[What are the differences between different ear tips?]
(1) Red and black ear tips: bass ear tips, which can improve the bass sense.
(2) Translucent black ear tips: balanced ear tips, actual listening experience may vary from users.
(3) Red and white ear tips: vocals ear tips, more outstanding on mids performance with front vocals.
(4) Translucent white double-flange ear tips: design for the small sound tube which can be inserted deeper into the ear canal for richer sounds.
(5) Memory foam ear tips: more fitting for ear canals with better sound insulation and noise cancellation effects.
(6) SpinFit ear tips: provide a skin-friendly, fitting and comfortable wearing experience.
[How to choose suitable ear tips]
The external size of the sound tube is 6.0mm, so it is suggested to choose ear tips with an inner diameter between 4 to 5mm.
The cable of the FH7S is detachable with standard MMCX connectors. (Compatible with FiiO's cables with detachable MMCX connectors, including the LC-B, LC-C, LC-D, LC-RE, LC-BT1, LC-BT2, UTWS1, UTWS3, UTWS5, IRC-MMCX).
