Product Overview

JBL LIVE 400BT is a sleek set of on-ear wireless headphones. Each earcup sports a 40mm dynamic driver. It comes with JBL's Urban Noise Control, which is a form of passive noise reduction aided with TalkThru and Ambient Aware functions that make conversations easy while listening to music.

Sentiment Score 34%
Reviewers from rtings have found the following***:
The JBL 400BT have a deep, consistent, and powerful bass, a well-balanced mid-range, and good treble. Their bass is a bit too thumpy at times, but some people may prefer this. They're lightweight, easy-to-use, and decently portable. However, they don't block a lot of noise for busy city commutes, and their on-ear design isn't as comfortable as over-ear headphones.
