The TOZO T12 is one of the cheapest sets of true wireless earbuds you'll find, yet it still delivers incredible performance.
A 10 puts its noise isolation / ANC in the top 10% of wireless earbuds we've measured.
Measured on 133 of the 271 we've cataloged.
below average for wireless earbuds — based on 243 of 271 we've cataloged.
above average for wireless earbuds — based on 245 of 271 we've cataloged.
IPX8 appears on 2% of the 244 wireless earbuds we've cataloged (of 271).
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.
