6.5mm vs 3.5mm jacks?

[killerdann12]

So i've been looking at o2 amp/dac and was wondering if there is a difference in quality between the 2. the 6.5mm ones all cost more.

Nope nope nope.

Quality as in Headphone listening? then No. there is no quality differences.

any quality difference? not just audio, idk

[Toddwjp]

no quality difference, just 6.25 are preferred because it just locks better and is physically more reliable

Well there is no differences. So get whatever your headphone plug is.

You will need adapter if you go for 6.5 and you have 3.5 headphones.

There are no advantages.

6.5mm are used on stages so that connector doesnt pop out easily.

OK, thanks I was just wondering as I see 6.5mm jack and my new headphones came with an 6.5mm adapter

The bigger jack is more expensive because it involves more labor to install it into the O2, not because it makes any difference to the sound quality.

Sound quality? No change... Aesthetics and Support (without an adapter) for certain sound hardware and reliability are the only differences it's like USB vs Micro USB assuming they're the same gen of USB (EG as long as they are both gen 2 or 3)

1/4" jacks are more durable but in reality it's fairly negligible.

I personally went with the larger jack on my 02 simply because most headphones on the market that are middle to high end come with a 1/4" adapter plug preinstalled, so there is no worry about losing it.

I have a box full of those adapters...I have more adapters than headphones that can use those adapters lol.

The jack itself is also more durable from plugging in and out. 3,5mm jacks are more prone to loosen the grip than the 6,3mm.
