Ultimate Ears 300 Noise-Isolating Earphones

Big bottoms? We got ’em. Does a deep, thumping bass get your blood pumping? The Ultimate Ears 300 Noise-Isolating Earphones are the choice for you. Ideal for listening to hip-hop, house and electronic (or for anyone who likes a little extra low-end in their music) the 300s are tuned with extra bass for deep, thumpin’ beats.

Ultimate Ears 300s feature a sleek, black and orange design that sits flush with your ears, for a stylish look that’s comfortable and unobtrusive. The shapeable ear loops can be worn over the ear for a secure, customized fit when you’re jogging, biking or at the gym. The materials are made to resist sweat. And the tapered silicon ear cushions fit more naturally than traditional “square” ear cushions.
