Verdict

The Sennheiser MM 30G is a lightweight, 11g in-ear headset specifically optimized for Samsung Galaxy and Android devices, featuring a 3.5mm 4-pole connector and a 1.2m symmetrical cable. It delivers a balanced, bass-driven stereo sound with a frequency response of 17 Hz to 20,000 Hz, a 16 Ω impedance for easy driving, and a sound pressure level (SPL) of 106 dB. Main characteristics include a 3-button in-line remote with an omnidirectional microphone for seamless call and music control, alongside an ear-canal design that provides effective passive noise attenuation. Key pros are its comfortable fit with three sizes of ear sleeves (S/M/L), high-end dynamic speaker quality, and durable build. Potential cons include a limited soundstage typical of in-ear designs, sound that some may find overly 'coloured' due to its V-shaped frequency curve, and the lack of a dedicated carrying case.
