True to the Purpose ADVANCED (formerly ADV.SOUND) M4 is one the most accurate in-ear monitors on the market, with each part precisely manufactured from the best suited premium materials. The finely-tuned dynamic drivers and the tailor-made acoustic filter recreate the natural and balanced sound with stunning details. Its lightweight, durable and vented aluminum chassis is sand-blasted and diamond-cut elegantly. Extremely durable, NEVER-TANGLE twisted cord and the premium Comply Foam eartips combined with the M4's superior audio performance provide an unparalleled aural experience.
Comply Foam Eartips Delivering maximum noise isolation for a superior audio experience, the premium Comply Foam tips have integrated Wax-Guard, preventing wax from entering the sound port, which will diminish sound quality. They also provide amazing comfort and stay-in-ear fit for prolonged listening sessions — so you hear music the way it was meant to be heard.
Never-tangle Cord The twisted cord is extremely durable and is essentially tangle-proof, providing a worry-free and comfortable listening and ownership experience.
In-line Remote / Mic The in-line remote provides convenient controls for music playback and answering/ending phone calls with the built-in microphone. The remote and microphone function is compatible with iPhone, iPod, iPad and most smartphones and tablets with 3.5mm jack.
