SaulR26 t1_j9aw6n2 wrote

Yup, 4.4mm is the superior connection type. It's big enough to feel sturdy, it's small enough to not feel obtrusive, and it provides a balanced connection.


Xane1985 t1_j9bd1hn wrote

You might say it's "perfectly balanced, as all things should be."


AngryTank t1_j9bs9fb wrote

That’s why I prefer the unbalanced balanceness of XLR


nopunterino OP t1_j9awczy wrote

True, though I didn’t care about it being balanced for this list, it’s purely practical


ExiledSanity t1_j9b9rcl wrote

I've used 2.5 mm with my BTR5 for years and never had an issue.

4.4 is definitely better and there's no need to have both, but I found 2.5 surprisingly resilient.

Same, have been using 2.5 with my Qudelix 5k and never had any issues. I managed to get the 5k stuck while moving resulting in it falling off with high pressure on the connector and still no bends.

Yaarmehearty t1_j9jnmcx wrote

I’m not saying I don’t think it’s the worst on this list but I don’t get how people seemingly regularly break them. I have only managed to break one ever and that was by dropping an amp on it so totally my fault not the connector.

I have 2.5 on every single balanced wire I own so I can use a small adapter to plug it wherever I want. I have never bent a single one of them.

It's a non starter.

nopunterino OP t1_j9ax1vx wrote

It’s cool that it’s chunky but it does not click in place and it’s fiddly to get it upright


kerouak t1_j9b5cdj wrote

Huh your XLRs don't click in place? Mine do, theyve even got a release button on them...


LyKosa91 t1_j9bb0vf wrote

that's the female end, the male end that's used for headphone outputs friction fits. a lot of amps don't even have releases on the rear inputs either.


kerouak t1_j9bedaa wrote

Not sure what you mean. I use XLR cables to connect my monitors to my pre amp and they click in at both ends.


LyKosa91 t1_j9bf6s2 wrote

So the female end has a release button on the connector, the male end doesn't. The specific amp etc might have a locking catch but that depends. The vast majority of headphone outputs have no lock, my KRK monitors have no lock, the rear inputs on my old A30 pro had no lock, but the inputs on my singxer SA1 do.


kerouak t1_j9bg3e2 wrote

I see. Fair enough - I've literally only been using XLR for a couple weeks so just assumed what I had was the norm.


boredinballard t1_j9c05ha wrote

It's the norm on high quality connections typically. The cheap knock offs usually don't have them. Neutrik connectors usually have them, but they do have models without locking tabs.


AntOk463 t1_j9bos2w wrote

You're talking about mini XLR, not full size.


fuzeebear t1_j9ci14q wrote

Both sizes of XLR are latched, though the latch itself is on the female connector. Which is why you associate it with mini-XLR, since female mini are used in headphones quite often


nopunterino OP t1_j9b77sl wrote

oh yeah wait, depends, the one i used did't, soz


blorg t1_j9diblq wrote

He's talking about the 4-pin headphone output on the front. I think it depends on the type of the connector, to click satisfyingly it needs the notch on the top and not all do.

I have some connectors that sort of click satisfyingly but I also have at least one adapter (on the right) that is extremely unsatisfying, it just sort of goes in and there's no clear point at which it's fully in. The black one is OK and it is clear when it's finished pushing in but it doesn't "click". Only the middle one clicks.

I don't think I've ever seen 4-pin XLR headphone outputs with a physical release button. That's for the interconnects at the back.


AntOk463 t1_j9bol7q wrote

That's why you get headphones with mini XLR connector and use a mini XLR to 6.35mm to make you feel even cooler.

Every time I plug or unplug the mini XLR cable from my AKG while I'm wearing them, I imagine myself as Tom Cruise in Mission Impossible Fallout when he connects his oxygen in an identical way. Even cooler because you need to press the button and makes you feel like you are doing something serious.


hfcobra t1_j9c9845 wrote

XLR is S tier because twice the power double the fun.


blorg t1_j9din6c wrote

It's typically double the voltage, which is four times the power, unless there is some other current limit in the amp (which there often is).

4.4 (top) and 2.5 (bottom) in this picture are also balanced and double voltage.


hfcobra t1_j9dljs4 wrote


Not sure where you get 4W=2VxA


blorg t1_j9dw8zp wrote

For a constant resistance as voltage increases current also increases proportionally (Ohm's law, I=V/R).

