Review on BLZK Wireless Earbuds: Latest Bluetooth 5.0 True Wireless Bluetooth Earbuds with Enhanced Bass, Immersive 3D Stereo Sound, Built-in Mic, LED Digital Display, Fast Charging (Black) by Nancy Ruesink

So I bought these to replace another brand of wireless headphones. The sound quality is good. Nothing special. The noise cancellation is mediocre at best. If you put things further in your ear, they work better. I found this pair quite uncomfortable if left in the ear for more than a few minutes. My main criticism and complaint about them is that I followed the instructions to plug them in and they appear to be decent quality headphones. However, after listening to music for about 2 minutes, the right channel began to randomly drop out. Spend fully for about 3 seconds. then it turns on again for about 2 seconds and then turns off again for about 15 seconds. then it can stay on for a few minutes or turn off again after a few seconds. I wore them to mow the lawn. The phone rests on my shoulder, literally about 15 inches from the headphones. And both channels on and off. I have old LG "necklace" bluetooth headphones and never had such signal issues. In my home or small office work environment, headphones tend to work better than Bluetooth. The signal can bounce off walls or whatever, but outside running or cutting grass these things are just junk. I never got a chance to fully test the battery life as the sound was terrible, so I never wore the earbuds for more than around 90 minutes. After the right channel was cut off so much, I just couldn't take it anymore. Do not recommend this at all!
