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
