Review: I was looking for clip on headphones for year but could never find the right ones. They were either crazy expensive or from some sketchy unknown brand. I've heard good things about Koss so I gave these a shot, here is a list of the pro's and con's I have with them: PROS: - good build quality, they are all plastic but don't feel cheap like your everyday library headphones. - good sound quality, even though the drivers aren't held snug against your head by a headband, the sound was surprisingly good. - they fit comfortably around your ear, even with glasses on. CONS: - the cable feels very fragile, at just under 2mm thin it feels like I could cut them with my fingernails. make sure that the cable isn't stressed or bent when using or charging. - the battery life is okay, surprising for its size. But at lower charge (~20-30%) they will give low battery 'beep' warnings until they shut off. I'm not sure if this is something the headphones do or my phone but It also sometimes sends frequent push notifications to your phone while at lower charge, which can get very annoying. PRO/CON: - They are very light, apart from them clipping to your ear, you barely feel them. But because they are so light, the button control will swing quite a bit while exercising. all and all, pretty good headphones, make sure you keep them charged.
Review: These are not KSC75s so no they are not the wireless version of that. The KSC75 is in its own category. Their sound quality is without equal in the audio space--especially at the price they go for. These BT221is have great sound quality for what they are which is great portable bluetooth headphones great for an active person. Let's go over all of the negatives first. 1) The bluetooth connectivity is the weirdest I have ever seen. I have been using bluetooth stereo headphones since 2008 when the iPhone 3GS gained the ability to play stereo over bluetooth. So I am very aware of how bluetooth works. The iPhone remembers the volume that was last used on every headphone you connect. So when you disconnect a device and come back to that same device, it will be at the perfect volume that you last used. Well this device throws that idea out the window and reconnects at 80% volume always. You can literally see the device increasing the volume from where you last set it to 80% volume right after connecting so this is BY DESIGN. These headphones are really not that loud so the person complaining about getting deafened by the headphones is full to it! Also these headphones take a ridiculous amount of time to reconnect to my phone. Around 15 to 20 seconds every time! I have never seen any bluetooth device that worked like this. I have used dozens of BT devices and they all connect in 3 to 4 seconds at the most! 2) They feel really cheap and plasticky. 3) They let all sound in as they don't even cover your ear opening. They perch at the top oj your ears so you will hear everything going on around you which is also a positive actually as you are going to be aware of your surrounding if walking or hiking(which is what I use them for. Here are the positives 1) They sound great. They have the Koss sound! Sure they lack bass but honestly your ears will adapt and after about 10 minutes, they sound just as good as any other pair of decent headphones. Great clarity and awesome midrange. 2) They are able to activate Siri which Koss doesn't even advertise. Just click the center button twice for Siri 3) The microphone is pretty good. I talked to my brother for a few hours and he never mentioned that he was not able to hear me fine. 4) Battery life is better than advertised. I get about 8 hours which is 2 hours more than claimed. 5) Charges quickly. Takes about an hour and a half for full charge 6) The controls are easy to use. They spaced the volume buttons far enough from the play pause that you are able to use the controls without fumbling really quickly. Much better control than the Koss Ports Pro wireless. 7) So comfortable! they disappear on. your ears! They are so light you will forget that they are there. 8) They also have a really nice open sound stage due to their above the ear design. It is some weird kind of magic going on. How can a headphone which does not get near your ear opening provide any kind of decent sound? One of the common complaints is that the ear clip breaks off. I believe this is because people are trying to push the headphones down to ge the driver close to their ears. This is also why some people are saying they are uncomfortable as they try to jam the things down their ears instead of just leaving them up on the ear where they belong. The best way to put these on to be comfortable and secure is to rotate the clips out and place on the ears and then push the drivers close to your ear. This might also be why some people have the cushions fall off. If they leave the clip close and shove the clip on your ears, this might lead to quick wear of the cushions. I have only had them for a week but I have worn then for 14 hours or so and so far there is no indication that the cushions want to come off. Anyway, I love these headphones and I recommend them despite their idiosyncracies

## Questions & Answers

**Q: Are thes good for running or will they fall off too easily?**
A: thes don’t good for running but good sound

**Q: Will all of the functions of the in-line microphone & remote work with Spotify on an Android phone??**
A: Yes, the in-line mic and remote will work with any smart phone when paired via bluetooth. You can even double tap the power button to activate SIRI and Google Assistant.

**Q: Where do I get replacement ear pads for the BT221i headphones?**
A: Way late with this answer and I doubt the original person is still concerned about this but there is a person on eBay currently selling 5 pairs of replacement pads for these headphones for only 10 bucks!

**Q: Can these be hooked up via 3.5mm jack as well as Bluetooth?**
A: No, they are bluetooth only. Personally, I prefer the sound quality on the wired ones that they do - best value for money headphones you can buy. But I can sync these up with my watch over bluetooth so I don't have to take my phone when I go out running - handy.

*by D***N on 6 December 2021*

I picked these as a replacement for Sony MDR series headphones, long discontinued. They are comfortable to wear, although in the long term, I worry that the ear loops lack of spring loading may weaken over time. For reasons I do not understand, every time they connect, the volume is near maximum, a feature which not present on other Bluetooth headphones, so I always lower the volume prior to starting any media. Unlike the Sony MDR though, these have a microphone, and remote controls, so they have more versatility.
