    Exactly what I was Looking For
    I have a unique application where I needed to use mono earphones with stereo cell phone headphone adatpers for audio monitoring via cell call. This is exactly what I needed... and works great. Thanks Monoprice!

    It works!
    To maximize the shipping fee involved, several small items were purchased at the same time. This adapter (7160) is the only one that is required and it works. 7129 didn't work out.

    PROS: At 21 cents, it's a bargain if the shipping fee is not excessive.

    CONS: None so far!

    Works but not without hassle
    This items takes a mono signal from a 3.5mm male and turns it into a stereo signal (same on each channel). The female end on this adapter is very loose however. While you can Jerry rig up a solution you shouldn't have to be doing that in the first place. I was unable to find another product from another company so looks like you'll have to make due if you need this type of adapter. ( I'm using it to take a mono lav mic and changing it to a stereo signal before it goes into the recording device... Less work in post/editing)

    PROS: Changes signal as intended

    CONS: Poor Tolerances (loose female connection)

    Some problems with this device...
    I got this, and it wasn't working at all, so I got a replacement.

    I got the new adapter, and it wasn't working either. However, I figured out what the problem is.

    This product DOES NOT work with any earbuds/headphones that have an integrated microphone/remote. These types have 4 bands on the plug, instead of 3. These appears to be an oversight on the manufacturer of the adapter, since it should be able to easily work with either 3- or 4-banded plugs.

    Also, the technician I spoke with said that the mono output would come through both channels... this is wrong it only comes through the LEFT channel.

    PROS: Cheap, kinda works...

    CONS: See review

    quality issues
    very cheaply built. 3.5mm mono connector doesn't make good contact inside and is loose. i've never had any good luck with audio adapters from monoprice. they seem to be all made this way. monoprice, you should consider pulling these items from your site.

    PROS: price

    CONS: quality

    No Quality Control / Bad Design
    I had read the reviews and knew I was likely to have a problem so I bought two 7129's and two 7160's thinking I would get at least one part that worked without intermittent connection. No such luck. All four parts had the same problem as detailed in other people's reviews. These are sealed units so you cannot try to bend or adjust anything. It seems a flawed design to begin with. The ring connection has no spring contact so you are just hoping that it will lay across the metal hole well enough for the jack part to make contact. Well mostly it does NOT. The have no quality control and should not be sold until the design and manufacture is fixed so that they actually perform their function without requiring you to hold them in your hands to make the connection.

    PROS: None

    CONS: Intermittent Connections require you to hold device in your hands during entire service of operation.
