Detail 01
250 ohm
Needs more voltage to reach volume. Sounds thin and quiet on weak outputs, tighter and more controlled on a proper amp.

beyerdynamicDT 770 PRO Studio Closed-Back Headphones - 250 ohms
1/14
Independent shopping perspective
The Korena take
Closed-back studio headphones at 250 ohms with a coiled cable — the version for desks with a real headphone amp or a strong interface output.
Strong match
Who this is for
- Studio desks with a dedicated headphone amp
- Tracking in a booth where the coiled cable stays out of the way
- Long mixing and editing sessions at a fixed position
Consider the trade-offs
When to look elsewhere
- Phones and laptops — they will not get loud enough
- Anyone needing a portable, foldable, detachable-cable headphone
- Flat-response mix referencing; the tuning is scooped and bright
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
3 m coiled cable
Stretches when you lean in, retracts when you sit back. Heavier than a straight cable and it tugs a bit.
Detail 03
Closed-back
Keeps sound off the microphone. Usable while tracking, unlike open-back headphones.
Detail 04
18 dBA isolation
Cuts room and click bleed noticeably, but it's passive — this is not noise cancelling.
Detail 05
Replaceable velour pads
Pads are the first part to wear. Swapping them restores comfort and seal instead of replacing the headphones.
Detail 06
380 g with cable
Heavier than the 80 ohm version because of the coiled cable. Spring steel headband and light 3.5 N clamp keep it wearable.
Final check
Know before you order
- 01Cable is fixed and single-sided — not user-swappable.
- 023.5 mm plug with a screw-on 1/4 inch adapter included.
- 03Check your headphone output can actually drive 250 ohms before buying.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Do I need an amp for the 250 ohm version?
Effectively yes. A dedicated headphone amp or a strong interface output. Phone and laptop jacks will run out of volume and sound thin.
02What's the difference from the 80 ohm model?
Impedance and cable. 250 ohm ships with a 3 m coiled cable and needs more drive; 80 ohm has a 3 m straight cable and runs off almost anything.
03Is the higher impedance version better sounding?
It's not automatically better. Given enough power it tends to sound tighter and more controlled; underpowered it sounds worse than the 80 ohm.
04Are the ear pads replaceable?
Yes. The velour pads are a replaceable part, as is much of the rest of the construction.
