36+ Jbl Headphones S400Bt Pictures. The s400bt headphones are nfc paring capable with compatible devices. Jbl signature sound customer review:
It's the latest addition to the jbl synchros line of headphones, inspired by premier jbl nightclub sound systems found the world over.
The highs are very sculpted as well, so the synchros s400bt rarely sounds. If the battery is exhausted, simply connect the audio cord and continue listening or talking. They pick up a very large amount of the sound spectrum without giving u the part of the highs that seem to cause ear fatigue. These e some pretty amazing headphones.
