Sennheiser CX 5.00I iPhone 用入耳式耳機

Finally got these in-ear headphones and the bass response really surprised me for such a small package—crisp, deep, and not muddy at all. They fit snugly in my ears even during a long walk, which is a nice bonus.

The in-line mic works flawlessly for calls, and the sound is so crisp that I'm catching instruments in songs I've heard a hundred times. The bass has real punch without drowning out the mids, which is rare at this price.

I've been using them daily for over a month now, and the clarity on acoustic tracks is something I haven't heard from other buds at this price. The fit is snug enough for running without falling out, which was a pleasant surprise.
