Synchros S700 is rated 4.8 out of 5 by 20.
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 Great sound Jbl sent me these for a replacement on my S500 which had a wire problem. Love the sound with the rechargeable battery The headphone case is very difficult to arrange; trouble putting headphones away. That's why it's a 4 star not 5

Rated 5 out of 5 by from These are the best headphones I own I bought these for a graduation present to my self when i finished high school. I have to say i did a lot research on headphones especially when i am about to spend a lot of money and these were the best ones so i bought them. They are so greatly built and light weight. the only thing is i wish that the cups were like deeper if you know what i mean, can't really think of the name or how to describe it. They are also tight on the head to which i do and don't like

Rated 5 out of 5 by from Amazing Headphones! These headphones are the greatest ever. I love the fact that if the battery runs out the headphones aren't useless. In fact, it's far from it. For one they sound comparable to any set of Beats by Dre headphones and I'm not even talking about when you actually turn them on to use the LiveStage setting. Once you turn them on the depth and quality of sound blows my mind. I've owned a pair of Beats by Dre headphones and I'm not going to lie, I loved them. They even wore out and on day they just wouldn't cut on. I'm very careful with my device too so it's not like I was careless with them. These JBL headphones are study. They've for metal support and housing but it's still not too heavy for the head. I absolutely love them. Worth every penny.
