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.

I "rescue" old Thinkpad laptops off ebay to install Linux. I bought two of the GMYLE 2-Port USB 2.0 cards for two IBM Thinkpads Model R51 (introduced in 2004). They are simply plug and play under PCLininuxOS (KDE_2013.10) and a dual boot with Windows XP with SP3. Driver CD was not required; although Windows made a big deal via a number of pop-up notices; "new hardware found", "searching for drivers"...yada-yada.In both laptops the card was any easy install, they sit flush with the case, and have remained firmly engaged.The ports accept and power the several USB thumb drives (2GB-16GB) that I tested with only one issue under Windows XP which required me to reinsert the thumb drive a couple of times.The combination of the two ports would not power an external hard drive (320GB WD in a Rosewill RX81U-25A enclosure) with a USB "Y" cable. However, with the addition of the supplied USB power cable from a third USB port to the center connection on the card the external hard drive worked well enough to make transfers. It's good enough for my purposes.Having the extra ports allows for more options such as a wireless mouse, an external card reader, and in the case of a friend; a USB dial-up modem to use with Linux.I'm very pleased with these cards!UPDATE* (December 2014) More goodness! I moved a card to a recent ebay purchased Thinkpad T400 running Windows 7 Professional 32 bit; installed card and drivers were found on reboot. Now there are two extra ports; tested with a usb Logitech wireless mouse and usb cabled Canon printer.

5/4/15 Only 1 star because it did not work for me. I have an IBM Thinkpad 760 running WIN98 SE, this is not my only computer, but I keep it for legacy software that does not respond well to WIN7 compatibility mode, or to Linux WINE. I am an experienced computer user for over 20 years. I was hoping to use this for jump drives and a mouse but I never got the chance. It simply was not recognized as existing or working, might have just been doa. The drivers downloaded and updated fine but to no avail. I also searched for other drivers on line and tried a few but no joy. So if you have a WIN98 SE computer it may not work as indicated elsewhere in the reviews and answered questions, or once again it may have simply been doa I did not try a replacement.
