Review: All complaints are true but I still love 'em! - 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
Review: Good value. One notch below Porta Pros, but still good! - My go-to headphones are wired porta pros, but I wanted something wireless for listening to podcasts and music while walking around home or at the gym. For twenty bucks they are certainly better than anything you'd pick up at Walmart or Dollar General for the same price. Pros: * Good sound * You can hear your surroundings * Comfortable semi-adjustable ear clips * Wire is good for taking the headphones off and wearing them around your neck * Good tactile buttons * Easy to pair Cons: * Always connects to phone at way to loud of a volume (might be an Android issue) * Sound is probably the best you can get for $20 and wireless, but it's still noticeably worse than $40 wired porta pros * Mic quality is meh. * Micro USB port These are good for low movement exercising like weight lifting, but I am not sure if they would do well on runs.

## 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.

### ⭐⭐⭐⭐ Good value. One notch below Porta Pros, but still good!
*by V***R on December 14, 2024*

My go-to headphones are wired porta pros, but I wanted something wireless for listening to podcasts and music while walking around home or at the gym. For twenty bucks they are certainly better than anything you'd pick up at Walmart or Dollar General for the same price. Pros: * Good sound * You can hear your surroundings * Comfortable semi-adjustable ear clips * Wire is good for taking the headphones off and wearing them around your neck * Good tactile buttons * Easy to pair Cons: * Always connects to phone at way to loud of a volume (might be an Android issue) * Sound is probably the best you can get for $20 and wireless, but it's still noticeably worse than $40 wired porta pros * Mic quality is meh. * Micro USB port These are good for low movement exercising like weight lifting, but I am not sure if they would do well on runs.

### ⭐⭐⭐ They sound very good, I use them for running. Great option - UPDATE - connection drops
*by S***I on January 7, 2019*

Update Jan 16 2019 - Downgraded from 4 to 2 stars. Connection kept dropping in crowded NYC subway train. Not sure if the public wifi that requires sign in at every station or many commuters with bluetooth devices cause interference. Bit really annoying. Not sure if I got a defective unit. Still waiting on Koss customer service. Amazon rep told me to try to put the phone in airplane mode and turn the earbuds off for 60 seconds and pair again. 2nd issue is one of the very thin ear pads came off, and does not stay on securely. I wonder if there is adhesive or better earpads as a replacement. Sound is good, I have not compared it directly to the Koss Porta and Sporta pros that I own, but seems pleasant. ----- I have been using Koss Porta Pro and Sporta Pro for years. Very nice sounding at a great price. I started running and I did not want to have my phone wired to a headphone to avoid tangles or destroying the cable. I wish Koss made a bluetooth version of the KSC75, that i do not have but have the same drivers as the S/Porta pro. Anyway these to my non audiophile ears, sound nearly as good. Warm sound. Of course they do not stay as close to the a ears like a real headphone like the Porta Pro. I prefer over ear than in ear because if i am running I want to hear environmental sounds and be alert, I also want to avoid possible ear infections that can result by in ear earphone usage. I also considered getting a BT adapter for half the price of these, and use it on the Sporta Pro. I may do that in the future on some occasions, but then you need to wrap and tie the cord, and also you lose the phone mic possibility. These have a nice controller on the cord. On / Off, stop playing, volume up / down, or next / previous song with long press. I hate that the battery does not seem to be replaceable, so after a year or so these would end up in a landfill. I wish Koss offered a spare battery or battery replacement rather than making an item that is disposable after the expiration date.
