I've been using these headphones literally every day for more than a year, and they're still performing extremely well.They reliably and consistently connect to my devices. When I power these headphones up, I simply know that they're going to connect. Not so with my previous headphones that cost nearly as much. With my previous headphones (that did not have any noise cancellation feature), it was a roll of the dice every time I wanted to connect to my devices. Sometimes I would have to cycle them 2 or 3 times just to get them to connect.The build quality is excellent. Battery life is also very good...diminished somewhat if the noise cancelling feature is enabled. They're also comfortable to wear for hours on end.I would definitely buy these headphones again. They're a very good value.Although I rarely use it, the noise cancellation feature is robust, especially for mid-range frequencies. A characteristic of any noise-cancellation technology is a slight sensation of over-pressure, but it's not objectionable. It's most noticeable when the noise cancellation feature is first enabled, and again when it's switched off.I highly recommend these headphones for daily use.I used these as my "please don't chat with me... just leave me alone" headphones on public transportation daily for about 6 months. Loved them. But the left ear quit working at 6 months. I tried to self-repair, but they're impossible to get apart. I feel like $60 should buy more than 6 months. Regardless, they were great while they lasted.Bought it for the wifey and she loves them! If the kids are being obnoxious, she puts them on and zones out their battle cries! Plus the battery life is better than others she’s tried.I wish that noise cancelation would include voice ranges. That is mainly why I bought these. They do a fine job of canceling but can still hear voices.Back in 2019 I purchased the TaoTronics SoundSurge 46 headphones and I love them. They're no longer for sale on Amazon and they Toatronics US won't send their headphones overseas, so I ordered a these ZIHNIC headphones as a possible replacement as the earpads have fallen off and disintergrated.I really like them. The sound is great, although a tad boomy but that can be a good thing depending on the music you like.My only complaint is that the Bluetooth range/distance is really poor and I dearly would love to find a pair as good as these or the taotronics that has the range the taotronics had. The ZIHNIC's start to lose the connection even at 5m sometimes and you'd be lucky to get 15m in a straight line before losing the connection completely. With the Taotronics I could be 100m line of sight and still have a great connection. Or be 20m away and behind two steel shed walls and still get a connection.They're tough and the noise cancelling is great but not quite as good as the Taotronics. Close enough though.So if anyone knows of a set of bluetooth (preferably 5.0+) headphones please recommended them.If you're sitting close to the bluetooth transmitter with the ZIHNIC's then they're ideal. Great for the price.And battery life is fantastic but I do tend to top them up at least every two days.Of course these are not in the same league as the top noise cancelling headphones from Bose, Sennheiser, etc. And for a fraction of the price they shouldn't be expected to be. That said, so far they're a very good value for what they cost. Sound quality and bass are very good. Battery life is good- I can work all day with music and the noise cancelling turned on. Build quality seems pretty good for normal use- I don't blast music or abuse them. The noise cancelling is okay- only 'takes the edge off' loud noises but doesn't cancel them completely. But with that and music I can work from home and tune out the kids making noise. I would buy them again.Not that great at canceling out noiseSound is goodBattery life is goodWish they fit a little better on my head...a little bigThe sounds is pretty good overall. The noise canceling is so-so. My old pair of headphones did better with the noise cancelation. They do the job but I wouldn't get them again.
