Synchros E40BT is rated 3.3 out of 5 by 148.
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 Great Product The sound quality of this product is great. It is really practical to have the Bluetooth feature for wireless listening, which is the primary purpose for this product, surprisingly for a Bluetooth set of headphones, sound quality is not distorted. WIth the cable, the headphones work just as well, it is however very easy to lose the wire, as I did, and as far as I know, I cant purchase another wire.

Rated 5 out of 5 by from Great battery life! I owned these a couple months ago, after a few weeks started to lose some parts, and started to feel a little fragile. Despite, are the best headphones. I ever had.

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 Great fit, Sound, and style I Love them so far. I thought they didn't fit properly around my ears but It was user error (I'll admit it). I also like that nobody else has them in my gym. Always love the sound quality from the subs in the trunk to the headphones on my dome.

I have an E40BT from 2016 and recently the two small piece with play symbol has fallen off and I couldn't get it back on. since there was glue mark on it; is it safe to superglue it on?

Asked by: DAN333
Thank you for reaching out to us. If this two small piece with the play symbol is just the logo, there should be no issues gluing it on; if it's an actual play button on the controls, we cannot recommend using any glue or adhesive. If you have any more questions, please contact your local JBL customer support, thank you!
