Insignia 3.5mm to 1/4" Headphone Adapter- Only at Best Buy

I bought it so I could use my headphones with my Casio Keyboard. It was average. You kind of have to twist it here and there to get the static sound to go away, and to get the full sound in both ears of your headphones/earbuds. I returned it when I found a pair of headphones that came with a jack. Much better off than buying this product. But if you just need something quick and cheap, and sound quality isn't your priority, then this will work just fine.

This works adaptor works ok. My experience with this adapter has been subpar to what I'm used to working with. If you're going to have any movement of your cables while using this adaptor then this device is not for you. If it is in a more stable permanent setup then this could be the lowest valued option for you.

A great little gadget to make old tech accessible to current tech. Came across an old keyboard in storage that still worked and sounded much better than I played. None of my current headphones fit the audio jack. This little adapter brought peace and quiet to my family while I played away.

Very poor quality. When I used this adapter, it caused a crackling sound in my headphones. The left speaker would go in and out. Sometimes, when I rotated the adapter, it would start to work. Not worth returning to the store. Threw it away and ordered a completely different brand.

I tried this adapter between Sennheiser HD600s (Headphones) and a Schiit Magni (Amplifier). The results were bad. The connection at the both ends is out of spec and the result is an easily breakable and poor sound quality connection. I don't recommend this connector.
