The device (K) has a head clip comprising head clip halves (KH, KH'), and electro-dynamic drivers e.g. miniature loudspeaker casings (L, L'), arranged within acoustic damped housings (A, A') at ends of the head clip halves. One of the halves (KH) is made of thermoplastic material e.g. polyamide, and has a hollow chamber (D), which is acoustically connected with one of the damped housings (A) via a spacer (B). The chamber is acoustically effective for one of the electro-dynamic drivers (L). The spacer is designed as a hollow-shaped angular piece. An independent claim is also included for a system that comprises a signal processing unit. |
