The FiiO M15S Music Player has received overwhelmingly positive reviews from customers. One customer who previously owned the M11 for two weeks preferred the physical configuration of the M15s, stating that it felt more premium and had more power. However, they noted that the sound quality differences on IEMs were marginal if any to their ears. Another customer found the device to be incredible and exceeded their expectations in terms of features and hardware quality. They praised the built-in FiiO music player app and noted that the controls were well-designed and the whole device felt like quality. Although the unit is somewhat heavy, it is suitable for travel, and the volume dial works exceptionally well. The device is self-explanatory, and while the instructions could be better, the device comes with a short printed user's manual.
