I haven’t seen any headphones produced in the past 20, or maybe even 30 years that have used a 6.35mm plug. I’m always scrambling to find an adapter when I want to plug my headphones into basically any of my synths that have a headphone out.
I understand there are structural benefits from using a larger plug/socket, but aren’t these totally negated by needing an adapter in the first place?
It’s not only mechanical forces, it’s also about just sitting better in the socket and making a more solid connection electronically. I had some flimsy 3.5 mm sockets, where I had crackles, if there was some movement of the cable.
I for instance have headphones, with both sizes. The 6,5 mm jack is put over the 3,5 mm jack and screwed to the socket by a thread.
the adapter is going to make no difference at all as long as it’s a reasonable conductor.
I’d say 6.35mm is pretty standard for pro equipment isn’t it? Like - desks/guitar amps/effects usually use them.,
I wouldn’t trust a 3.5mm jack very far, they feel way too fragile in general.
i feel like all studio/DJ headphones come with a 6.35mm jack - just possibly with one you can remove the tip of to reveal a 3.5mm jack
Typically in the past 1/4” was used in pro/high end gear and 3.5mm portable/consumer gear, even today many higher end headphones use 1/4” although in the past few years for some models this has changed to the screw on adapters - most likely to tap into the smartphone market. I don’t mind either kind, but screw on adapters are pretty much a must for reliable connections so I tend to go for those myself, best of both worlds.
