In regard to sound, this set performs better than the price tag ($25.99 at time of writing) would suggest. They definitely get loud enough to drown out most of the outside world in your typical settings. If you use these in the office, you'll never hear your phone ring or people talk to you. But maybe that's exactly what you're looking for! The audio is full with balanced representation throughout. The only area I felt these headphones lacked slightly is on the lower end of the scale. Bass was represented here, but not to extent of the LyxPro HAS-30 set. The bass is reasonable, I don't feel like it's missing...but it could be represented a little better. The highs and mids are crisp and clear, nothing sounded muddled or blended together in a variety of genres. Where I felt this set performed the best is in video. Movies and TV sounded so much more clear and of a substantially higher fidelity.
I'm realizing now that I forgot to mention phone call quality in my video. While I did only test this briefly, I could hear the other callers with no issues and they could hear me clearly too. I was told that they couldn't have ever been able to tell I wasn't using my actual phone.
Overall, these are my new favorite bluetooth headphones. I personally think the cost of these is too low as I wouldn't hesitate to spend over $50 on them. Most other headsets at this price point feel cheap, have a garbage battery life, and don't sound nearly as good. LyxPro did this set right and I would confidently recommend these to anyone in the market for a new bluetooth headset. Everything about this set looks/feels/sounds much more expensive than it actually is.
