Might be another dumb question but where can I find a 2.5mm to 1/4" adapter?

You said it not me try monoprice silly!

I looked and I'm not seeing that they have any. I'm kinda bummed that they are coming in a couple days and I can't use them without the adapter!

Are you sure it isn't a typo? I'm sure a 3.5 to 1/4" adapter would work.

Very good deal for two adapters, and they look and feel as good as they are in the pictures

I have a 3.5mm to 1/4" adapters, but everyone is saying these are 2.5mm? That would mean I need to get a 2.5mm to 1/4"?

I have a bunch of 3.5mm to 1/4" adapters but everyone is saying this is 2.5mm. That would mean I need a 2.5mm to 1/4", correct?

​I'm pretty sure the phones have an 1/8th inch (3.5mm) connector.
In which case you're good. Why would full size cans have anyting less that 3.5mm?

 

[Spiral Out]

It looks like a 3.5mm from the picture in this thread. 

 

[vccasanova]

Anyone have any actual confirmation if it's 2.5mm or 3.5mm? I've read 2 people say that it's a 2.5mm so far and no one has said 3.5mm. 

 

[GamingNut]

So I don't know for sure but it would be absurd for full size headphones to have a 2.5mm connector. Sorry I can't give you full confirmation

​The unboxing video some pages back shows a close up of the connector. That is a 3.5mm connector

I sure hope everyone saying that it didn't come with a 2.5mm to 1/4" adapter made a typo because even in that YouTube video, it's really hard to tell because the [modified by moderator] reviewer won't stop spinning the connector to get a clear shot at it.

These are of poor quality. Monoprice's plastic ones are better.

Ok really bad at electric calculations... but is this right?

I read that the CCA is 2 Vrms, and these headphones are 50 ohm.

So V/r=I... or 2 Volt/50ohm=0.04 Amp
P=IV... 2 Volt*0.04 Amp=0.08 Watt or 80 mW. Which is less than the minimum 200 mW requirement, and significantly less than the 4 Watt maximum.

I think you forgot to add Chromecast's 34.5 ohm output impedance to the formula here.
So, 2/(50+34.5) = 0.0237A
2*0.0237 = 0.047W ~ 50mW
