Weird to release closed backs as open back successors but given that the HD600 series really isnt all that wide in the first place i guess thats not too big of a deal. Response looks alright but bass boosted and theres a weird lil hump at 500-900hz, not sure how much thats going to be heard.
The HD 620S is Sennheiser's latest pair of wired and closed-back headphones. Designed with audiophiles in mind, the Sennheiser HD 620S is already available to pre-order in multiple markets.
