I hooked up the card using a OTG Cable to my Lenovo K3 Note and all audio was automatically redirected to the sound card. In Android, users are not provided a comprehensive control panel to select audio in/out devices and few applications can detect the presence of multiple audio adapters and provide the choice to users. Hence, the USB device becoming automatic default is a nice touch. I used a Coloud Headphone to test the audio output and was pleasantly surprised with the volume and fidelity of the audio. Sound was loud, and slightly clearer but less punchier than the on-board sound.
I hooked up the sound-card to a Asus Laptop running LinuxLight OS and it was detected as a "C-Media CM108 Audio Controller" and installed automatically. I was able to configure the default audio-device as the USB sound-card and the sound was definitely an improvement over the on-board audio but on the lines of performance on the Android Phone.
I hooked up the sound-card to a Acer Laptop running Windows7-64bit OS and it was detected as a "USB PnP Sound Device" and installed automatically. I was easily able to configure Windows to use the USB sound-card as the default input/output device and run some more tests. The playback continued to be similar to Android and Linux. The audio-recording mode only supports 1-channel microphone input with Auto-Gain-Control. When I recorded blank signal (no microphone connected), I noticed that the signal was at -60 dB. This means that the sound-card is generating some electrical noise. While it is not noticeable and will have zero impact on voice-conversations using Skype etc., it is certainly not usable for recording music.
A few disadvantages that I think need to be rectified:
1. The sound-card has a bright red LED that blinks non-stop and it quite a distraction. De-soldering it would not only remove the distraction, it will also probably save 20mA current. The manufacturer could have used a smaller LED and added a current limiting resistor to reduce brightness.
2. The sound-card does not support the TRRS connector to support headphones with built-in mic over a single EP connector. You must use a headphone that has a separate pin for the mic. Audio input is also at Mic level and not line-level. Audio input is also restricted to a single channel at 44.1KHz or 48KHz.
3. The sound-card does not support Loop-back audio after-all. Or even if it does, I have missed seeing it.
4. The sound-card can easily end-up blocking adjacent ports. I wish it came with a small extender cable that would allow access to the other USB ports.
The product also arrived damaged. There was no damage to the shipping or even the packaging. I can only assume that it was damaged at factory or at another re-packaging level in India. While I could fix it, I will certainly advise users to check the sound-card ports before using it.
Not for Headphone, Earphones . The amplified output form USB sound card might damage Earpeice/headphone or heat up quickly.
This is not for Music Lovers, cant control the output even if you lower the volume to 0.
Pros: 5V Power Buildin amplifier is good.
Pros: Auto Changes to primary audio device/recording device
Cons: Poor record or no record
Cons: Definitly Not for Headphones
RESULT: I wouldn't bother buying this if i have no issues but if you want a mic out/in for you laptop because most laptops have the one input than go for it.
It doesn't do anything to the sound in fact in some minor cases it actually reduced the quality drastically for me.
Very flimsy but look at the price what can you expect.
One of the worst products I have bought from Amazon. People, don't buy this product or any other quantum product. They are not worth the money you spend. This sound card produces nothing but distortions.!!! No amplifier or nothing. Very poor sound output and chances are that it might very well damage your device. NEVER BUT QUANTUM PRODUCTS.!!! I also bought a quantum keyboard recently and found that the keys are not as printed on them. There are many sound cards out there that are worth the money.
The seller does not have any return policy. That means that you cannot return this item. This is just a useless product.!!
