB aux cable, not microUSB), and the audio cable (in case you are not using them wirelessly) is a custom cable not a normal audio cable."
_
"I am disappointed that the charging cable on the E40s and E50s is JBL's own proprietary mini - jack to usb cable, and not a standard micro USB charging cable (the kind Android phones use)."
_
"It is very easy to charge, connect, pair and use (both wired and wireless), sound quality is ok."

"These are great headphones, they have solid battery life, good sound, and range and are very comfortable, but the one major design flaw I've found is the placement of the power button, it's right where the headphones rest if you wear them around your neck, and all it takes to turn these on or off is one touch, so my issue is everytime I go to use them their off because at some point while walking around I've hit the darn button and shut them off lol hence the 4 star, these would completely be 5 start headphones if it wasn't for this major design flaw."

Headphone

Headphone:
"Apparently multiple people have been having problems with one headphone, in my case left, stop working for no reason, and coincidentally right after the return window closes."
_
"My headphone had a problem with only 2 weeks of use."
_
"Now a days headphones with Bluetooth don't get the best quality."
_
"These headphones are a bit weird on my head."
_
"This is if not, the best headphones you can buy especially when its on sale.1."
_
"In fairness I love these headphones and am fully happy with them and would say if you in the market for a solid set of on ear bluetooth headphones for a very reasonable price then look no farther, but the power button thing is a fairly large inconvenience, mainly because I bought these to double as both headphones and hands free in the car, but they are somewhat failing at the latter because their ALWAYS OFF lol so I'm driving and I have to quickly put them on, then turn them on, and them answer the phone call, the only real saving grace is the fact that they do pair very quickly... but I would say if JBL makes another set of these in the future the number one thing on the list would be MOVE THE DARN POWER BUTTON lol."
_
"Good Sound quality no complaints so far and there my first wireless headphones."
_
"Had them for 5 days for $50 from store sale great headphones feels like the battery last for ever."
_
"Worked good for about a month, then today, the left headphone went out."
_
"Other than that great headphones, crisp sound and awesome bass tones."
_
"These are very nice headphones."
