Great choice for on-the-ear headphones
I bought this for my mom. She’s very picky on earphones. She is SO happy with them. I tried them as well. They’re very nice on-the-ear headphones, especially for the price.

Great value
How can u go wrong at this price??

Can’t complain – the price is so low and the sound quite adequate.
Good cheap headphones suits its purpose – hearing sounds.The heaphones I rec’d came quickly, but unfortunately the hard plastic packaging was damaged (but not the mailing envelope) and one of the earpieces didn’t work. Got my refund and am looking for a suitable replacement. The most inconvenient thing is that each earpiece has a wire and they merge into one microjack. The wires can easily get twisted/tied around the earpieces unless you take extra caution to prevent that.I will be looking for a headphone that requires only one wire from the jack to the headphone.

Take it when flying. Better than airline headphones.
Made by Koss. A well known maker of high end speakers. Excellent sound quality.

Not Really Comfortable for Adults
It’s an inexpensive headphone set and I use them all the time. I have bought these previously and they work for my budget. The soft foam allows me to still hear ambient noise, which is what I want.The fit is not great for an adult head and seems more appropriate for a child.Sound is good for watching TV or casual music listening.Another company has a comparable unit that allows both earpieces to pivot. It feels much better than these but it is also a weak point that easily breaks. These are okay for casual use and I am hard of hearing and wear hearing aids. These aren’t studio quality and certainly not ideal for serious listening but they work for what they are designed to do.

I like these very much. I’ve seen them for sale for radio use and I wanted a small pair of on-ear headphones for ham radio cw use. They are great, light, decent-sound at the necessary 400 – 800 Hz that most morse code is done at, and robust so they are unlikely to break if chucked into a rucksack for portable operating. And at less than £10 you can’t question the value for money. Only down-side is that that you have to drive them quite hard compared to ear-buds and another thing to bear in mind is that they don’t isolate much, so you can still hear things going on around you. That’s neither positive nor negative, just bear in mind that in loud ambient noise you won’t hear the head-phones. Highly recommended for cw.

KOSSの音が良いことで有名なヘッドホンを昔使っていたのでこれを購入しました。最初に音楽を聴いてみてがっかりしました。高音がやや低め。ただダメ元で使ったテレワークの会議で疲れなくてとても良かった。聴き疲れもなく、とても安くて、そこそこ、と言う感じのヘッドホンという印象。頭の形によっては、特に頭のサイズが大きい人は少し当たるかも。
