Put the earhook on the back of the ear and slightly rotate it to adjust the sealing and comfort of the earphone for better Audio experience Review: GET THESE, NOT THE AZ15s - I originally bought the "upgrade" from this model, the AZ15. The difference is night and day, BUY THIS ONE. The az15 had loose ear hooks, a terrible connection, a charging case that would only work by the whims of Loki himself, and the actual adapters began to randomly disintegrate. But THESE, these are solid, they are robust, a great sound, secure ear hooks, in my opinion better and clearer sound, a connection that will not desync and play desynchronised songs in each ear when someone turns a microwave on in the next town over, and good reliable charging. My new daily drivers, at a price 20 quid cheaper than the next model up, buy these bad boys. Review: Brilliant!! - Changes a pair of wired kz into blue tooth in ear monitors! Absolutely amazing, great battery life, same great sound, but without the cables in the way, a bonus when you’re working. Only regret is I didn’t buy them years ago! ## Features - MARESTREAM EARPHONE COMPATIBLE KZ AZ09 provides Cpins connection used for ZSN/ZSN PRO/ZSN PRO-X/ZS10 PRO/ZS10 PRO X/EDX PRO/AS16/AS16 PRO/PR2/ZEX PRO/AS12/AS24/DQS/C12/C10 CRA/ - Bluetooth 5.4: KZ AZ09 has an excellent Bluetooth chip.
