D1 DAC
The D1 uses the ESS ES9018 DAC, which is well regarded for its low noise and high fidelity. Due to the high signal-to-noise specs of the ES9018 and the added benefit of double redundancy power source conversion and filtering, the D1 presents impressive low noise and low distortion characteristics. The D1 can process digital audio at any bit depth up to 32-bits and any sample rate up to 394kHz
D1 Headphone Amplifier
The D1 includes the ES9601C SABRE headphone driver amp with circuit protection and is designed for a wide range of headphones that will satisfy even the most critical listeners.
D1 Power
The D1 is powered directly from the USB input and passed through two stages of regulation to ensure no USB power variations affect the audio quality. Because of the efficiency of the D1, it can even be powered by a phone or tablet.
D1 Preamp
The audio line-out preamp connects to powered speaker systems, amplifiers, or other external decoders with an analog or optical output.
D1 Volume Control
Volume for headphones and line-out is controlled directly from the D1 front panel via the digitally-controlled analog potentiometer. Smoothly adjust volume levels at fine increments without any undesirable noise or channel imbalance at lower volumes.

Cute! Didn’t last long for me
Color: A-Pink, Color: A-Pink
Very cute and comfortable! Love the folding tabs. Unfortunately, I’ve only had this case for around 6-7 months, and it’s already cracked and chipped. I also always carry it in a protective case (aside from this one; a computer sleeve) so i don’t think i was being rough with it at all. Still works fine, and should protect the ipad. i’m just sad it cracked so soon! I would’ve kept it for much longer had it not. I do however take it to school/work everyday, so it did commute with me.

Fits the new iPads. Buttons are easily accessible.
Color: 1-Navy Blue
Fits the new iPad. Buttons are easy to reach, and it protects the screen with a soft fell back. Easy white clean vinyl on the outside. It has open vent spots so your device can cool. Slim and sleek. A great value for the money. Buttons are easily accessible. High-quality.

Perfect, it fits like a glove.
Color: 1-Navy Blue
I really liked the sleeve, the navy blue color looks very elegant and the material feels resistant but soft to the touch. What I like the most is that the back is translucent, so you still see the design of the tablet.
It works great for watching videos because it stands firm when folding it, and turning off the screen alone when closing it is very practical. Because of the price it has, the quality is excellent.

Great Protective Case for My Mother’s iPad
Color: 2-Watermelon Red, Color: 2-Watermelon Red
I bought this case along with my mother’s new iPad, and it was the perfect choice. The watermelon red color looks beautiful with the pink iPad and gives it a very clean and stylish look. The case feels sturdy without adding too much weight, which makes it comfortable for her to carry around and use every day.
The stand feature works really well for watching videos, reading, and video calls. I also like that the case supports the auto wake and sleep function, which makes the iPad feel even more convenient and easy to use. The cutouts fit perfectly, and Touch ID still works without any issues.
The translucent back is a nice touch because it still lets the iPad color show through while keeping it protected from scratches and bumps. Overall, this case exceeded expectations and makes a great addition for anyone wanting both protection and style for their iPad.

Good product. What you see is what you get.
Color: 1-Navy Blue
Material feels sturdy and was a perfect fit compatible for my iPad. There's adequate grip and padding for a comfortable yet slim feel. Magnets hold it close and in one position when propping it up for watching landscape videos. Back is translucent as advertised. Solid product, put it on as i opened my new ipad for immediate protection. Perfectly safe blind buy if you're also getting that 'frequently bought together' suggestion from Amazon.
