CHISNLY Audio Adapter

I just bought this yesterday, so this is a quick first-impressions and technical notes review, NOT long-term or rigorous evaluation. All of the described testing was conducted on Mac OS X. I plan to hook it up to a Linux system later.Size: It is very small — it's just about the same size as the typical pair of audio plugs you're going to plug into it. However, it is still too big to fit into USB ports adjacent to other plugs in either direction, so if you have that situation, you'll want to get an extension cable. The dimensions (excluding the USB plug) are: 24 cm wide, 27 cm long, and 12 cm thick. Despite looking red in the product photo, the microphone jack is correctly color-coded pink.LED: The activity LED is green (not blue! hurrah!), located in the middle of the right edge (close to the "h" of "tech" in the logo) and shines through translucent plastic. When the adapter is plugged in, the light is on solid; when it is in use it FLASHES RAPIDLY, about 5 flashes per second. This may be very distracting if you are not in a brightly lit space and the adapter is in your field of view. However, it could be mostly obscured by a piece of tape, velcro cable tie, etc. And I do appreciate that it indicates whether it's in operation or not, which could be useful for troubleshooting.Firmware: The device's name as shown to the computer is unfortunately "USB PnP Sound Device", which seems to be a chipset default. This means that if you use another audio interface that uses the same chipset and also didn't customize the name, you will have two audio devices both named "USB PnP Sound Device", which can for some applications make it hard or impossible to select the right device.Sound output: Output is fairly loud even at low system volume; you may want an inline attenuator (volume control). (Tested with 64 Ω over-the-ear phones, and a basic headset, so far.) I haven't noticed any particular issues with the frequency response etc. but I'm not a picky listener.Sound input: Seems fine. Only tested with a basic PC headset so far and anything I said about the audio characteristics would be more about the headset than the adapter.Final score: I'm giving it 4 stars out of 5 because while its performance and price are fine, the blinking LED and generic USB name may be key issues for some users.

Some object got in my headphone jack on my MacBook Pro while it was in my back pact. I tried everything to get it out short of taking the computer apart (which I was not going to do). I use my Mac primarily for music recording and editing so the headphone jack is a very essential part. After doing some more research online I came across these USB adapters and to be honest I was a little weary of them. I looked through several of them on Amazon and never having used one or know someone who did I was taking a shot in the dark when I ordered this one. I've had it about 2 weeks now and I am very satisfied with it. I have not detected any noise and the quality seems to be very good. I have not used the microphone input so i can not speak about it. I am extremely pleased with this adapter. If it starts to fail I will update this review but as for now I would highly recommend it to anyone who needs this kind of adapter.

This thing saved me from a costly repair. My headphone jack on my lap top wasn't working and music and sound would cut in and out and I had to plug my headphones in just right to get it to work. Got tired of that so I bought the Sabrent USB adapter but when I got it the volume was super weak and the sound quality was bad. Bought this a day after using the Sabrent (got fed up with it) and this one is plenty loud and the sound quality is fantastic! It's even louder and sounds better than the original jack and now I have to actual turn my music down a notch. It's loud in a good way, not distorted loud. The bass boost actually works really well and so does the surround sound. If you're headphone jack broke spend a few more dollars and get this!

My daughter asked me if I could fix her computer, she had a broken headphone pin inside the plugin. I tried the super glue route, but no luck. So I began asking questions and I found this little baby. It does exactly as they say it will, plug it in and just sit back and it uploads everything I didn't have to do anything, and then I plugged my headphones to my daughters computer and wow how the sound was so much better. It was 10 times better than before, this little baby packs a punch when it comes to your sound. I liked it so much I bought another one for my computer and I don't have a broken headphone pin stuck in mine. I bought and got it quickly, you won't go wrong with this product.

NRG Tech External USB Stereo Audio Adapter - This product did not last more than 72 hours with normal usage.When it was working it was fine though the sound quality running through was a little static at times and adjusting the sound levelwas very sensitive. My biggest frustration is that I used it three times - I had to switch it out between two machines and one time during the removing it from one machine it came apart in my hand into two pieces. So guess I will not be trying this one again.

At some of my customer's location I need to do follow up training on their equipment. The computers used with the equipment do not have sound cards or on board audio outputs. This adapter solves the problem of not being able to the the audio portion of the training. I highly recommend anyone who does on site training to pick up one of these adapters to keep with them encase they run into the same problem. A quick and inexpensive solution for a problem.

The NRG soundcard uses a stereo connector with the ring biased for electret microphones. There is not a separate isolation resistor passing bias to the tip, so if you use a truly monophonic microphone connector, the ring shorts to the shield and the bias voltage is grounded so that no bias is supplied to the electret element. They should have used 2 resistors, one for the ring and one for the tip to avoid this design flaw. It is useless with a monophonic microphone connector.