As current also increases proportionally, the increase in power is the square of the voltage increase.

It's also the square of the current increase, you can use that either.

But you can't have voltage increase with no current increase, they are linked. Unless there is a proportionate change in resistance with increasing voltage, which there isn't in headphones.


Shredder-sama t1_j9g8yw8 wrote

P=V^2 /R -> V(x2)^2 /R(no change) you get a P(x4) change.


suppaboy228 t1_j9bi6kt wrote

6.3 is much smoother imo. XLR doesn't have a tactile snap and doesn't feel as secure as jacks (wobbly, especially when used for a long time)


pongpaktecha t1_j9e5aqf wrote

You must be using the wrong XLR plugs and receptacles then. High quality Neutrik XLRs are super durable and have a very satisfying click when latched and are not at all wobbly. I've definitely had some 1/4 inch jacks get finicky on me when you move the plug around


suppaboy228 t1_j9ecvxt wrote

Since the receptacle is friction fit, it will wear out and will be wobbly in a year of active use. It will hold itself with the latch and will not lose signal, but not very sturdy.

I have been using both neutrik and switchcraft connectors, 100% original. Thay may seem good for a long time at home, but when used in a studio environment, they wear out quite fast.


DeathsingerQc t1_j9bj6kg wrote

Bigger = better

But seriously it depends on the amp / cable, the one I use is secure in there, I need to pull kinda hard to take it out and the ones I use for my preamps have a locking thing on both ends.

If I accidentally pull my headphones with 6.3 the 6.3 will come out, with xlr the amp comes flying with the headphones. Which is probably not something you want but it is definitely not disconnecting by accident.


suppaboy228 t1_j9bjo55 wrote

Yes, it may be stuck hard, but the tactile feel of insertion and pulling out is very unpleasant. It is click-clack with 6.3 and all of the jacks with the ball end. Friction fit plugs - nah. And the fixator doesn't help either.

DasGutYa t1_j9c8ert wrote

You can get 3.5mm TRRS for certain headphones that are cabled for dual side single ended and a single sided balanced connection like the HE R9.

It's super jank and can cause a short if you use a normal dual 3.5mm balanced but it's the simplest solution to accommodate wireless add ons like the blue mini whilst maintaining compatibility with unbalanced dual input cables that most companies use.

But yea, the pic is a Chad 4.4mm.

Designer-Edge-5394 t1_j9bkkxk wrote

What about old school dual 3-pin XLRs? 😉


pieman3141 t1_j9coa78 wrote

Tyll, the guy who basically adopted that connector, said that he regretted using it for his early headroom devices.


Designer-Edge-5394 t1_j9e8uj6 wrote

Interesting, why?


pieman3141 t1_j9ee0s7 wrote

IIRC, he said they were clunky and he had difficulty wiring it all up. Also, most headphones don't need balanced outputs, and I think Tyll was kinda ambivalent about whether he preferred single-ended or balanced.


Designer-Edge-5394 t1_j9eibmq wrote

Ah OK. Well, they might be a bit heftier than the rest of the options but tbh not much worse than, say, 4-pin XLR when it comes to wiring up and handling. Once you connect them they stay there, right? ;-) I use HartAudio's cables and interconnects. Recently ordered the dual 3-pin XLR interconnect just out of curiosity and they seem to help open up the sound(stage), at least on my system. I haven't A/B'ed them but suddenly all my headphones sound more open and wide without losing detail. My HD660S now sounds better that they ever did before, and surprisingly open. I might be wrong and it all may be placebo effect, but what I can say with absolute confidence is that the volume knob on my Pro iCAN Sig. very rarely needs to go further than 9 o'clock these days. I did some research but couldn't find anything useful to understand what may be going on in terms of power delivery, etc. as compared to regular 4-pin XLR connections.


pieman3141 t1_j9cnm1g wrote

You forgot 2x 3-pin XLR that Tyll basically adopted during the early 2000s, and the RSA balanced jack that was somewhat "popular" (as far as the head-fi community went) back in the late 2000s. Might be a few more obscure ones that I'm forgetting - Sony's 2x 3.5mm connector, and the 2x 6.3mm connector.

Anyways, I'd also make the 3.5mm connector A-tier, 6.3mm B-tier, and 4-pin C-tier.

2.5 mm connectors have less impedance than 3.5mm and 4.4mm, they are objectively better.
