Review on KZ S1 S1D TWS Bluetooth 5 Headphones by Harish Soto

This is great. I use them with ALL KZ with foam tips. silicone never. First, my favorite earbuds are the 5 zs10 ear drivers. This is not a valid comparison, so I will compare with ZST, ATE and ATR. The sound quality is partly on par with the ZST, which in my opinion is the better of the three mentioned. Other than that, the volume on my device is VERY low for those using public transport in a big city, however it would be great for working out as you can hear cars going by, people screaming, etc. This is not for noise cancellation. however off. To do this, try a bluetooth adapter and as16 or zs10. persons
