The E07K is a remarkably well-built, well-thought out headphone amplifier from the folks at FiiO. It features sleek industrial design, anodized aluminum enclosure, simple, intuitive controls, and a bright, easy to read dual-color OLED screen.
The E07K can be used as a high-quality USB plug and play soundcard for PC or Mac, but it isn't tied to the desktop. It features a 3.5mm analog input and 1200 mAH rechargeable lithium ion battery for complete portability and over 20 hours of operation between charges. A full compliment of settings including EQ, bass boost, and sleep timer let you customize the E7 to exactly your specifications. Dual 3.5mm outputs let two listeners plug in headphones without a splitter.
The best part? The performance from this amplifier is unbeatable, and will add clarity and volume to any listening session. Top quality parts were used throughout, including a 24-bit/96 KHz DAC capable of wringing every bit of performance from hi-res downloads.
A full compliment of accessories rounds out this incredible package, including a USB to mini-USB cable for charging, a 3.5mm male to male cable to plug into a cell phone or MP3 player, and a robust rubber band to strap the E7 to your portable device. Keeping the E07K in tip-top shape is no problem, either, because it also includes a rubber case, clear screen protector, and velour carrying pouch with snap.
