More Details
The Koss BT539i Wireless Bluetooth® Over-Ear Headphones feature Bluetooth® technology pack powerful wireless sound into a portable, fold-flat unit.

The Koss BT539i Wireless Bluetooth® headphones have the natural fitting, iconic D-profile earcup, first featured on the ergonomically designed Koss Pro4AAA and now available on many Koss headphones. The D-profile mimics the shape of the ear, creating an excellent seal for the most consistent sound reproduction.

Listeners stay connected using the built-in microphone. Easy to locate, on-board controls allow listeners to quickly navigate through songs, play or pause music, change the volume level, and answer incoming calls.

The built-in rechargeable lithium-ion battery delivers up to 10 hours of play time or 9 hours of call time (at moderate levels) and 40 hours of standby time on a single charge. If the rechargeable battery runs out, the BT539i comes with a detachable analog cord, which can be used as an audio bypass.

Closed ear cushions fit comfortably around the ears to block outside noise and keep music from leaking out.

When the music stops, the Koss BT539i headphones fold flat into a convenient size that is easy to carry and even easier to store.

Love it!

Very good headphone for the price ! It even have the looks 😀

Love them, but...

Love them, but the LED on these should seriously cool down, my room feels like there is a plane going to take off.


Great sound as always, despite having Bluetooth 4.0 sounds great and haven’t had a problem connecting to multiple devices at the same time.

inexpensive high quality bluetooth headphones

I have been using my BT 539 headphones for about six months. They have been great. They hold charge for long time periods as promised. They provide good sound quality. They are durable (I have not been "challenging" them), comfortable and were easy to pair. This is a good entry level set or headphones for those of us without professional ears. Over and above, Koss customer service is among the best on the planet. (It's a long story why...but this set is replacing my last pair of Koss phones, higher quality, more expensive, and very old when a plastic part gave in and "died", cracking with stress fatigue.)
