Bose QuietComfort 20
Despite some downsides, including a high price, the Bose QuietComfort 20 offers the best noise-canceling in an in-ear headphone and should tempt frequent travelers looking for a more compact alternative to a full-size NC headphone, such as the Bose QuietComfort 15.
Beats Studio 2013 ( Red)
They may not be a bargain at $300, but the new Beats Studio headphones are lighter and better-built, and sound significantly better than the original Beats Studio model.
They're fairly pricey, but the combination of very good sound and a sleek, comfortable design, make the KEF M500s contenders in the $300 price class.
Despite atrocious cosmetic qualities, the insanely cheap Superlux HD681 headphones have a sound that aspires to greatness and only narrowly misses the mark.
The KEF M200s sound excellent, with clean, accurate sound, but they just won't fit some ears.
Plantronics Backbeat Go 2 ( Black)
While its short battery life keeps it from true greatness, the Plantronics BackBeat Go 2 is a superior wireless Bluetooth in-ear headphone.
They've been around since 1991, but the Sony MDR-7506s are still great sounding -- and fitting -- headphones for less than $100.
They may be close to 30 years old, but the comfortable fitting Sony MDR-V6s are arguably the best-sounding headphones for under $100.
Bose SoundLink Around-Ear Bluetooth Headphones
Despite a few question marks and a high price, the Bose SoundLink Around-Ear Bluetooth Headphones are a very good-sounding Bluetooth pair that's lightweight and very comfortable to wear.
iLuv City Lights ( Black)
For around $7, the iLuv City Lights are well-designed budget earphones, but they push the bass a little too hard at the expense of clarity.
