CalmbeeHybrid Active Noise Cancelling Headphones, Bluetooth 5.4 Headphones Wireless Over Ear with Mic for Clear Calls, Hi-Res Audio, 90H Playtime, Transparency, Deep Bass, Dongle Connect, Custom App

Honestly I was hesitant to buy this brand for I hadn't heard from it before. But reading the reviews about them, I noticed that they were quite good and, with only one or two more brands, were given 5 stars, something very rare. And since my budget was under U.S. $200, they were in this budget.It helped too, that I read it had a 5.4 Bluetooth and that the battery lasted quite long. Well, I decided to bet on them after a lot of comparisons with other similar and better brands.I must admit I was quite nervous the days prior to receiving them, for it was a brand not very well heard of. But then, I received them via Amazon on the days programmed, no delay I must admit. I have been with them already like 3 months and I must tell you that I couldn't be happier with the product. The Bluetooth it's great, the reception it's amazing and at a distance I couldn't believe it, crossing closed doors and walls. The battery last for ever, I hardly think about it, lasts like 3 weeks!The sound quality is fantastic: great bass and very good highs (treble). The sound cancellation, even though it's quite simple (only 3 positions) works very good! No complains.I've had like three or four more headphones before: over the head Soundcore by Anker (Q45, U S. $110) and in the ear: Sony & Xiaomi. And even though, Soundcore was a very good brand and very publicized, must admit, I almost go for the "Space one" (U.S. $99) model that sounded very attractive too. But went for these Calmbee (U.S.$ 79!) and I'm not at all repented!They are extremely comfortable to wear for long periods, you hardly feel them on you. The materials made of are very nice and of good quality for the money you pay.There's only one little (big) inconvenience, and that is the app (Rythflo)..., it doesn't work very good, the options aren't the best. For example you choose a "Sound Effect" but it doesn't stay, after some minutes it goes back to another ramdom selection, and the "Custom EQ" you configure doesn't stay, it erases after a while. This is the only inconvenience I found with these great headphones, but I'm sure Calmbee will look into this app and deliver a more potent, adequate and accurate respond to such great headphones!I recommend them 100%, and for this price couldn't ask for a better equipment.

I have two sets of Headphones ... One dedicated to my iPad and one to my Windows 11 PC, I really hate conflicts when I turn one or the other on.I've had the same headphones for my PC for years and they finally decided that they wanted to be retired. At the time I purchased them (13 years ago) they were among the very best you could buy.One of the important features I wanted was 2.4Gh connection ability because of the low latency for gaming and bulletproof connection characteristics. Obviously, I wanted easy to listen to frequency response as well.What I didn't expect was to pay $70 ... To be honest, when I placed the order, I wondered what I was doing. The thought that I was going to be happy with a headphone that cost less than a $150 made my skin itch, but less than half of that?I was pleasantly surprised by the weight, build quality and immediate comfort level. My system locked on to both 2.4Gh and BT within seconds of turning them on. The 2.4 was rock solid and had reach that quite honestly amazed me. The biggest surprise? ... they sound quite good. Frequency response is smooth, bass is a little strong, which is fine for gaming, but not so strong that it overpowers my classical music. Mids are clean and easy to focus on. The highs are there but not overpowering. In other words, I'm enjoying my music while my gaming is still exciting.This headset is very easy to recommend to all but the most demanding audiophile.

I like the sound that comes from the headphones but they definitely are not noise canceling. And that is why why I only gave them three stars.

Quality runs through and through the Calmbee Hybrid Active Noise Cancelling Headphones. The unit is stout in build. While heavier than other units, they are comfortable and do not squeeze excessively. The ear cups surround your ears and seal well to block out noise. The noise cancelling function is very good at blocking out unwanted sounds. One feature I like is the transparency mode that will allow conversation without removing the phones. The ear cups are soft and replaceable under warranty. The sound is on par with phones from notable brands. I would have kept these phones, but they recommend downloading an app that was not found in the Google Play store. Following their link directed me to a foreign unsecured site. That was the deal breaker for me. Otherwise, this is a nice product. They sound great out of the box and I can only imagine how much better if using the app.

I bought these headphones and they’ve been great. The noise cancellation is effective, blocking out background sounds, and the sound quality is clear and balanced. Most important, it pairs quickly and uses the newer usb jack. They have a long battery life. I can't really comment on the app because I don't need it.

These headphones sound great, pair easily and are quite comfortable. They're a bit large and the ANC goes off every time you pause but, overall, they're winners.

These headphones are comfortable, if you don't want to hear anything. Had them for <3 months and they started to not work well. Now, it's like listening to garbled videos with the sound cutting in and out. And that low latency "0.04" seconds, not at all. It takes more like 3-5 full seconds before it turns off to hear YouTube videos. Any other type video formats and it's a crap shoot.Oh, and there's no app on Google. And when I go to the Rythflo website, it's blocked by my phones security software.

I am hugely disappointed. While easy to set up and adjust the volume, I noticed an immediate drop in sound quality from my previous headphones, and within the hour had a constant stream of crackling and audio cutting out. On top of that, the wireless connection loses efficacy after stepping a short ways away. I couldn't walk from my office to the kitchen without it immediately disconnecting. Overall, just not worth the price.
