In essence how much power a headphone allows in. Low ohms mean more power goes through from the source and a high ohm rating means less power goes through.
For everyday use this means a phone can drive those low ohm cans to a nice high volume and decent sound where as a higher ohm pair will result in lower volume thus you'll see the subject of amps come up to increase the power to the headphone.
Which is why a higher ohm can is typically intended for higher powered, higher quality audio equipment.

I liked the.p's explanation. Want to add this. Think of a headphone's use of the work 'Ohms' as an 'adjective' for 'resistance'. If you've ever check a car amp's specs it might say 100W at 8Ohms and 180W at 4Ohms right? Well most consumer headphones over/on/IEMs use low Ohms so smart phones, devices, run of the mill Receives etc. can easily power them. They will often display their db's at 1W at 20Ohms as example - describing their efficiency of how loud they can produce sound at your Ear entrance as a given power level - often in fractions of a Watt. To cut this short - audiophiles often prefer higher Ohm Cans (because they use dedicated DACs and Headphones Amp separate or combined that have plenty of power. The quick and dirty of the advantage is this. a) Fuller sounds impact, imaging - etc. at the same volume. b) perhaps most important - Noise Floor - Dead Silence between notes/chords/licks/vocals - much less hiss, popping and harmonic distortion most often because the higher Ohm Headphones won't emphasize the small imperfections in the source content as prominently because they are less efficient and won't put the little accidental stuff in your head as easily. **Also when getting more particular with higher res content or even from basic CD-quality sources - you can have cleaner divides between BASS-MiDS-TREBLE with higher Ohm cans. So def try a pair but know you're gonna need to use even a $30 FiiO Amp or better to use them with your phone of low power output electronics. My favorite portable DAC/AMP is my iFi Micro iDSD BL and my favorite desktop headphone Amp is my iFi Pro iCan; with a separate DAC. I have also owned an Audeze Deckard Combo for 2 years and its spot on for power and sound for the money spent. Hope this helps Smilie

So basically buying these are useless when playing from a phone like a lg v30 which i heard has a good audio. You still need to get an amp just to use a 600ohms.

Actually, the LG V20/30 are equipped to drive high ohm head phones. I have these cans and they sound great on my V20! Phone detects (and informs you) when a high Ohm set of head phones is connected, then ups the juice accordingly. I'm not sure what other manufactures have quality DACs built in.

Yes...I highly doubt you would be happy with these, even at this reasonable of a price, if you're only using your phone.

Much more in depth than I probably had the patience to do 😉 😀
Thanks for putting in the time to do it!

Why does the DT770s never go on sale? Don't need open earphones. Need a deal on some good closed ones!
