Bluetooth headphones are a great thing to have if you work out or like to exercise with your music. Not having the cord connected to your phone or other audio device is a big help, but it’s important that headphones used this way are sweatproof and don’t fall out of your ear when you move around. These bluetooth headphones from AK do both of those things well, but unfortunately that’s pretty much the only positive things I can say about these headphones.

Right off the bat, the materials for these headphones and the overall design is big, bright, but not very sturdy. They feel cheap and breakable, though they apparently come with a lifetime guarantee. They sit well in my ears and didn’t come loose at any point, which was good. They also stood up to water and sweat well without any problems. But the audio quality on these headphones is just atrocious. They have a horrible echo-like quality, as if all the music if being played in a large empty room. None of the songs, audio books or podcasts I tried sounded good, and with the music the quality was so bad that I lost any desire to even listen to my music. For making calls, the microphone is equally poor, sounding very echoey and distant. I was very unimpressed with both of these aspects.

The control in the middle of the wire works well for pausing, skipping tracks, and so on. It’s light, but it also has an extremely short battery life of a few hours. If you want to use these during the day, for your commute, or for more than an hour or two a day, you will need to charge them partway through the day.

One possible good thing about these headphones is the fact that their maximum volume is VERY high, higher than any headphones I’ve ever seen, but that isn’t something I was thankful for. When I first synced them to my phone, the audio-cue telling me they were paired was so loud that it hurt my ears. If you have extremely poor hearing the high volume levels might be useful, but for everyone else they’re just damaging to your hearing.

These headphones are not very good, and while they are cheap, I don’t even consider them a good purchase at the current price. I’ve seen many headphones with much better quality and features at similar prices, so I can’t think of any reason to recommend these.
