The E17 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 E17 can be used as a 96K/24-bit USB plug and play soundcard for PC or Mac, but it isn't tied to the desktop. It features 3.5mm analog input as well as a digital input that accepts mini-toslink or 3.5mm digital coaxial cables - adapters are included to make sure that you can use full-size digital connectors, as well. A 1500 mAH rechargeable lithium ion battery ensures complete portability and up to 15 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.
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 Texas Instruments PCM2706 USB receiver, Wolfson 8740 DAC chip, and amplification by ADI AD8692.
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 E17 to your portable device. Keeping the E17 in tip-top shape is no problem, either, because it also includes a clear screen protector and velour carrying pouch with snap.
