AKG 2144Z07020 - Inner headband K121, 141

AKG 2144Z07020 - Inner Headband (Suspension Band) for K121 and K141

The AKG 2144Z07020 is the original inner headband (Bügelband) that is part of the signature self-adjusting system of AKG headphones. This replacement fits under the outer arch and restores comfort and a consistent fit on the head after wear and tear. It is documented as position 2 "Headband" in the official K121 Studio parts list and is secured using the headband's guides and elastic elements.

It's sold as an OEM replacement and is the reference number indicated for the K121 . Many retailers also list it for the K141 family (earlier/Studio versions); however, for the K141 MKII, AKG specifies a different inner headband reference . Therefore, if your model is the K141, we recommend checking the exact version before purchasing.
