JBL Synchros S400BT

 

The JBL Synchros S400BT is a Bluetooth headphone pair that delivers absolutely thunderous bass in a comfortable design.

Powerful, distortion-free audio performance with intense bass response. Detachable cable for optional wired listening. Exceptionally comfortable, even over long listening sessions.

Highly sculpted sound signature. Easy to accidentally pause music or place unintentional phone calls.

If you love the idea of monstrous bass response, but find that the Synchros S400BT is a bit out of your price range, the SOL Republic Tracks Air is a slightly-less expensive option, while the Outdoor Technology DJ Slims is a solid, inexpensive...

Durable construction ; LED light trail gives it a slick look ; It’s able to fold up and occupy very little space ; Lot of strong bass with its audio quality ; Touch sensitive controls

JBL Synchros S400BT review

 

Incredible sound and design knocked down by connectivity issues

Magnificent design and sound ; Long battery-life ; Comfortable

Spotty Bluetooth signal strength ; Price is a bit high

With cheaper wireless alternatives available, the S400BT doesn't put forth the winning argument it needs to justify a higher price.

JBL Synchros S400BT review

 

Solid build ; Weighty bass ; Exciting sound

Loose fitting, unintuitive touch-controls ; Overbearing bass ; Lack of detail and refinement

A patchy performance from the JBLs: the fit isn’t quite right and neither is the sound
