Main trade-off
beyerdynamic DT 700 PRO X
At 350 g without cable, it is heavier than many folding studio pairs.
Head-to-head
beyerdynamic DT 700 PRO X vs DT 900 PRO X: DT 700 suits shared rooms, DT 900 leaks sound
The short answer
Choose DT 700 PRO X for recording with a live microphone or listening near other people. Choose DT 900 PRO X for a quiet private room where open-back leakage is acceptable. Their cable kits and nominal impedance match, and only 5 g separates their stated weights.
Before you choose
The reasoning and the trade-offs
The weight difference is only 1.4%
Do not choose the open model purely to save weight. The room requirement is much larger than the 5 g gap.
What this is based on
(350 - 345) / 350 × 100 = 1.43%.

Winner by situation
Start with what you need it to do
Recording a vocal beside the mic
Open cups can feed headphone playback back into the microphone.

Quiet room with nobody nearby
That environment allows the DT 900 open design to be used as intended.

What matters in practice
The differences that matter
The weight difference is only 1.4%
Do not choose the open model purely to save weight. The room requirement is much larger than the 5 g gap.
How we reached this conclusion
(350 - 345) / 350 × 100 = 1.43%.
Cable reach is an exact tie
Each package supplies the same 1.8 m and 3 m options.
How we reached this conclusion
Both manufacturer package lists state two detachable straight cables at those lengths.
The shared room eliminates one option early
If open sound leakage is unacceptable, DT 900 fails that requirement regardless of its other specifications.
How we reached this conclusion
DT 900 is open-back and DT 700 is closed-back. This is a construction-based fit conclusion, not a measured leakage threshold.
Check your own setup
Which headphones work with the way you listen?
Start with the way you listen. USB charging is not the same as USB audio, and some headphones need power even with a cable. These choices are examples until you apply yours.

Does not meet these checksThis model does not play over Bluetooth.
beyerdynamic DT 900 PRO X
Does not meet these checksThis model does not play over Bluetooth.
Battery figures are manufacturer claims for the stated mode, not measured travel time. Volume, codec, calls and battery age change runtime. Closed earcups can still leak sound. Weight alone does not predict comfort. USB audio needs a compatible source and cable. This check does not assess sound quality, microphone quality or amplifier power.
Choice A
beyerdynamic, DT 700 PRO X
DT 700 PRO X
A closed studio pair with two locking mini-XLR cables. It gives you a shorter desk lead and a longer studio lead in the same box.
- Best matched use
- Closed-back recording with replaceable cable connections
Checked facts
- The 48-ohm STELLAR.45 driver is used in a closed-back enclosure.
- The weight without cable is 350 g.
- Detachable 1.8 m and 3 m mini-XLR cables are included.
Choice B
beyerdynamic, DT 900 PRO X
DT 900 PRO X
An open-back studio model with two detachable cable lengths. Best kept at a quiet mixing desk, away from microphones that might pick up the playback.
- Best matched use
- A quiet studio desk with replaceable long and short cables
Checked facts
- The manufacturer specifies an open-back 48-ohm design.
- It weighs 345 g without cable.
- The package includes 1.8 m and 3 m locking mini-XLR cables.
Meaningful differences
What changes the fit
| What changes | beyerdynamic DT 700 PRO X | beyerdynamic DT 900 PRO X | Why it matters |
|---|---|---|---|
| Ear-cup construction | Closed-back | Open-back | Room noise and leakage matter more than the model number. |
| Weight without cable | 350 g | 345 g | Only 5 g separates the published figures. |
| Nominal impedance | 48 ohms | 48 ohms | The electrical rating does not create an upgrade tier. |
| Short supplied lead | 1.8 m | 1.8 m | Both suit a close interface. |
| Long supplied lead | 3 m | 3 m | Both cover the same distant headphone output. |
| Cable connector | Locking mini-XLR | Locking mini-XLR | Both have a replaceable cable. |
| ANC | No | No | Closed cups are not active noise cancellation. |
What you give up
Every choice has a cost
If you choose beyerdynamic DT 700 PRO X
- It does not fold inward and has no wireless mode.
If you choose beyerdynamic DT 900 PRO X
- It is not a folding travel headphone.
Recommendation switch
The decision flips if...
You record beside a live microphone.
Choose beyerdynamic DT 700 PRO X. A live microphone can hear playback that escapes open cups. Closed DT 700 is the more practical choice for tracking, while monitor volume and mic placement still need attention.
You want an open-back headphone for a quiet room.
Choose beyerdynamic DT 900 PRO X. DT 900 makes sense when background noise is low and nobody objects to hearing your music. An open headphone cannot be made private by picking a different cable or amplifier.
What matters in practice
How to make the call
Recording changes the answer
A live microphone can hear playback that escapes open cups. Closed DT 700 is the more practical choice for tracking, while monitor volume and mic placement still need attention.
Give the open model a suitable room
DT 900 makes sense when background noise is low and nobody objects to hearing your music. An open headphone cannot be made private by picking a different cable or amplifier.
The rest of the kit does not force a choice
Both have matching cable lengths and nominal impedance. Choose the room fit first, then try the clamp and cushions. The 5 g published weight difference is not a strong standalone buying reason.
What this comparison cannot tell you
- Closed construction does not guarantee zero microphone bleed.
- No exact noise-isolation difference is calculated.
