• Offers a fast and easy way to connect stereo headphones

This Headphone Adapter allows you to connect a standard headset to your device. This adapter will convert the 3.5mm headset jack into a standard 2.5mm port.

Probably has nothing to do with the product, but when I tried to use it with my old earphones that I used to use with my Nokia product, one side didn't work. So, I think the wiring is different between Nokia and my new iPhone.

Physically the item seems to connect properly, however I experienced considerable static via a set of wired earphones. Moving the connections around eliminated the static. This problem is consistent but I could not determine if this problem is unique to my unit, or a general issue, or an interaction with the headphones I am using. The headphones are probably not the source of the problem - they work well in any other device, they are Bose earphones.

When I used this connector, it damaged the Headset/microphone socket on the Iphone. I suspect the IPhone end of the adapter is too long for the IPhone's socket. The first use of this adapter resulted in the immediate failure of the IPhone's internal speaker circuit (the private listening speaker). I had to use the room speaker to hear my calls. Apple replaced the IPhone under warranty. This adapter is NOT compatible with the IPhone!

This does what it is supposed to do - it allows me to use a standard wired headset with my BBerry Curve. I just keep it in case my bluetooth runs out of juice, and have only used it a couple of times, but can't complain. (I also can't get too excited about an adaptor either, hence the 3 stars.)

Like the title says, this thing only plays audio through one speaker. So, it's probably good enough for phone calls, but useless for listening to music. It should really say MONO somewhere in the description.
