Synchros E40BT is rated 3.4 out of 5 by 101.
Rated 3 out of 5 by from Quality? I never right reviews this is my first one so here goes. Overall its a solid headphone great sound, comfortable, sleek design. My problem with the headphone is its quality this is my second one already im having the same problem with my second pair i had with the first one. The left side stopped working and its not like im a careless person im very overprotective about my stuff. The first time it happened i thought maybe it was the actual headphone was broken,but twice... So overall for its price great headphone but lesson learned "cheap is expensive" i would recommend it but you get what you pay for if you have the cash go for better quality

Rated 4 out of 5 by from Great purchase so far I was looking to replace a pair of old headphones that I used at work to drown out background noise. I wanted wireless headphones that could be used wired too if needed but I didn't want to pay an outrageous price. The Varsity Stripe COACH Limited Edition has everything I needed and looked great too. The travel pouch is an added perk too because I don't just use them at work. I travel a lot so they'll be necessity for me in airports and on long flights.

Rated 5 out of 5 by from JBL has one of the best sound on earth! I am totally amazed by the quality even though the price is not high. The color is great and the sound is legendary. I like the purebass performance very much. Definitely one of the best wireless headphones out there.

Rated 5 out of 5 by from Battery life and sound I got these for Christmas, I took them out of the box and used them almost non-stop for about a month before they died, plus, the sound quality was absolutely fantastic, I would like a little bit more bass though, and the little screws on the front fell off, other than that 6/5 ⭐️

Rated 5 out of 5 by from The best headphones after 10 years of seraching! Works great with my iPad, iPhone and MacBook. Just funtastic! And second thing is; these headphones have outstanding sound quality - great bass, very good range of medium tones, pleasant, soft high tones. Excellent quality. Third thing is: bluetooth connection quality is just outstanding. You hardly can see a difference between cable and BT connection. And the last thing: they can running a whole week for me on one battery charge! FLAWS: - head-rest thing should be made of light steel, not plastic - speakers fastening should be more tied - power-on switch should be SHIFTED not PUSHED. Or pushed, BUT put deeper to avoid accidental turning on/off JBL, please, just made THE SAME pair of headphones, head-rest thing made of steel, better speakers mount and power-on switch improved and I'm running to the shop like crazy for another pair :)

Rated 1 out of 5 by from Plastic part broke in two months I love the size and design and sound quality. However, the right side adjustable plastic band broke in two month and the left side part developed cracks. I will not buy this again. I am trying to get a replacement under warranty and will bond a reinforcement.

Rated 1 out of 5 by from Disposable I got them as a gift 1 year and a half ago. Loved them and used them almost all the time in the bluetooth function and out of nowhere the left side just stopped working. In the beginning it was sort of a malfunction that would go away after moving a little the device and now it's almost impossible to make it work. Saw here and in Amazon that almost all the bad reviews are for the same reason, so although JBL is aware of the problem, no solution has been proposed to those who have passed the warranty period. My next pair of headphones will not be JBL for sure.

Hello I bought a JBL synchros E40 when I charge them, how do I know that they are charging? because I see no light glowing on the headphones or the bluetooth button.

Asked by: GIjoe
When the E40BT headphone is charging, the bluetooth symbol located on the left ear cup should be a solid red light. Once the headphones are fully charged, the red light should turn off completely.

WHAT STEPS DO YOU NEED TO TAKE TO PAIR THESE WITH A TOSHIBA L 70-A LAPTOP THANK YOU

Asked by: BILL ASHBY
If your Toshiba has the latest 4.0 bluetooth version, than go to the bluetooth menu on your computer and put it in search mode. Press and hold the bluetooth button on the headphones until the light flashes red and white indicating that it is searching for a device. The headphones should be display on the search field on your computer after a few seconds and you should be able to connect within 5-7 seconds. Because every computer has different bluetooth components and software, this process may take a bit longer.
