Josi Minea 2.5mm Male to 3.5mm Female Audio Adapter Premium Quality Converter Headphone Earphone Headset 3 Ring Jack - Stereo or Mono

The MIDI ins and outs on the UNO are (for some unknown reason, maybe they saved a penny on each in manufacturing?!?!) 2.5mm. These converters turn those jacks into 3.5mm, which means you can use "regular" mini jack-to-MIDI jump cables. Sure you get a pair of the right cables with your UNO, but it's always safer to have 1) spares and 2) more universality whenever possible, IMO. I make my own MIDI jumper cables, because I never know whether I need a type A or a type B for a given project, but FWIW the ones that work with Korg products (SQ1, SQ64, etc - the Volcas have man-sized MIDI DIN) are the ones that work with the UNO. One of these days I'll put a polarity switch on all my cables to I have both bases covered, but I digress. Get a pair and chuck 'em in your pack.

Great item to go from Microphone into DSLR for video recording

When I plug this in all the way I can only hear with one ear and I cant be heard at all by the other person when talking. If I pull it out a bit It works normally but if I move the wrong way (Because it is not stable Since it isn't inserted all the way in) It doesn't work unless i sit still and not move to mess up the connection. I have ordered a 2.5 headset instead of trying to use an adapter to try and save money.

I own a pair of Drop+Epos PC38X and they use a 2.5mm-to-3.5mm cable for input. I own other cans that use just 3.5mm so I ordered this adapter to keep in the PC38X so I wouldn't have to switch entire cables running into my DAC/Amp.. and it works great! The adapter sticks out just enough from the headphones to make it easy to plug in my 3.5mm cable. The entire adapter will pull out with the cable when disconnecting it.. so you'll either have to plug the adapter back in or just get good at holding the adapter in place with your thumb as you pull lol. To me, that's a minor inconvenience than having to switch out a whole other cable.

This product is useful for converting 2.5mm 4pin (TRRS) to 3.5mm 3pin (TRS). It does NOT fit BOSE QC 25. The 2.5mm male side is too large to fit in the female opening on the headphones. I was able to grind down the case of the adapter to make it fit and it works fine.

Photo connected with the item shows two adapters. When my order arrived, I had one. Does it work? Sound quality is not great but it's unclear whether the problem is with this adapter or the cassette player I'm using it on.

Made well and fits JBL Tune 760NC

They work.

Es un adaptador que no sirve, muy mala calidad, alejense de esto.
