Entry-Level IEM for Sports & More

Quickly gaining popularity on Head-Fi for its excellent value, the Alpha & Delta D2 IEM is made for active listeners who like to bring their music along for runs, hikes, gym sessions, and more. Each earpiece is shaped to sit flush against the ear for long-term comfort, and the flexible memory wire ensures a secure over-the-ear fit while you move. The sturdy construction is rated IPX4 for sweat and moisture resistance, and to keep you motivated mile after mile, the balanced sound signature features lots of punchy bass. Finally, a full suite of accessories—including 8 pairs of ear tips—ensures you’re ready right out of the box.

Note: At checkout, you’ll have your choice between the D2 (base price) and the D2M (+ $4), which is the same model with an inline mic.
