Review: Great product and great service - Great product and complete value for money. Good signature sound, sturdy built, long play time and great fit while working out or dance or running. What else you want. ANC is not that great but still manageable.. Have been using unapologetically for almost 2 years. Had some issue with speaker in one ear. The service were prompt to respond and quick to resolve by sending a replacement and without hassle. Strongly recommended.
Review: Good for the price!! - Quality: the build quality of the product is pretty good for the price,have comfortable set of earcups. The ears do get hot after long hours of use and the padding or cushioning on the top of the head/ headpiece is not that great. The overall build is quiet strong and flexible. The sound quality is not for everyone, if you are a person who loves bass,dont buy this product. This headset is not for bass lovers. It can provide a good seperation of both low and high notes, the sound clarity,treble and the rest pretty good. It also supports Aptx and AAC. Overall sound clarity is good but not for bass lovers. The box includes the headset itself, a 2.5 to 3.5mm jack, type a to type c cable, manuals and a carrying case( more like a pouch with seperate room for tje cable). Also the earcups don't fully tilt 90° and I personally wish the headsets extendable part to have a bit more length. The headset itself feels a bit heavy imo. The portability is good,since you can fold this headset, it doesn't take a lot of bag space. The ANC on this is not good at all. Microphone is good and the transparency mode(which only works during calls) is also good. You do have app support,but there is not a lot of features in the app, you can personalize your EQ and adjust the level of the transparency mode. Overall the headset is good for the price.

### ⭐ Terrible service and headset too small and has audio playback
*by D***A on 26 January 2024*

If you use this product during calls or while gaming in voice chat there is an audio playback which makes it so you can only hear yourself and the game sound is barely audible and its bad. The headset is also too small for ears which make it hurt. The wire did not work as intended and bt is not compatible with all versions. The amazon’s return policy is absolutely garbage as i had lots of issues with this including incompatibility with my pc but could not return this product. Not ordering headsets or any peripherals from amazon anymore.
