Logitech Ultimate Ears 500 Noise-Isolating Earphones - Dark Silv
[985-000080]

If you have 60$ and you want one of the best in-ears i've ever tried (believe me, a lot), just click the "buy" button cause you wont be dissapointed.
They work perfectly with classical rock music, I mean, Dire Straits, Eric Clapton, Pink Flyd, The Rolling Stones, Queen,... as well as country music, you'll clearly hear every instrument on the track
