)asterisk Sennheiser asterisk has found itself in hot water with the Federal Cartel Office for manipulating the free market of premium headphones since at least 2015. According to Andreas Mundt, President of the Federal Cartel Office, the sound giant intentionally intervened prices when products were significantly below the recommended retail price (RRP). Traders usually complied with the requested price adjustments.
Mundt stressed that Sennheiser's employees received cartel law training, but they utilised this knowledge not to adhere to cartel law principles, but rather to camouflage price-fixing schemes.

Questionable agreements carried on between March and September 2022, until the Federal Cartel Office stepped in with a raid.
