Rated 5 out of 5 by from Best Build Quality and Ideal Driver Size The 50mm drivers in these headphones are my new standard. It delivers the bass I need to hear for modern music. The build is awesome! I really hope JBL keeps expands on this flagship product and gives it the necessary attention/exposure.

Rated 5 out of 5 by from Amazing Headphones! Recently got these headphones as a replacement for my S500's and they sound fantastic! Although they are nice, I do have 2 complaints... Number 1: The headband is a tiny bit smaller than the S500's headband, so I have to pull the band down to the 2nd notch. Other than this I think the build quality is superb! My number 2: The Livestage DSP really doesn't make much a difference in the audio. On my S500's I noticed it way more, but it does work and all, but would have preferred it to be more noticeable. Overall I am really happy with the headphones despite my 2 setbacks. I definitely think this is a good pair of headphones for audio files, music producers, and even your techy person in your life. Owning these headphones I get asked, "What are those?" Many people ask to listen to them and get blown away. Totally recommend these headphones!

Rated 5 out of 5 by from Stall happy after all these years ... Bought these when they first came out ... and remain very pleased. I run them through a small Bravo Audio tube amplified for added impact. Could not be happier.

Rated 5 out of 5 by from Awesome headphones! I've had these for about two years now. Got em when they first came out and I still love them. Great sound for both passive mode and Live DSP. Keep up the good work, JBL.

Hello, What is the impedance of headphones JBL Synchros s700 please ..?

Asked by: mosquito69
The S700 has an active and a passive mode. As a purely passive headphone, it has a 32 Ohm impedance. In active mode, it is a high-impedance load, around 2.2 kOhm. This is because the source no longer looks into the speaker drive units in active mode, but looks into an amplifier, which does not place any load on the source, needing little energy.

I live in a small flat and can hear my neighbours music which interferes with my listening to my television or my own music.  I have some Bose headphones but they have to be attached with a plug to the device but I want headphones for my tv no wires.

Asked by: Frances
Hello, your tv cannot connect wirelessly to the S700 headphone. You would need a usb dongle or similar solution for bluetooth connectivity. BR Rob

Other than the cosmetic chrome appearance, what is the difference in the synchros 700 headphones and the Synchros Chrome Edition

Asked by: Chzynachoslayer
The Synchros Chrome is not a wireless headphone as opposed to the Everest 700 which you have the option of wireless or can also use an audio aux cord. The Synchros Chrome features AAA batteries which allows you to have up to 20 hours of LiveStage technology which is a digital signal processing that enhances headphone audio to recreate the experience of listening to a live performance. The Everest 700 features the ShareMe 2.0 which allows you to connect to Bluetooth headphones and share music. The Chrome features a 50 mm driver as opposed to the Everest which features the 40 mm driver. Both headphones have a frequency response of 10Hz-22kHz.

I've noticed that they sound slightly hollow unless I press the buttons on the cable. Holding any/all of them down results in a much richer, roomier sound. I'm guessing that there might be a problem with the cable. Anyone else experience this?
