Review on 🎧 Immerse in Tranquility: HROEENOI JZ02 Active Noise Cancelling Headphones - Bluetooth, Wireless, with CVC 8.0 Mic, Deep Bass, 40Hrs Playtime - Black by Brian Cox

How it works: The left button turns on/off the active noise cancellation, the right button turns the headset on/off and controls the music source. Pros: These Xiberia DS-JZ02 headphones are very comfortable with soft padding. ear pads and headband. They have amazingly excellent speaker fidelity over a wide range from 20-20,000Hz. Music gets extra rich and clear with ANC engaged, especially at this price point! - Outstanding noise reduction at low frequencies such as aircraft engine noise and ambient vehicle noise. Amazing again at this price - The latest version of Bluetooth 5.0 has an amazing range (much more than the expected 30ft) and connects to my devices in 1-2 seconds max. - Multipurpose buttons for volume up/down and rewind/forward , pause/play worked fine. The 600mAh/3.7V Li-Ion battery was 90% charged, charged quickly and seemed to live up to expectations for 30 hours of playback. - The 20" USB-C charging cable is the new standard in smaller size, higher voltage or data rate, and best of all, it's reversible (there's no wrong way to connect it). - The CVC 8.0 microphone is more than enough to answer calls without taking off the headset. - Carefully packaged at the factory, meaning quality control has not disappointed when used. They are well done. The protective hard case has a textured surface for a comfortable grip. Nicely packaged with a carrying case, 20" USB-C charging cable, 3.5mm audio/aux cable and a small Revain user manual. Cons: Absolutely none! IMHO these are great ANC headphones at an amazing price. Overall verdict: Buy!
