Bought a second pair of Technics AZ80 at a good price in Amazon (I know battery life will probably last about 2-3 years) because I love sound quality of these TWS. Just tested the AZLA SednaEarfit Crystal for TWS (for Samsung Galaxy) and sound quality is even better than with regular AZLA Crystal for IEMs. Much better sub bass and extended treble and resolution in LDAC Best Sound Quality settings. Perfect fit (L size for me, the same as Technics standard silicone ear pads) It seems that the shorter stem improves the perception of AZ80's diaphragm vibrations. Impressed so far!
