Rank #10 in Best Studio Headphones 2026: 10 Ranked, 32 Ohm to 250 Ohm
M-Audio HDH40 Closed-Back Over-Ear Headphones
Price and rating as shown on Amazon when we collected them. Both change.
The M-Audio HDH40 is a closed-back over-ear headphone at £33.99, and it takes the last place in this guide. It carries 4.5 stars from 1,413 ratings and sits 37th in Amazon's Studio Headphones category ranking. The figures that decide whether it works with your kit are on the listing: 32 ohm impedance and 95dB sensitivity, with a 40mm neodymium dynamic driver and a 2.7m cable. That 32 ohm figure puts it at the bottom of the impedance range in this guide, level with the OneOdio Pro-002, MAONO MH700 and Vic Firth SIH3, against 250 ohm for the beyerdynamic DT 990 PRO.
The finding on this fiche is a listing that disagrees with itself. The box contents field lists a cable, ear cushions and a headband as three separate items, while the fourth bullet point describes a 2.7m fixed cable — a fixed cable is attached to the headphones, so it should not also appear as a supplied item. The same listing gives a Control Method of 'Touch' and a Control Type of 'Media Control', yet none of the five bullet points describes any control at all; the only connection described is the fixed cable and the 1/4" adapter for mixers and audio interfaces. Everything on this page is taken from the Amazon product listing, not from our own testing.
How those 1,413 ratings break down

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Why did you choose this product over others?:Great quality for the price. Nice bass too. Super comfy and keeps outside sounds out really well even though it doesn't have a noise cancelling button, as they fit nicely over the ears, which has been great when flying in planes. Really long cable too which has been useful for recording music. Thoroughly recommend”
Verified purchase“Better than expected for the price. Me and my boyfriend have got a home studio set up so he bought me these so we can record and playback and they are very comfy and the sound quality is brilliant! We will be ordering another pair 👌🏽”

Questions people ask
Do the M-Audio HDH40 headphones need an amplifier?
The listing gives an impedance of 32 ohm and a sensitivity of 95dB and says this 'ensures compatibility with the widest range of equipment'. It never states that an external amp is required.
What comes in the box with the M-Audio HDH40?
The Box Contents field lists a cable, ear cushions and a headband, but the bullet points describe a 2.7m fixed cable — the two parts of the listing do not agree on whether the cable is attached or supplied separately.
Can I use the M-Audio HDH40 with a phone or a games console?
Yes, per the listing. It says to connect tablets and smartphones directly, or to use the 1/4" adapter for mixers, audio interfaces and digital pianos, and lists iPhone, Android and PlayStation as compatible.
How long is the cable on the M-Audio HDH40?
2.7m, and the listing describes it as fixed rather than detachable.
Is the M-Audio HDH40 touch controlled?
The listing carries a Control Method of 'Touch' and a Control Type of 'Media Control', but no bullet point describes a touch control or a button. The only connection described is the fixed cable plus 1/4" adapter.
What is the impedance of the M-Audio HDH40?
32 ohm, the lowest figure quoted in this guide, matched by the OneOdio Pro-002, MAONO MH700 and Vic Firth SIH3.
