Very happy with the wireless earbuds. Quality and price can't be beat. Only con is that I'm not hearing much if any bass. Disappointing but still happy with product.

These headphones have great sound. Hard to find any better in its price range. Sensor buttons unfortunately leave room for improvement. Sometimes they do respond, or respond not the way intended, so i mostly use my phones buttons instead

They are compact, lightweight and easy to use. I would like a little longer battery life, but that's a minor thing. I have a smile on my face every time I use them.

The quick summary? If you are considering these, just place the order! OK… so I already had two Koss ’phones before I bought these: The Pro4S Studio Headphones, which are very good (though large) and the BT115i Bluetooth, which I have had for several years and found to be excellent, especially for the price. But when I saw the TWS250i buds on sale, I thought I’d give them a try, though I wasn’t expecting much, since they are a fraction of the cost of similar earbuds. When I received them, I was quite surprised. The case and buds are finished nicely, and the sound quality is excellent — and I am very picky. If these were $100, they’d be a good value. For the price, they are an incredible value. My only criticism — and it is minor — is that while there is a nice variety of included tips (small, medium and large), the large is not large enough for my large ear canals and doesn’t provide a tight seal (hence, missing bass). I swapped the tips from the BT115i and the bass improved immensely, so I purchased some large aftermarket tips and now everything is tight and sounds great. So, perhaps Koss could include a larger pair of tips, or offer more tips for sale as accessories; I think that would be a good idea.

Bonne qualité sonore, dommage que l'autonomie soit faible.
