Summary: These earbuds were a bargain. The performance is an upgrade compared to my Panasonic ones I purchased last year. The bass is very good, deep and generally clear. Highs and midranges are good, but muffled by the bass Noise reduction is excellent. Compress the gel foam around the earbuds before putting them in your ear. It expands for a perfect fit. My wife was telling me what she wanted me to do and I couldn't hear a word!!
Summary: Awesome!! good clear sound lots of bass. I got them for a Christmases gift. I've had many other brands but these are the best ones. They fit really good in my ear canal without falling out..I highly recommend them.
Summary: I bought these for my twelve year old daughter, she did not like the material the earbuds are made of. They don't stay in your ears and they are not loud. The quality is horrible. I would have returned them, but she threw away all the packaging before we talked about them. I wasted my ten dollars.
Summary: The PLUG is a rather affordable cananphone that I'd say is in the typical KOSS mould, which is tuning towards a greater bass response (versus clarity and treble favoured by Audio Technica for example) As per any canalphones, the fit of the supplied foam cushions will greatly affect the quality of sound you get. A very tight fit (having big ear canals, I reversed the cushions as recommended...
Summary: Even though this is my third pair of these, I have never doubted Koss products. From my first purchase to now, these are still my favorite earbud earplugs. I wear them everywhere, and that's why I lost the first two. When I saw these on a display at Walmart, my first thought was, "I could listen to my music and mow the lawn now! And without buying $100 pair of over the ear phones!" But these were more than headphones, this was like listening to erotica in surround sound!
