AKG K240 Studio Professional Headphones - Semi-Open

Gearank High Notes

Gearank Recommended

The K240 Studio first appeared on our recommended list for Studio Headphones Under $100 in May 2017 and it remains on that list today.


According to AKG, the K240 Studio is their most popular model.

While the original K240 was created in 1975, it has gone through many minor revisions before branching out into the K240 MKII and the K240 Studio.

Both models are very similar. The MKII has a different aesthetic and has additional accessories but the Lower-priced "Studio Model" without the fancy accoutrements edges out it's more expensive sibling.

The K240 design has been around for decades. The latest incarnation in the very affordable K240 studio brings together time-tested engineering with modern materials.

If you can live without the fancy bells and whistles of it's more expensive (but nearly identical) brother the MKII, the Studio version rewards you with incredible midrange clarity and fast transient response.
