The MM 30i Noise-Isolation In-Ear Stereo Headphones with Mic from Sennheiser are designed to put you directly in touch with your music and calls. Each earpiece has a dynamic speaker that provides clear, natural audio with a wide frequency response and excellent bass performance. Multiple sizes of eartips are provided, letting you find the best fit to create a seal in the ear canal that blocks out unwanted ambient noise. This makes the headphones ideal for use in loud environments, such as airplane cabins.
An inline microphone and 3-button remote allow you to make phone calls, take voice notes, control music playback, and adjust volume on compatible smartphones and MP3 players, such as the iPhone and iPod touch. The cable provides plenty of slack and has a gold-plated 3.5mm mini plug for wide compatibility.
