Detail 01
Semi-open design
Sound passes both ways. Roomier, less closed-in sound, but a click track bleeds straight into a nearby mic.

AKGK240 MKII Studio Headphones
Independent shopping perspective
The Korena take
Semi-open circumaural studio headphones at $199. Built for mixing, editing and practice in a room where a little sound leaking out doesn't matter.
Strong match
Who this is for
- Mixing and editing at a desk, where isolation isn't the point
- Long sessions — 240g with pads around the ear
- Keys, synth or guitar practice through an interface headphone jack
Consider the trade-offs
When to look elsewhere
- Tracking vocals with a live mic in the room
- Commuting, planes, or any loud space — nothing gets blocked
- Anyone who needs a sealed, isolating pair for loud stages
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
55 ohms impedance
Easy to drive. An interface, mixer or laptop output runs these without a dedicated headphone amp.
Detail 03
91 dB/mW sensitivity
Moderately efficient. You'll turn the volume knob higher than with consumer headphones to reach the same level.
Detail 04
Circumaural fit
Pads sit around the ear rather than on it, so pressure lands on the head, not the cartilage.
Detail 05
Plug-in (detachable) cable
The cable is what usually dies first. Here it unplugs and swaps instead of retiring the headphones.
Detail 06
Screw-on 1/4" adapter
Native connector is a mini jack. The adapter threads on, so it won't drop off behind a console.
Final check
Know before you order
- 01Semi-open leaks — plan a closed pair for vocal tracking with an open mic
- 02Cable unplugs, so keep a spare if the pair travels
- 03Keep the screw-on 1/4" adapter with the cable for studio gear
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I use these to record vocals?
They leak. Semi-open cups let the headphone mix escape into an open mic, and it lands in the take. Fine for quiet monitoring at low levels, not ideal for close-mic'd vocals.
02Do I need a headphone amp?
No. At 55 ohms they run from an audio interface, mixer or laptop output. A dedicated amp adds headroom but isn't required to reach usable volume.
03Do these block outside noise?
No. The semi-open design is deliberately not sealed, so room noise comes in and your audio goes out. Use them somewhere quiet.
04Can I replace the cable?
Yes. It's a plug-in cable, not hardwired, so a damaged one is swapped rather than soldered. The gold-plated mini jack end takes the screw-on 1/4" adapter.
