VAMP Integrated Headphone Amp, DAC and Battery Pack for iPhone 4/4S
Spy-worthy gadget for the modern audio connoisseur ushers in a new era of pure sound, sophistication and power. VAMP features a 150mW x 2 amplifier, dedicated pure Digital-Analog-Convertor, VQ audio enhancements, optical audio output and backup battery all integrated into a solid metal case that transforms an ordinary iPhone 4/4S into a sophisticated and stylish high fidelity device.
Powerful Amplifier
A 150mW x 2 amplifier bypasses the iPhone's internal amp designed for smaller, low-impedenance ear buds and provides optimal power to drive even the most demanding and high-impedance headphones*. VAMP's rotary volume knob allows you to finely adjust the volume and its hi/lo gain switch adjusts the output level to match the power required for both low and high-impedance headphones.
*High-impedance headphones and professional / studio headphones require or benefit significantly from a headphone amplifier
Pure Dedicated Digital to Analog Convertor
VAMP's dedicated DAC extracts the iPhone's digital output and converts it into its analog form for the purest and unparalleled audio listening experience.
VQ Audio Enhancement
VAMP offers two, selectable, audio modes for the discerning audiophile.
PURE mode (indicated by the red light on the LED toggle switch) outputs audio in its original form
VQ mode (indicated by the green light on the LED toggle switch) adds a slight spatial 3D soundstage, tightened bass and increased treble attack that invigorates an all around sensory experience
Optical Audio Output
A S/PDIF/Toslink digital audio output transforms the iPhone into a high fidelity source (optical cable sold separately).
Maximum Battery Vitality
A colossal 2200mAh lithium-ion battery provides up to 8 hours of playback. In a flick of a switch, the battery can serve as a backup power source and double the iPhone's battery life.
Brushed-Metal Case
Aircraft-grade brushed metal and shock absorbing silicone shields the iPhone from dents, breaks and scratches.

This is for powering larger headphones and for being deaf at 30…..
All I can say is nothing like adding a 5lb brick into your pocket.
A nice concept, but $650 is too pricey. You could get a high-end compact audio system such as a Bose for that price.
Of course, the ultimate irony is that getting digital S/PDIF audio for purposes of 'audiophile' high fidelity is totally compromised by the generally low quality of the compressed mp3 audio that gets downloaded onto these devices.
If the main purpose is just to get louder volume, plug in a micro-plug and drive a lower-cost external headphone amp using the analog signal.
I think it's user error……. 🙂
Where are you seeing them… You should get one on the notification bar and when you go into the app you should see the red box with the count
I would Uninstall and reinstall….
