Valefod Stereo Audio Adapter 6.35mm (1/4 inch) Male to 3.5mm (1/8 inch) Female Headphone Jack, 5 Pack

Does the job well and is good value as well as being solidly built. Can't ask for much more. The 3.5mm socket is fairly tight but actually I think that is a positive not a negative.

I bought this for when I'm playing piano as my earphones won't fit into the keyboard, and it's been super useful enabling me to play late at night without making too much noise. Love it.

They grip the plug very tightly which unsettled me at first but they seem to be fine but note I'm not taking plugs in and out very often so I can't speak for regular use like that. But in situ they are working very well

Good

These do the job and the unit cost was excellent. Sound quality was more than acceptable for most uses, I couldn't perceive any degradation; though would I include these in an audiophile solution? I don't know

They do the job, and as a perpetual losers of these things, having a few of them for cheap in one go is a necessity!

Does the job but is not the best quality

What you get is the gold plated things. Nice, but sadly not going to output much bass or going to line up perfectly with the bands with a 1/4" jack. I lost my other ones (two black in picture) then found them again and when producing music I was using these for a while. I was convinced there was something wrong as I only heard half the audio frequencies and it made listening back when mixing and mastering pointless.Don't use on instruments, you may risk shorting the jack circuit and making future use unusable.
