How can you tell how many ohms you motherboard can supply?

[OnionRings]

As far as I'm aware, its not a normal spec people look at so it isn't listed on the website. Curious as I wanted to try a pair of DT990 pro 250 ohms, but I don't have an AMP. Apparently they also make an 80 ohm version, but I don't know if this board does that either. Its a tomahawk b450 max.

 

Edit: https://www.amazon.com/beyerdynamic-Headphones-4-Channel-Headphone-Amplifier/dp/B07M7283Y6?ref_=ast_sto_dp&th=1 so they have a bundle with an AMP, doesn't cost too much, but I have 0 idea how an AMP works. I imagine it plugs into a power supply in the wall, but how does it connect to your PC? Yes I'm really asking this very real question I'm special, always just used sub 100 dollar headsets lmao. Only amp I ever used was the astro A40s and thats not even a real amp that thing was like just a volume mixer knob lol.

it really simple without amp you wont getting max volume maybe not even sound. Without proper amp you wont be getting quality of that headphones.

Well firstly, the motherboard dosn't supply Ohms. Ohms are a measure of electrical resistance. That said I have no idea if you can just plug these into your front audio port or not, and no idea how the question should be worded.

Luckily I know a little bit more about amps (I've helped my brother with quite alot of it, but am not an expert) and I believe what you'd need to do is connect 2 of these ports (the ones labled left and right) to the Amp, using a Aux RCA to 6.35mm Stereo Jack cable.

Well the reviews on the included amp aren't great, so I either can try to look up a good cheap amp or just stick with basic headphones that dont need one.

Do you know of an AMP that doesnt break the bank that would be solid? I know very little, the included amp in the link I sent looks like poor reviews, buzzing noise, etc.

Unfortuantly, while I know how to set them up, I have no idea how to shop for them. The common advice I often hear for audio equipment is buy used profession grade equipment, cause the prices are way lower and the quality way higher than new consumer grade equipment. But I honestly couldn't tell a good deal from a bad deal.

[thrasher_565]

an amp added power from like the wall or battery and in turn the head phones can use more power for more louder sound.

 

it takes and input for an device and out the the headphones.

there different ones that use different connectors.

 

i beleave you can also buy an pcie amp as well.

No problem friend.

I think sound cards work too right?

Just try it, nothing will break. Higher impedance (ohms) headphones draw less current at the same voltage. Which means they need a higher voltage to reach the same loudness. So in short when its not loud enough you need an amp or external interface that is loud enough for you.

[saintlouisbagels]

Along the same lines as @Heats with Nvidia, just try it dude.

 

The Beyerdynamic trio of headphones don't really need an amplifier. They're all sensitive enough to run off most normal sources, including a modern desktop motherboard. There are other variables that affect audio quality beyond just loudness, but it's questionable if they're audible. (output impedance, damping factor, etc.)

 

I would recommend this if you think you must have an amplifier

https://www.amazon.com/Fanmusic-TANCHJIM-Space-Headphone-Amplifier/dp/B0BN3C635G/

 

If we're talking about headphone amplifiers with no built-in DAC, you simply feed it an audio signal from the motherboard's "Line Out" or "Front Speaker" output.

 

If we're talking about a DAC/amp, then there's usually a USB input. If you're unfortunate enough to have a DAC/amp without USB, you could feed optical/TOSLINK from the computer to the DAC/amp.

 

I've used both 80ohm and 250ohm DT770's with various sources, and I don't feel that I gain anything from using them with a proper amplifier.

[Pawer8]

It's not just about the ohms. It's also about the sensitivity.

That said the Mobo won't drive the 250ohm one to its full potential

 

You should look at reviews as the sound of the 80ohm and 250ohm is different

Ok, might give it a try, they sell on amazon so I could always return if poopy.

I could try looking up the harmon target or whatever its called, see the difference.

I think it was DMS that had a review comparing the different ohm headphones. Look at that

[OnionRings]

I think I might just look into getting an amp, if I get them I want them to be as best as they can you know? And with how cheap the 990s are, I should be able to get an AMP too, and still be under the cost of like A50s for example.

Amplifiers and DACs are like 1% audio improvement. If you want better audio you buy better headphones.

With that said, if your motherboard happens to have a shitty DAC and amplifier, then yeah buying a DAC/amp is worth it regardless if you're buying new headphones or not. Just don't be surprised if a DAC/amp makes you wonder "I think this sounds better...??" because then that means your motherboard was already adequate, or the improvement is so small that you really can't tell.

In this review, the writer was confused why the Fosi amp sounded worse than his typical amp. It turned out that the Fosi amp was awfully designed and made the low and high frequencies were quieter than the mids. So don't just buy any amp - buy one that's actually measured to not color the audio.
