Everything You Need to Know About Headphones: A Complete Technical GuideThe choice begins with understanding the design and features.

How to choose a gaming headphoneWe understand the differences between regular and gaming headphones, tell you how to approach the choice of a headset wisely
















- Their "sporty design" absolutely does not mean they will stay securely in the ears during physical activities; moreover, they fall out even when I'm just sitting still, let alone during sports.
- Terrible desynchronization: the headphones lose signal even just a few centimeters away from the phone. When I'm lying on the couch holding the phone, I can't be sure I'll hear the next word properly because one of the headphones might disconnect at any moment, sometimes both. Walking down the street with the phone in my pocket results in the same issue, except both headphones disconnect at once. Once during a conversation, there was a "freeze" in sound, where a normal voice was playing in one earbud and it sounded like it was at 0.1 speed in the other; it was terrible.
- The audio frequently lags behind the video, greatly disrupting viewing, although it resolves on its own.
