Summary
Among the 20 monitor headphones, DT 770 PRO X is rank A. The ranks run S, A, B and C, and A is second from the top. Averaging the scores for each criterion (out of 5) gives 3.8.
Strengths
- Low-frequency range (5 Hz, 5 points): You can check the low end solidly.
- High-frequency range (40,000 Hz, 5 points): You can check the fine details of the highs.
- Suitability for recording (sound leakage) (closed-back design, 5 points): They leak little sound, so they can be used while recording vocals.
Things to keep in mind
- Lightness (305 g, 1 point): They are on the heavy side, so you may tire in long sessions.
Who it suits: judging from the specifications, it suits people who want to check the low end solidly; people who want to check the fine details of the highs; people who want less sound leakage while recording.
Main features of DT 770 PRO X
Closed-back with STELLAR.45 drivers
They are over-ear closed-back headphones using STELLAR.45 drivers (5 to 40,000 Hz). The impedance is 48 Ω, and the manufacturer explains that they can be driven to studio quality even from low-output equipment.
Detachable cable and velour ear pads
The detachable cable locks in with a mini XLR (3.5 mm plug, with a 6.3 mm adapter). With velour ear pads and a replaceable headband, many of the parts are said to be replaceable.
Weight
The weight is 305 g without the cable.
Where it is useful
- Keeping the sound of the headphones out of the microphone while recording vocals
- Long mixing or monitoring sessions
Rating by criterion
Ease of driving: 3 / 5
Whether you can get volume without a headphone amplifier (impedance). The smaller the number, the easier they are to drive.
DT 770 PRO X: 48 Ω. That is a standard rating among the products we compared.
Low-frequency range: 5 / 5
How low a sound they can reproduce (the lower limit of the frequency response).
DT 770 PRO X: 5 Hz. That is a high rating among the products we compared. You can check the low end solidly.
High-frequency range: 5 / 5
How high a sound they can reproduce (the upper limit of the frequency response).
DT 770 PRO X: 40,000 Hz. That is a high rating among the products we compared. You can check the fine details of the highs.
Lightness: 1 / 5
The weight of the headphones. The lighter they are, the less they tire you over long periods.
DT 770 PRO X: 305 g. That is a modest rating among the products we compared. They are on the heavy side, so you may tire in long sessions.
Suitability for recording (sound leakage): 5 / 5
Whether they are closed-back, which leaks little sound. Less leakage means the headphone sound does not get into the microphone while you sing.
DT 770 PRO X: closed-back design. That is a high rating among the products we compared. They leak little sound, so they can be used while recording vocals.

How we score (Monitor headphones)
| Criterion | Basis | 5 pt | 4 pt | 3 pt | 2 pt | 1 pt |
|---|---|---|---|---|---|---|
| Ease of driving | Impedance (the lower it is, the easier to reach a good volume from a small amplifier) | ≤32 | ≤40 | ≤55 | ≤100 | >100 |
| Low-frequency range | Lower limit of the frequency response | ≤5 | ≤8 | ≤15 | ≤20 | >20 |
| High-frequency range | Upper limit of the frequency response | ≥40000 | ≥30000 | ≥25000 | ≥22000 | <22000 |
| Lightness | Weight (cable excluded) | ≤200 | ≤220 | ≤250 | ≤290 | >290 |
| Suitability for recording (sound leakage) | Closed-back or open-back (closed-back keeps sound out of the microphone while you sing) | Closed-back | — | — | — | Open-back |
Scored only on the body specifications published by the manufacturer. Price and accessories are not part of the score. Ease of driving is compared by impedance (Ω), which every manufacturer publishes. The lower the number, the easier it is to reach a good volume from the headphone jack of an audio interface or a smartphone, so a headphone amplifier is less likely to be needed (sensitivity is shown in the table for reference). "Suitability for recording" scores closed-back headphones higher because the sound is less likely to leak into the microphone while you sing. If you choose open-back headphones for mixing, you can ignore this item.

Before you buy
- They are closed-back. They leak little sound, so they are also easy to use for recording vocals.
- The impedance is 48 Ω. The impedance is on the low side, so it is relatively easy to reach a good volume even from the headphone jack of an audio interface.
