The Tozo’s Golden X1 Earbuds are recommended for everyone who loves music and would like to own comfortable pair of earbuds with a great range of sound quality. I would recommend users who buy this device use the right comfortable ear tips as per their ear design. Then listen to music on flat equalizer mode and then do the ear test from the Tozo app and you will feel the difference in the quality of the sound frequencies as it will increase or reduce to your ear setting. The earbuds support LDAC (24-bit) audio with ANC with Bluetooth 5.3. The earbuds come with additional 6 pairs of silicone ear tips.
