This product is suppose to allow you to charge your phone wile listening to music with your ear buds. However, a distinct HUM comes through the ear buds when playing music and charging. If you remove the charging wire, the hum goes away and you can listen to music just fine. I reported this before and the vendor sent me another unit. However, this one also had the HUM. So the issue is clearly a design flaw and the unit simply does not work without making the hum.

I used it in the car. I plugged it in the cigarette lighter to charge the phone and with another wire plugged it in my car radio and I could hear the HUM. When I removed the charge wire, the hum went away.

I would NOT Recommend this product, unless you like hearing a HUM with your music while charging the phone.

Thank you

Buy HTC 3-in-1 USB Audio and Charger Adapter for HTC ExtUSB Smartphone Now

I like my G1 but for the fact that I can't use standard headphones, and for that matter, that I can't charge my phone while listening to music. This little gadget provides me the functionality that should have been in the phone. There was another web site with a similar device selling for $20.

It works great. Someone mentioned the problem with the music port; I wonder if it's his cable rather than the device, as I have no problem. I even tried wiggling the cable around and didn't hear any problems.

So, a cheap little device that adds a lot of value to my phone.

Ordered not sure if it would work or not for my mytouch phone, as I heard someone had an issue with it. Figured 8 bucks was worth the risk, and it was. Works flawlessly, I can charge my phone while streaming music in my car to my stereo using a 3.5mm audio cable.

I have a Touch Pro, which comes with a different adapter that is nearly as long as the device itself. The cable is also rigid, which makes it look ridiculous when using it to listen to music on headphones. More problematic, it's prone to bumping and damaging the delicate ExtuUSB connections on the phone.

I bought one of these adapters to address those concerns while listening to music. With the flimsy cable and smaller adapter box, it doesn't look idiotic and is not as likely to catch on things. It comes at a price, however. There seems to be little to no electronic filtering, so if you simultaneously plug the adapter into headphones (or an auxiliary cable or tape adapter)and an external power source (such as a power adapter, PC USB connection, or car power adapter), you will hear a lot of static.

So I keep the standard adapter on hand for when I'm driving or working and listening at a PC and this adapter for when I'm active and listening. Actually, I have multiples of both spread around my home and workplace, because they're so easy to lose or forget.

Thank goodness HTC intends to include 3.5 mm jacks on all future models.

The product works well and the shipment was fast.

I recommend it.

The best price.

I'm using it on my HTC TYTN.
