Sennheiser has been busy in 2024 and has already launched several new wireless headphones, including the five-star Momentum True Wireless 4.
At High End Munich 2024, the company has unveiled yet another new pair. The HD 620S are a new addition to Sennheiser’s much-loved HD 600 range, but instead of being open-backed, which has been the norm for this range, they are actually a closed-back design.
