The verdict

For less than the price of a nice dinner, the TOZO T12 provides good sound quality and great passive isolation. There's no companion app or active noise canceling, but you can't really complain at this price.

✓Liked: Great isolation, Good frequency response, Price, Wireless charging

✕Could be better: No companion app, No ANC
