Powerful big-stage bass, and no strings attached. Introducing JBL T450BT on-ear wireless headphones. They are flat-folding, lightweight, comfortable and compact. Under the hood, a pair of 32mm drivers punch out some serious bass, reproducing the powerful JBL Pure Bass sound you have experienced in much bigger venues. Music and call controls/microphone are placed on the earcup. And because your music should go where you go, you will get up to 11 hours of uninterrupted audio playback on a single charge.
