AKG 2058Z35010 - Inner headband K271,K240, HSC/HSD 271

AKG 2058Z35010 - Inner headband strap for K240 MKII, K271 MKII and HSC/HSD 271

The AKG 2058Z35010 is the original inner headband for several AKG professional headphones and headsets. This band—referred to in the documentation as the Headband / Bügelband —is part of the self-adjusting system that rests on the head and works in conjunction with the rubber loops and side guides to provide a stable and comfortable fit during long sessions. It is the manufacturer-recommended replacement for the K240 MKII , K271 MKII , and HSC271/HSD271 headsets , ensuring compatibility and a fit with factory tolerances.

In addition to restoring ergonomics, this part is involved in the correct functioning of the assembly: in the HSC/HSD 271 the helmet harness activates the auto mute system when putting on or taking off the headset, and in the K271 MKII the headband assembly integrates the mechanism and the associated microswitches, as reflected in the official parts list.

Main features

• AKG OEM Replacement : Official inner headband for a precise fit and professional durability.
• Verified compatibility : K240 MKII, K271 MKII and HSC271/HSD271 headsets.

Use cases

• Replacement in HSC/HSD 271 when the auto-tuning loses travel or the automatic mute stops working correctly due to mechanical wear.
