Using a OP Amp the AP001 is able to deliver powerful audio amplification and bass enhancement, without much coloring or distortion to the original audio signal.
The AP001 was designed with portability in mind, its light weight 15.5g body houses a 120mAh battery that will also for over 12 hours of continuous use.

As I said there are no buttons on this amp, it automatically powers on and off in response to music. When it is on there is a blue light in the middle and when it is plugged in and charging (with a basic micro usb) there is an orange light on that shuts off when it is finished charging. This little guy has a fairly long battery life and about 2 hours of charging gives it around 10 hours of music playing. It's well built I haven't noticed any scratches or damage to it despite a fair amount of use thus far. If I had one improvement I would add a little slot onto the amp or a clip on the back so that it can either be hung or clipped to something.
The cable that comes with this is TERRIBLE. I believe I received a defective one....if not they are very poorly and cheaply made. I am still waiting to hopefully receive a replacement from MP4NATION though I have not heard back from them yet and will be back to raise or lower the star rating depending on whether or not I hear back from them. The cable sends very loud static though the amp and headphones whenever it is touched or moved and makes the amp unusable with the included cable so I have been using my own.
As stated this is a one feature amp, there is no neutral or mid boost setting. It also does not come with any instructions at all so that should be a sign of how basic the amp is. Just a plug in and listen. I greatly enjoy this amp and the simplicity of it and I love the something extra it adds to certain headphones.
UPDATE*** Okay so I returned this amp awhile ago for a whole new replacement and the cable that came with the replacement was equally as bad so the cable is just very cheaply made. I splurged on a short cardas cable found here CARDAS HPI Audiophile Interconnect Cable Adapter Male 1/8" 3.5mm TRS Mini-Plug that can be used with any amp and the cable fixed all problems with static, any distortion etc. Overall I give the amp 3.5/5 because the cable really needs to be changed.
Then i press the button :-D , and after a few days the package arrived with no problems, i must to say that this item it is not for people who listen music at low levels, this little BEAST is awesome, i use it with my Moto G 2 Gen, with my 250 usd laptop and with mi rMBP Late 2013, and the amplifier works PERFECT! with all of them! i have no complains about it.
It is a really good investment.
I have used this on my Galaxy S5 smartphone, and my Nexus-7 tablet PC with amazing results. I really thought it would have been more convenient to have an separate volume control, but as long as you have a volume on the source device, another volume control is not needed. The addition of the volume control on the amplifier would require the amplifier to be significantly larger and more expensive.
I have used it for several weeks with my new Sennheiser HD DJ 8 headphones which are absolutely perfect, so that biases my experience. This is an extremely minimalistic amplifier, without any buttons or dials at all, which can be nice if you're going to have it in your pocket a lot anyways and would rather control your audio from 1 source (namely your smartphone or ipod.)
Overall I have no complaints other than the incessant follow-up emails the parent company for this product sends you, hounding you for reviews and feedback. This is couched as customer service, but it strikes me as more than a little unprofessional.
