Rated 5 out of 5 by from Great I bought this two weeks ago and have only used it about 6-8 hrs. I still haven't had to charge it up yet. The booklet that came with it is hard to understand but it wasn't hard to figure out how to use it. I think it will be a good headset. I like the idea that I don't have to have any cables to use it.

Rated 5 out of 5 by from JBL E40BT Headphones I have had my E40's for about 3 months now. They are awesome headphones. When I first used them I was shocked at how good the sound stage was.. excellent rendition. I replaced my Audio Technica ATH-3 with these EB40Tafter 40 years.. There's a reputation on it's own.. Older guys will know what I am on about (ATH-3)..

Rated 5 out of 5 by from These Headphones Sound Awesome I own a lot of JBL products Home audio speakers like the JBL L112, L96, L15. All three sets driven off of a vintage Pioneer SX 1980. My truck even has two pair of JBL T545's in it. I also own several sets of headphones J55A in black and J55I in white. I have now added a set of SYNCHROS E40BT to my collection. I have heard other brands and nothing comes close to the sound quality of JBL.

Very happy with my E40BT. Connected it easily to my PS4 via BlueTooth. Problem: microphone doesn't seem to work. Do you have a solution?

Asked by: Jack Bowe
Due to PS4 profiling concerns, The microphone for the JBL E40BT will not work as the microphone The microphone will only work as a mic for phone calls when connected to a smart phone. What you can try that might work is to connect the 3.5mm audio cable on the controller with the other end connected to your E40 BT  .

I just bought the jbl synchros e40bt bluetooth on-ear headphones. The power light indicator is white (fully charged?). My samsung galaxy note 4 can't find the headphones for blue tooth. HELP.....

Asked by: carolyn4535
A white LED light indicator means the headphone is ON. To have this connected on your phone 1. Press and hold the POWER ON button for 0.5 seconds. The LED light indicator should blink fast if it’s blinking slowly, You need to press and hold the POWER ON button again till it starts blinking fast. 2. Once LED light is blinking fast you are ready to pair to your mobile phone. 3. From any Home screen, tap Apps. 4. Tap Settings. 5. Scroll to 'NETWORK CONNECTIONS,' then tap Bluetooth. 6. Slide the Bluetooth Switch right to the ON position. 7. The Bluetooth Switch moves right and turns green. 8. If necessary, turn on the other device and make it discoverable. 9. Under 'AVAILABLE DEVICES,' tap the device to pair. 10. Tap Scan if you do not see the device.

They won't start on long enough for me to actually do anything with them. They will turn on for 30 seconds and then turn off for no reason. The light is blinking normally though

Asked by: Say_Boss
The Synchros E40 BT should be able to play up to 16 hours depending on audio content and volume level. Please ensure that the headphone is fully charged before using it. There’s a LED light indicator on the right ear cup that goes red when the battery is low.I However if the headphone is fully charged and you’re still having the same concern. the headphones may not working as it is supposed to. If the headphones are within one year from purchase, please do submit an email case to www.jbl.com/contactus and our customer support team would be able to assist with the warranty of the headphones.

I have a HP Windows 10 Intel 15T Laptop Notebook and it has the ability of Bluetooth in terms it can find nearby Bluetooth devices to connect to. But when I turn these headphones on it cannot be found on my Bluetooth in my laptop what is the problem?

Asked by: Tanderson
When switching the E40BT, it would initiate pairing status with the last/previous device that it was paired to. If the headphones were connected to a mobile device it would search for that device and if the device is not available the pairing status would go on standby, meaning, the headphones would not be "searchable" by other Bluetooth enabled devices. You would need to initiate pairing status again on the headphones by pressing the power button once(DO NOT PRESS AND HOLD THE POWER BUTTON), the power button would start to blink indicating pairing status and that the headphone is "searchable" again. The E40BT does not need any special drivers or settings toggled to get connected to computers/laptops or any Bluetooth enabled devices. If ever the device asks for drivers, please perform the following: For Windows Operating Systems, you just need to update the Bluetooth Hardware of the computer/laptop. ** Go to Control Panel ** Go to Hardware and Sound ** Under Devices and Printers select Device manager ** In Device Manager select Network/Bluetooth Adapters ** Once there Update the Drivers For Mac OS, you would just need to update your operating system to the latest version.

I cannot hear the left side of the headphones... is there a way to fix this problem?

Asked by: Sarah Elizabeth
Unfortunately, if audio is not audible from either side, a wire connecting the small driver might have been cut on the inside. If your headphones are within one year from purchase, please do submit an email case to www.jbl.com/contactus for a warranty replacement.

Hello I bought a JBL E40 a week ago , when I try to charge there is no red light glowing. How do I know if it is charging or charged, what should I do?

Asked by: tomthumb
It sounds like it's not holding a charge. The LED lights up red when charging, and changes color to white when charging is complete. Try charging it directly on working power outlet using any USB wall adapter. If this doesn't help, I would recommend to contact the store where you purchased it if for an exchange. If this is no longer possible, please submit a case at www.jbl.com/contactus and the Customer Service team will be more than happy to further assist you.

Hi, I was wondering how will I know if my headphones are fully charged? They are charging now, and the bluetooth sign is on in a red color. Does that mean it is fully charged? Thanks!

Asked by: Anon
The solid red light indicates that the unit is charging. Once the red light on the bluetooth symbol turns off, that indicates that the battery is fully charged.
