Summary
Among the 20 monitor headphones, SRH840A 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
- Ease of driving (40 Ω, 4 points): You can easily get enough volume even from an audio interface or a smartphone.
- Low-frequency range (5 Hz, 5 points): You can check the low end solidly.
- 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 (273 g, 2 points): 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 enough volume from an audio interface or smartphone without a headphone amplifier; people who want to check the low end solidly; people who want less sound leakage while recording.
Main features of SRH840A
Closed-back with a wide frequency range
They are closed-back headphones with 40 mm neodymium dynamic drivers, published with a frequency response of 5 to 25,000 Hz. The manufacturer explains that they are tuned for rich bass, bright mids and extended highs.
Folding, a detachable cable and a carrying bag
They fold flat. The cable is a locking detachable one (3 m, straight), and a carrying bag is included.
Specifications
The impedance is 40 Ω, the sensitivity is 97 dB/mW and the weight is 273 g without the cable.
Where it is useful
- Handling both vocal recording and mix checking with one pair
- Carrying them around
Rating by criterion
Ease of driving: 4 / 5
Whether you can get volume without a headphone amplifier (impedance). The smaller the number, the easier they are to drive.
SRH840A: 40 Ω. That is a high rating among the products we compared. You can easily get enough volume even from an audio interface or a smartphone.
Low-frequency range: 5 / 5
How low a sound they can reproduce (the lower limit of the frequency response).
SRH840A: 5 Hz. That is a high rating among the products we compared. You can check the low end solidly.
High-frequency range: 3 / 5
How high a sound they can reproduce (the upper limit of the frequency response).
SRH840A: 25,000 Hz. That is a standard rating among the products we compared.
Lightness: 2 / 5
The weight of the headphones. The lighter they are, the less they tire you over long periods.
SRH840A: 273 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.
SRH840A: 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 40 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. For reference, the sensitivity (loudness per 1 V) is 111 dB/V.
