Advanced Sound M4 IEMs
Advanced Sound M4 IEMs

From Matt Takaichi, Audiophile Community: "Advanced Sound is a new and quickly advancing player in the IEM market. Its IEMs aim for a rare combination: providing good value while also delivering a neutral, accurate sound signature. I've had the chance to demo a lot of the company's upcoming products at CES, so keep your eyes peeled: There's more exciting stuff to come."

Balanced Sound, Durable Build

The Advanced Sound M4 is quickly gaining a reputation as one of the best IEMs under $50, and for good reason. Featuring custom-tuned dynamic drivers with a special acoustic filter, these IEMs are all about naturally balanced, accurate sound, more on the analytical side of things, with plenty of gorgeous detail. And because you’ll want to make these your everyday go-to, they’re built to go with you every day. Sandblasted and diamond-cut, the aluminum chassis is at once lightweight and durable, while the flexible, quad-braided cable is virtually tangle-proof—so you can pull the IEMs out of your pocket or bag and get straight to the music. Finally, the inline remote has a built-in microphone compatible with most smartphones and tablets with a 3.5-millimeter jack.

Note: This drop is limited to 300 units.

Comply Foam Tips & More

To help you find the perfect fit, the Advanced Sound M4 comes with a whopping 10 pairs of ear tips. Along with nine pairs of silicone ear tips (six single-flange and three dual-flange), you’ll get one pair of Comply TX-400 foam tips. These deliver comfort, security, and noise isolation for long listening sessions and come with integrated Wax-Guard, which prevents wax from entering the sound port and diminishing sound quality over time.
