### ⭐⭐⭐⭐ Good overall
*by T***. on 12 October 2024*

This product surprised me with the immersive sound without blocking exterior noise, they work really well and battery life is amazing. I also use them a lot in the office for calls and listening to music, without losing awareness of what's happening around me. They are very light which means I can use them for extended hours with no pain or uncomfortable feel in my ear. Controls work really well and have different functions, other similar products only change song or play/pause, but these also control volume and voice commands to Siri or alike. Never been able to go 100% on volume, they sound really well and with the customized equalizer you can adjust to your liking. My only concern is if I use them while running or cycling, I fear they may fall. Haven't tried it though.
