    2.5mm Mono Plug to 3.5mm Mono Jack Adaptor
    Used this along with 3.5mm adapter and stereo cable to adapt the length between a logitech 900 RF base and mini-blasters. Works great.

    PROS: Good price. Good Quality.

    CONS: None.

    Excellent Harmony IR adapters
    I needed these so I could extend the Harmony IR Blasters into another room. With this adapter, i was able to use readily-available stereo headphone extension cable, rather than seeking 2.5mm mono coax to go from 1 room to another. They work great!

    PROS: Perfect fit - no added cable length.

    CONS: None

    Works perfectly with Harmony Hub
    If you have a Harmony Hub and want to use standard IR emitters versus the Logitech broadcast emitter you need this adapter.

    Great for using most IR targets with Slingboxes
    This is a great product at a great price. We have a project at work where we are using 150 Slingboxes. I don't care for the IR emitter eyes that come with the Slingboxes but they are 2.5mm and most 3rd party IR emitter eyes are 3.5mm. This was a great solution for utilizing 3rd party IR emitter eyes with all Slingbox models.

    ridiculously low price, free delivery, quality product. MonoPrice remains my goto vendor for a/v an pc cables/supplies.

    Work great with the Harmony Hub
    I got a couple of these to use remote extenders with the Harmony Hub and they work great.

    Exactly what I needed to extend Harmony IR min-blaster
    I purchased this adapter, along with a 3.5mm to 2.5mm adapter for the other end of the extension cable, and both worked perfectly. My order was confirmed, shipped, and arrived right on the schedule promised. Not only is Monoprice one of the few places you can even find these adapters anymore, i am amazed that they sell them in singular quantities and ship so fast.

    Great little adapter
    I used this adapter to convert the IR blaster ports on multiple Logitech Harmony remotes to something a little more standard. Most IR blasters and kits are all 3.5mm and Logitech decided to make their jacks 2.5mm. This adapter worked perfectly in every instance it was very affordable.

    PROS: It feels somewhat durable. It works.

    CONS: None
