The verdict

If you can get onboard with the idiosyncrasies the TOZO NC2 sports, its ANC is quite impressive. The connection and touch controls are effortless, and the battery life is good. Downsides include the exaggerated bass and that the charging case doesn't seem as long lasting as the IPX6 rated earbuds. Still, for the bargain price tag it's difficult to think of a better ANC capable set of earbuds.
