Harman/Kardon BT – over-ear bluetooth headphones: gallery



Another participant in our recent A/B test of over-ear bluetooth headphones: Harman / Kardon BT. Nice design, expensive materials, good sound, decent battery life, but comfort could be better, the housing is quite microphonic, cables have non-standard plugs and you can’t use them while charging. Alas, no ANC either. More details coming in a few days in our review of Valco VMK20 that will include a comparison with a few other bluetooth headphones incl. the Harmans.
