1. Klipsch X10i Headphones for iPhone

The Klipsch X10i ($350) headphones offer premium comfort and sound quality, albeit at a premium price. The X10’s are one of the smallest and lightest full-featured headphones currently available for the iPhone. They weigh in at a light 10 grams and come with 5 different-sized sets of Klipsch’s Countour ear gels (3 sets are double-flanged). In terms of sound reproduction, the X10’s perform well across the spectrum with an especially meaty low end. The silicone eartips offer a tight, snug fit, and provide passive sound isolation. The headphones come with a quarter-inch adapter for non-iPhone and iPod music players, an airline adapter, a cleaning tool for ear wax removal, a faux leather carrying case, and a small pouch carrying case.

2. Etymotic hf2 iPhone-Compatible Headphones

While many headphones are tweaked to be bass heavy, the Etymotic hf2 ($155) headphones are designed to deliver precision sound quality. With equal parts low, mid, and treble, listeners can discern the sizzle of high hats as well as the growl of the bass guitar. The hf2s come with 2 different-size sets of triple-flanged silicone eartips as well as a set of foam eartips that many people who have trouble with in-ears seem to gravitate to. The hf2 earphones sport a 4-foot cable that comes with the requisite microphone and call/music control button. Included accessories are a filter cleaning tool (for earwax), an extra set of filters, and a carrying case.

3. Klipsch S4i

The Klipsch S4i ($99) are part of the still rare class of iPhone-compatible headphones that include volume controls along with a microphone and call/music button. The headphones are made from a black glossy plastic with chrome accents that goes perfectly with the black iPhone 3G and 3GS. The S4i’s sound reproduction is bass-heavy but not overbearing and should please fans of modern pop music. The Klipsch S4i’s come with 3 sets of rubber silicone eartips, a cleaning tool for earwax, and a carrying case.

4. V-Moda Vibe II Headphones for iPhone

V-Moda knows how to build stylish headphones, and in this area, the V-Moda Vibe II ($120) don’t disappoint. Made out of stainless steel and available in two colors (black and rouge), the headphones have a two-tone design and a X-shaped framework that fits over the earbuds. In terms of sound, the Vibe IIs are tilted toward a powerful low end. The headphones are a step up in terms of sonic clarity of the previous generation of V-modas, but not quite in the realm of premium headphones. The Vibe IIs have a durable design, with its stainless steel earbuds, fabric-covered cord, and bendable headphone plug that prevents cracking from repeated used. Included with the earphones are 4 different-sized silicone eartips as well as special earhooks that give the headphones more stability for use in sports activities like jogging. Also included is a stylish leather carrying case.
