    Customers say

    Customers find these headphones offer decent sound quality for their price and work well, particularly for audio books. The comfort and durability receive mixed feedback - while some find the clips comfortable and report they hold up well, others say the hard plastic clips are uncomfortable and the headphones fall apart within six months. Moreover, the ear support is problematic as the foam pads keep falling off, and customers disagree on the fit, with some finding them slim while others say they're too small. The clip quality also gets mixed reviews, with some saying they stay on well during exercise while others report issues with the clips detaching.

    Good Product, Slightly Different Look
    It's a good product. The headphones work well and are very comfortable. The only reason I gave it 4 stars instead of 5 is because the look of the product did not match the picture. The style and function of the headphones is the same; the difference is purely cosmetic.

      Ok, so yeah, I got these to use with the PS4 mostly. I love playing No Man's Sky, but to hear the sound of things that want to hurt you VS the roar of your ship is a wild volume swing should you get in a starship battle... At night? I had two choices, either turn it up to stay alive or keep it down and die. I decided headphones were in order.

      I chose to buy these instead of of other styles because earbuds are painful and never fit right.
      On ear headphones squish your ears and head (especially if you wear glasses like I do).
      I own a pair of Koss UR-20's that I adore, but they get so heavy after a while it's just uncomfortable. (This style being the giant over ear DJ style.)

      The ones here that I bought, these little clip ons, are amazing! If you have issues with the other kinds like I do, you really do need these!

      They are adjustable, light weight, and we'll padded. Though you can hear just fine, these allowed just enough ambient sounds that I could still listen for my kids if they called my name, cars coming, and my phone ring. This meant I could walk or jog safely with music without fear of not hearing traffic or dogs. I use them for everything now, as they stay on and can be moved for comfort... These are just a godsend, and exactly what I hoped for!

      Also please know the seller is fantastic, within a very short time of purchase they had already emailed me, checked in, gave tips and contact info should anything be amiss, and offered assistance immediately should I need it. That my dears is how you do business!

      Great product, stellar customer service, fair price, it's a happy purchase you'll actually enjoy!

      I've had these since 2022, and I bought second pair for home use. I use them almost daily for remote appointments at work (up to 5 hours per day). The sound quality is decent enough I can hear over coworkers in adjacent offices, even at low volumes (our walls are paper thin). They're comfortable enough that I forget I'm wearing them. (I can't stand headband-style headphones with how they press on my head and ears. In-ear headphones hurt. Most clip-on headphones hurt.) The ear clip edges are smooth and rounded. The foam covers used to come off a lot, but it's rarely a problem now.

      I'm buying a new pair because the piece that holds the clip in the hinge broke. I suspect this would have happened sooner if they spent much time unprotected in my backpack or purse. If I could just replace the broken part, I'd keep using them because the sound quality remains good.

      Note: these are headphones only. There's no built-in mic.

      I bought these as a replacement when my Panasonic earphones of the same type died on me after almost a year. I'll be comparing the 2. I chose these because I had a gift card and was a little short to get the Panasonics again (really liked them!).

      The Panasonic phones were thin whereas the Koss are at least twice as thick making them feel bulky and heavy. The earpiece that goes over the back of the ear is hard and unforgiving. I actually have to hook it in the stem of my glasses with some hair after a short time or it starts to hurt!

      About the only thing I like BETTER about the Koss ones is the cord length. It's longer though it's missing the longer cord on one side that allows the user to put the cord behind the neck preventing things from catching it.

      For a cheap pair of phones, these work but if you can spring for the Panasonics or better.

      Bought these to replace some very old headphones that fell apart after 10+ years, that being said these were a gamble to purchase. First out of the package they seem….. very small. However they fit secure on my ears and the sound quality is very good. I imagine anyone standing remotely close to me can hear what I am listening to, they feel like they stick far out from my ears. I wear mine while stationary biking so to overly concerned about fashion. They work perfectly for my need and I am glad to have the added sound quality which was an upgrade from my last set. Some reviewers mention the ear pieces snapping off? I do not see this being a problem for me, possibly a newer model?

      Classic Koss value. For a price of cheap earbuds, you get a great clip-on earphone. The sound quality beats some of the more expensive headphones I have owned.

      I was looking for a earphone with good bass, and I really like my portapro. I didn't like the look of the more expensive Koss clip-on. This is pretty cheap, so I figure I will give it a shot.

      Overall, I am very impressed with the sound quality for the price. It is also very light and comfortable. Being headphone gives this clip-on bass unmatched by any earpubs at similar price range.

      A few things I didn't like. The wire is kinda of thin and filmsy. Probably won't stand too much twisting. It also doesn't isolate outside nosie much. I want to be able to hear my surrounding in my case, so not a problem for me. However, it can be undesirable for some.

      Button line: I love it. Unbelievable good cosidering the price.

      J'utilise ces écouteurs pour une activité qui n'a rien avoir avec la musique donc je ne peux pas juger de la qualité du rendu mais ce sont des écouteurs dont je ne pourrai m'en passer pour mon utilisation.

      Par contre le câble d'origine est bien évidemment trop fin et certainement assez tôt vous aurez des soucis avec. Je l'ai changé par du plus costaud et souder un jack de meilleur qualité (neutrik).
