If you've always wanted to own a pair of high-end "audiophile" headphones but can't quite justify dropping a grand on a pair, the superb sounding HiFiMan HE-400i is a good compromise.
JVC HA RX900
The JVC HA-RX900 is an excellent over-ear model that will impress listeners shopping for a low-cost headphone to use at work or in the office.
Sennheiser HD 202 II
If you're on a strict budget and can't spend more than $40, the Sennheiser HD 202 IIs are a worthwhile entry point for aftermarket cans, boasting a comfortable fit and the company's excellent signature sound.
Bowers & Wilkins P7
The Bowers & Wilkins P7 may not the best headphone you can buy in its luxury price range, but it certainly is among the best, with excellent build quality and rich sound that works well with a wide range of music genres and sources.
Sol Republic Master Tracks (Gunmetal)
The Sol Republic Master Tracks have a distinct, eye-catching design and good performance, offering better, more refined sound than the original Tracks.
Beats Studio Wireless (Black)
While it'll cost you a hefty $380, the Beats Studio Wireless is an excellent wireless Bluetooth headphone.
Beats Studio 2013 (White)
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.
Sony MDR 7506
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.
