A possible price mistake, BuyDig offers the FiiO E1 Headphone Amplifier (pictured) bundled with a Lexar 64GB JumpDrive S23 USB 3.0 Flash Drive in Black, model no. LJDS23-64GASBNA, for $9.97 with free shipping. (The jumpdrive will automatically add in cart.) That's $34 under the lowest total price we could find for these items purchased separately. The headphone amp is designed for iPods and iPhones with dock connectors and features a frequency response of 10Hz to 80kHz. The flash drive features read speeds up to 100MB/s and write speeds up to 55MB/s.
