Quick answer: The Audio-Technica ATH-M20x (around $49-59) is the headphone we’d buy for most digital piano players — closed-back for quiet, late-night practice, with a 47-ohm impedance that gets properly loud straight out of a piano’s weak onboard headphone jack. If isolation doesn’t matter and you want the lightest possible fit for long sessions, Roland’s own RH-A7 (around $150-180) is built specifically for its digital pianos. The spec that actually matters here is impedance, not price: Kawai’s own published guidance recommends headphones between 16 and 100 ohms for its digital pianos, and some pricier “studio” headphones are built in 250-ohm-plus versions that sound noticeably quieter plugged straight into a piano instead of a dedicated amp.
Every digital piano buying guide on this site eventually says the same thing — “plan on headphones for serious practice.” None of them tell you which headphones actually work well plugged into a piano’s jack versus a pair built for something else entirely. That’s the gap this guide fills.

1. Audio-Technica ATH-M20x — Best All-Around / Isolation
Audio-Technica ATH-M20x
- Closed-back design seals around the ear, so late-night practice doesn't carry through a thin apartment wall.
- 47-ohm impedance is squarely inside the 16-100-ohm range Kawai recommends for its own digital pianos — full volume without hunting for the knob.
- Ships with the 3.5mm-to-1/4-inch adapter you'll need for most digital piano headphone jacks.

For most players, the M20x is the headphone to just buy and stop thinking about: it’s inexpensive, the closed-back cups block enough outside noise that you’re not fighting a TV in the next room, and the 47-ohm impedance means a piano’s modest onboard headphone amp can drive it to full, clean volume without strain. It’s not a specialist pick for critical listening, but for the actual job — hearing your own playing clearly while staying quiet for everyone else in the house — it’s the one most people should start with.
2. Roland RH-A7 — Piano-Specific Comfort
Roland RH-A7
- Open-air design built by Roland specifically for its own digital pianos, with a lighter clamp for multi-hour sessions.
- 34-ohm impedance — comfortably inside the low-impedance range a piano's headphone jack can drive properly.
- Open-back means sound leaks out and ambient noise leaks in — not the pick for quiet practice next to a sleeping household.
Roland designed the RH-A7 around the exact use case in this guide, which is why it shows up on the recommended-accessory list for boards like our FP-10 and FP-30X. The open-air build is genuinely more comfortable for the two-hour practice sessions a serious student puts in, since there’s no clamping pressure or ear-cup heat buildup. The trade-off is isolation: open-back headphones are built to breathe, which means they don’t block outside sound and they let your own playing leak out at a lower but audible level — fine in a dedicated music room, a worse fit for a shared apartment at 11pm.
3. Audio-Technica ATH-M50x — Step-Up Sound Quality
Audio-Technica ATH-M50x
- Closed-back studio monitor headphone with noticeably more detail and bass extension than the M20x.
- 38-ohm impedance — despite the "studio" branding, it's still built to run fine straight out of a piano's jack, unlike some higher-impedance studio headphones.
- Heavier clamp than the RH-A7; best for sessions under an hour or two.
The M50x is the pick for players who’ve outgrown the M20x’s sound and want to actually hear the difference between the sample sets on a piano like our best digital piano picks. It’s closed-back, so you keep the isolation, and at 38 ohms it stays easy for a piano’s built-in headphone amp to drive — this is the detail that matters more than the “studio” label. Plenty of headphones wearing that same label ship in a 250-ohm-plus version built for a separate headphone amp or audio interface, not a piano jack, and those versions will sound disappointingly quiet here.
The impedance trap: why “better” headphones can sound quieter
This is the spec almost nobody checks before buying. A digital piano’s headphone output is a small, low-power amplifier built into the instrument — not a dedicated headphone amp like you’d find in a recording studio. Kawai publishes this directly in its own support documentation: the company recommends headphones between 16 and 100 ohms for its pianos, and warns that higher-impedance headphones will produce lower volume at the same volume setting.
The trap is that impedance has nothing to do with price or “professional” branding. Beyerdynamic’s popular DT 770 Pro, a studio headphone many players recognize by name, ships in three separate versions — 32, 80, and 250 ohms — and the 250-ohm version is explicitly built for a strong headphone output or a dedicated amp, not a consumer device. Grab that version for a digital piano and you’ll likely find yourself turning the piano’s volume all the way up and still not getting the headphones genuinely loud. All three picks above sit in the 34-to-47-ohm range for exactly this reason — none of them need more power than a piano’s jack can supply.
One more wiring detail worth knowing before you order: nearly every digital piano uses a full-size 1/4-inch (6.3mm) stereo jack, not the 3.5mm mini-jack on your phone or laptop. Every headphone above ships with the adapter already included, so it’s a non-issue with these picks — but it’s worth checking before buying a pair that doesn’t mention one.
If your piano happens to have two headphone jacks, like the Yamaha P-225 in our best digital piano roundup, you can skip the impedance math on a Y-splitter entirely — just plug two pairs in directly and use the piano’s Duo mode to split the keyboard for a teacher and student session.
The bottom line
For most players, the Audio-Technica ATH-M20x is the easy, inexpensive answer — closed-back isolation and an impedance low enough to get genuinely loud out of any digital piano. Want the lightest possible fit for long sessions in a room where isolation doesn’t matter? The Roland RH-A7 is purpose-built for it. Ready to spend more for noticeably better sound without risking the impedance trap? The ATH-M50x delivers that upgrade safely. Whichever you choose, check the ohm rating on the box before you check the reviews — it predicts how loud your new headphones will actually get more reliably than the price does.
