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.

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.)

Amazing

The sound quality is pretty good for this price
The Charge time is basically nothing compared to the life it has
The design is very fresh and smooth
It’s pretty straightforward

The only problem I have is with the thin headband and maybee the cushions being a little thick.
But other than that I love them. 9/10

Great, except for the fit.

I have been a loyal Koss customer since the early 70's, when I got my first Pro4AA. Since then, I have always looked to Koss first whenever I had a headphone need, and I have always been extremely satisfied. That's why I am so regretful to report that for the first time, I have had to return a Koss product.

Wanting a wireless, over-the-ear product, I purchased the BT539i. The pairing instructions were a breeze, and as usual for Koss, the sound quality is fantastic. However, I was only able to get them over the top 2/3 to 3/4 of my ears! I extended the headband all the way, and even tried bending the steel band outward to get them to fit, but the bottom of my ears still stuck out beneath the ear cups.

Btw, I am not an exceptionally large person. I'm 5'10", and have a hat size of 7 1/2.

I'm sure a company like Koss is constantly working to refine and improve the next generation of their products, so I hope you will find the following suggestion helpful:

Could you please extend the headset band about 1 inch further on each side. I think that not only would this allow the ear cups to fit properly, but also enable the wearer to fit it over a baseball hat.

Like I said, Koss has always been my first choice for headphones, and despite this episode, will continue to be so in the future.

I hope you find this respectful message helpful, and I look forward to the day when I can get a Koss wireless, over-the-ear headphone that fits comfortably.

Sincerely,
Steve
