KossBT232i Wireless Bluetooth Earclips, In-Line Microphone, Volume Control and Touch Remote, Sweat Resistant, Dark Grey and Black

Very light weight, with great sound and comfortable but secure ear pieces. I buy about one headset a year for work. Being I own shares in KOSS, I figured, why not try them out. I've been more than satisfied so far

I was a long time fan of the wired sport clips as they were the only headphones that fit my very small and super pliable ears. I thought these would at least be similar despite other reviews mentioning downsides of heavy controller and thin loose wire but I was way to optimistic. Not only are the other reviews about the heavy controller and flimsy material true, but the ear clips are so flexible they hold no shape and fall out of my ears super easily. Their base line shape is way bigger than the sport clips and only stay in if I'm sitting down or walking with no bouncing or shaking of the head. Audio quality is not great with an iphone speaker "tinny" sound. The loose hanging wire is super irritating and the heavy controller being on one side actively pulls the ear clip out of your ear. Why they didn't just take the shape and material from the sport clips and create a wireless version of those is beyond my comprehension.

I wish I could give 5 stars for service. I bought this product in February. By end of April, they stopped turning on. No idea why. I called amazon, and they were outside the return period. But, amazon and Koss worked together to allow me to send them in for a free replacement. I just received the new product and it’s working well. Fingers crossed they stay that way.In terms of product performance, as mentioned above, the first pair stopped working after 2 months.Other than that, I was happy. They did their number one job: stayed in my ears, playing music while I exercised. I’ve taken calls while running as well. No problems.In terms of functionality, the volume / battery is heavy and placed in a way that requires the loop be in front of you when running instead of behind your neck. That’s irritating as it means the cord flops around. It would be great if they had a clip. Not a big deal for cycling, or something where you’re not really moving your upper body, but it’s annoying for running.Also, sound quality is only ok. It’s great for the price, but the bass is lacking.Still, as I said, for someone who needs this type of product because of small ears, etc, these work. I’ve used the wired fitclips for years, and now I’m a convert to the Bluetooth.

These are inexpensive but pretty well designed headphones. Battery life is ok (I get around 6-8 hours as advertised). For the price, sound quality also works (but obviously not as good as the Porta-Pros). More importantly, they stay in my ear when every thing else seems to pop out. For long workout sessions, the control bar on the right might cause some imbalance/discomfort. But overall, I am happy with this pair.

I like + have used Koss products for years. I adore my PortaPros, and Fit Clips provided the best combination of price, durability, secure hold, and sound quality for running.No such luck with these buds. The left ear started buzzing after my first run. They then temporarily died (would neither take a charge nor turn on), came back to life for a few days (one charge's worth of use), and are now dead again.Bummer, particularly because the sound quality (when not dealing with buzz) and over-ear hold were, as with their wired analogue, really good.

I'm a big KOSS fan, but these didn't last much more than a year before I started losing sound in the right ear. They fit in my ear decent enough, but they would pull out with how the cord adjuster worked. With that said, they sounded great, wireless worked without issue, and battery life was pretty solid. I liked them when they worked, but I have to downgrade them since only lasted a year. I used them mostly for running/exercise and occasionally at my desk.

These headphones are great. I wish it were designed a bit differently because the remote is kind of heavy on one side, but overall these are great for working out, especially if you have small ears. Koss is the only brand I've found that consistently makes headphones I can wear because my ears are smaller than average. These are still a little big, but totally doable and comfortable.

These stay put and I can hear everything plus the person on the other end can hear me cleary. I am amazed at how long the battery lasts. I always feel good about Koss since they stand behind their products and give you a high quality of performance.
