These full-size on-ear headphones use state-of-the-art drivers mounted in natural wood cups, designed to create a perfectly optimized acoustic space.

This is possible thanks to an extremely precise and reliable system.<\/p>\n<p>The Palma DHS-1 earcups are made from sapele, a type of wood prized for its excellent acoustic qualities, used in the production of musical instruments. Thanks to its resistance to wear and easy precision machining, the DHS-1 earphones provide the dynamics with an optimal acoustic load, so that the frequency response is virtually flat in both open and closed modes of operation, ensuring maximum musicality at all times, regardless of the volume level. It uses broadband electrodynamic heads with a 50 mm diaphragm made of a mixture of pressed cellulose in its central part and an ultra-thin polyamide suspension ring.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/www.stereoindex.com\/tech\/wp-content\/uploads\/2024\/07\/26_techweek.webp\" alt=\"\u00a0 Palma DHS-1 Over-Ear Headphones\" \/><\/p>\n<p>To achieve the duality, the outer sides of the Palma DHS-1 earcups combine precisely calculated circular perforations &#8211; in the &#8220;golden ratio&#8221; &#8211; with a movable outer aluminum cover that acts as a shutter, thus achieving the freedom of open mode operation and the high level of isolation typical of closed headphones. The user only needs to rotate the outer covers of the shutters by 14 degrees, like the visor of a motorcycle helmet &#8211; back to switch from closed to open mode or vice versa to switch from open to closed mode.
