Rated 5 out of 5 by from JBL Synchros E50BT headphones, solid performance! This is my second product from JBL, the other is an original Flip bluetooth speaker. I bought these headphones due to the positive experience I've had from the speaker. They both provide absolutely rock solid bluetooth connection. I can have the source player in the kitchen and potty around the house with no disruption in connection signal. To me, connection stability is more important than sound quality, but do you know what, JBL have refined their products for a top notch sound. The Synchros E50BT's have a powerful neutral sound, which makes listening to all source materials a delight. Well done JBL, I will continue to purchase and recommend your products in the future.

Rated 5 out of 5 by from Best in its price range! I'm using these headphones for 1.5 years actively. Still has good battery condition, with every day use can last up to 7-10 days, ever used aux cable that comes in the box Pads are nice, soft, comfortable, 50mm driver delivers a rich bass and clear vocals. Only disadvantage: no carrying/travel case for headphones is included in the package, that's why because of carrying it in back bag there are couple of scratches on. Definitely worth to get one, good investment for long time use.

Rated 5 out of 5 by from I love these headphones After a lot of research, I settled on the Synchros E50BT, and honestly I couldn't be happier. The sound quality is amazing, and I just started using them yesterday! Great distance on the Bluetooth reception, I can walk across my office without having to carry my phone with me, and the battery life has been great thus far. Have used them 8 hours now and I'm still showing full battery. My one complaint is the ear cups themselves, as they don't completely cover my ears, but they do create a pretty solid seal and I don't get any noise from around me in the office with them on. I love the ability to run passive as well, as I will be traveling over the holidays and know I can't have Bluetooth on during the flight. Overall, I am very pleased with these, and they have again proven that JBL should always be my choice when selecting quality speakers/headphones. Love you guys! Thank you!

Rated 5 out of 5 by from My best headphone ever! I bought it ~2 years ago and I'm very satisfied. Excellent sound and features. - My phone is in the house on charger and I listen music at the end of garden. 40-50 meters. Cool :) - Unpluggable cords. Great! - Don't press my ears after 5-6 hrs. -

Rated 4 out of 5 by from I'd Buy it Again This is an excellent headphone, especially for the money. Sound quality is excellent for this price range: bass is clear, musical and well-defined without being pumped up; mids are very musical and highs are musical without being bright, often a problem with competitive models. Setup is easy and operation is simple. Battery life seems good but I've never run it down. They look nice and isolate outside sound well. Comfort could be a little better and it takes some fiddling to get them where you want them. There are more comfortable phones at this price point but these sound (and look) better.

I'm having a hard time trying to connect my e50bt to my pc (windows 7 64 bits). At first I thought the issue was with the bluetooth adapter, but the headphone won't work in my girl's notebook also (windows too). The device pairs, but doesn't connect.

Asked by: Biorlo
It is possible that your computer does not support or is not setup to support Stereo Audio Bluetooth connection. To use the E50BT with your Windows system, you'll need to find a Bluetooth driver that supports A2DP Audio codec. Your best bet is to go into your control panel and find the Bluetooth setup. If you don't see the Bluetooth section on Devices, chances are that there are issues with Bluetooth driver. Make sure to go to Device Manager to verify the driver is present and installed correctly. If everything looks alright, but you don't see the option, you may want to download and reinstall the latest Bluetooth driver from your computer's manufacturer support website.

I have q I use pc and use usb blueyooh and I geting sound Jams where can be problem?

Asked by: Edvard
If Edvard is correct and you are using a usb Bluetooth adapter I have found most have buggy drivers. Often companies re-bundle drivers into easy install packages which increases the risk of said bugs. It can be worthwhile to source the original driver, which can be a hassle but if you look up "How to download the correct driver from hardware ID" it will likely give many walkthroughs as to how.

Different audio sources all playback at different bitrate qualities. Browsers sound TERRIBLE, but mp3's can sound great and clear in the same listening session. Quality also drops randomly during listening session, also hardware beeps as if code. What?

Asked by: gilbot
I have a set of these and I have found after installing the "Forward VoIP Calls to Handsfree" Bluetooth service on Windows 7, it will every now and then switch over to that instead of "Listen to Music" which is the "normal" service. When this happens the quality drops to sounding like hearding music over a phoneline. Switching back to "Listen to Music" fixes this instantly (for me). I have a sneaking suspicion that "Lync" triggers the VoIP thing to activate, but I don't really know.

I bought the E50BT headphones to use with my Windows 7 laptop. However, while I *appear* to successfully pair the headphones with my computer, I cannot get them to connect. I have updated all drivers. Need help. Also, details on procedures and indicators.

Asked by: frostygus
This headphone works well on my Windows 7. Be sure to select "Listen To Music" than "Play Music". I have also encountered this problem until i figured out that.

Asked by: Majesty
Hello! Sadly, the Synchros E50BT does not feature an IPX rating and are not designed to be overexposed to water as it could compromise the controls and sound.
