Hardware & signal path
Impedance
Impedance, in ohms, is how much a pair of headphones resists the signal driving them. Higher impedance needs more voltage for the same loudness, which is why one pair can be loud on one output and thin on another.
In practice
Buy DJ headphones between 32 and 64 ohms. High-impedance studio pairs are quieter on exactly the outputs you need them loud on.
If you already own a 250-ohm studio pair, keep them for the studio and buy something low-impedance and closed-back for gigs — sensitivity matters as much as the ohm figure, and a pair rated around 100 dB per milliwatt at 32 ohms will be comfortably loud anywhere. Test on the quietest output you expect to meet rather than the loudest: the question is whether they are usable on a tired booth mixer, not whether they can hurt you on a fresh one.

Why it matters
It is the specification that decides whether the headphones you bought for home will work in a booth you have never seen. DJ headphones sit deliberately low — usually between 32 and 64 ohms — so that a phone, a controller and a club mixer all drive them adequately. Studio pairs at 250 or 600 ohms are a different tool and will disappoint you at a gig.
Low impedance is not automatically better. It draws more current, which on a weak output can distort before it gets loud, and it makes any hiss in the amplifier more audible. The reason DJ pairs land where they do is that it is the compromise that survives being plugged into anything.
Frequently asked
Are high-impedance headphones better quality?+
No — impedance describes electrical load, not sound. High-impedance pairs are common in studios because studio amplifiers are built for them, which is exactly why they underperform on a booth output.
What impedance should DJ headphones be?+
Between about 32 and 64 ohms. That range is loud enough on a phone, a controller and a club mixer without demanding more current than any of them can supply.
Does impedance matter for speakers too?+
It matters more, because a speaker load below what an amplifier is rated for can damage it. In a booth that is the venue’s problem, but it is the same specification doing the same job.

Headphone output
The headphone output is the mixer’s own amplifier feeding your headphones, with its own level control. What arrives there is set by the cue buttons and the cue mix knob, not by the channel faders or the master.
Amplifier
An amplifier takes the line-level signal leaving the mixer and raises it to the power a speaker needs. In a club it lives in a rack you will never see, usually behind a processor that handles crossover, delay and limiting.
Club sound system
A club sound system is the whole chain after the mixer: processor, amplifiers, subwoofers, main speakers and often delay or fill speakers, tuned together for one room by an engineer who is not in the booth.
Split cue
Split cue makes the headphones mono and sends the cued channel to one ear and the master to the other. You lose the stereo image and gain clean separation between the track you are cueing and the one playing.
