Feel free to upgrade your cable with your preferred one Unique Tuning Switch LZ A7 is outstanding because of its unique tuning switch. Each product is provided with different colors of interchangeable earphone nozzles to give a different tuning. They can be exchanged by unscrewing the tube counterclockwise and then screwing on another tube by twisting it clockwise. When screwing on, use a certain amount of force to tighten the tube until the rubber edge is compressed, but do not over-tighten it with tools Supreme Material LZ A7 adopts a special material which feels luxury and cool. The surface is matte with detailed texture. The faceplate is designed with tuning switch, easy to use and change the tuning style Tips for Better Using Experience 1. The earphones are designed to fit the contours of each ear. The "L" side can only be worn on the left ear, and the "R" side can only be worn on the right ear, as shown in the figure. 2. The design of the earphone cable assumes that the ear-hook is hung on the ear to get a professional and stable seal. If necessary, you can use both hands to put on one earphone before putting on the other one. 3. The ear tips on the earphones need to seal over the ear canal entrance. If you find that one or both ears are not sealed properly (for example: no sound isolation, or lacking bass), please change between the different sized ear tips provided until the earphones seal properly. 4. The sound effect can be changed by the dial switch between two modes, ie. POP mode and MONITOR mode. The respective acoustic curves are shown in this figure. The black curve is the POP mode, and the purple curve is the MONITOR mode. 5. Each pair (with a different color) of provided interchangeable earphone nozzles gives a different tuning. They can be exchanged by unscrewing the tube counterclockwise and then screwing on another tube by twisting it clockwise. When screwing on, use a certain amount of force to tighten the tube until the rubber edge is compressed, but do not over-tighten it with tools.
