Review on 🎧 BLZK K1 Wireless Earbuds with Upgraded Comfort, Immersive Bass Sound, True Wireless Bluetooth 5.0, Noise Cancelling Earbuds with Microphone for Sports (Black) by Stacey Jones

I tried wireless headphones after losing my old favorite pair. Day 1: Fiddled around with sound calibration and different earbuds. Then I used them during my workouts at the gym. - They mate very easily. - Sound fidelity seems good. - The volume is sufficient, but hardly. That's important to me because I don't hear very well. Most of the time I have to turn the volume up to the Samsung warning limit or a little higher. Although the volume could be better - the soundproofing is excellent, so I'm happy with that. - The microphone is ok, but could be a bit more sensitive. The recording I left with him as a test was a bit muted. However, there is no background noise, so everything is fine. - The charging case is cool! Works as advertised with fairly fast charging and a digital headphone case charge status report. - The range seems good, as I found when I accidentally stepped away from my phone while walking to the pool. The signal went through two walls 50 feet away. - The beep was solid. With others I had problems because one ear and then the other fell out intermittently. There is no such problem with them. I'll update this after trying them out for a while, but for now they look like Guardians!
