Decent

Well constructed, EQ on app doesn't really do anything, buttons on unit are in a horrible spot. Biggest complaint would be the volume. Not loud enough. Noise canceling works okay.

This item has gotten good reviews, and as it's a gift, I wanted to make sure the recipient will be happy with both the sound ad the noise cancelling qualities. The price was competitive with other sellers and ordering was quick and easy.

Whats the difference between the 350BT and the 450BT other than the 450 having ANC?

A shopper on Oct 31, 2021

Thanks for your inquiry. The notable difference (other than cost) between 350BT and 450BT is the 450BT has ANC and a higher charging current (500mA max) due to ANC.
