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.

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.

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
