The buttons are tactile and responsive, with both data and charging USB-C ports for added ease of use.
Audio Performance
The M18i shines in delivering a clear, detailed, and balanced sound signature. It works exceptionally well with high-end IEMs like the Sennheiser IE900 and over-ear headphones like the Sennheiser HD660S2.
