The left earbud can only be used when the right earbud is also used (the right earbud controls the Bluetooth transmission). Please keep the left earbud stored in your charge case to avoid losing one of your earbuds.How is the noise cancellation for call quality in the wireless earbuds?Jet engine or lawnmower noise might be reduced by -25 dB, while a piercing higher frequency like a siren (ambulance, police) might only be reduced by -10 dB.My wireless earbuds have audio dropouts sometimes. Why so?In dense environments with strong magnets, the sound on the left earbud might drop out for a split second. This is because magnetic interference shortly prevents the right earbud from syncing with the left earbud.How do I get the best sound quality out of my earbuds?It is extremely important to try out the different ear tips that are included in the packaging. You will notice that having the correctly fitting ear tips for your ears make a significant difference in the sealing, fit, comfort and, very importantly, sound quality. A poorer sealing means that more sound leaks, which results, for example, in a flat non-existent bass.All ears are unique and so are yours. It might be that you need a different ear tip size for your left ear then you need for your right ear.Where can I buy replacement earbuds in case I lose them or they become defective?We do not sell replacement earbuds separately.
