Headphones with increased security and triple function with adaptable equalization

Enhanced safety headphones, comprising:

• two niches (2) with earpieces that can be interchanged by the wearer as desired, comprising three different earpieces for each ear, to be used according to the different operating conditions, where no, medium or high sound isolation is necessary;
• a loudspeaker (11) disposed inside each niche (2);
• two bone conduction earpieces, each of which comprises a front part (13), an equalization circuit (14) capable of connecting to a connector (10), and a membrane (12) to adapt the acoustic impedance of the headphones to the loudspeaker (11), wherein the circuit (14) is capable of equalizing the audio listened to by eliminating bass tones;
• each earpiece is removably connected to a niche (2);
• two earpieces to be placed at least partially inside the ear, each of which comprises an external structure (21) provided with an equalization circuit (20) capable of being connected to the connector (10), and an adaptor (22) made of soft material capable of adapting to the ear canal;
• the circuit (20) is capable of reducing the output audio level to values ensuring the safety of the ear;
• each earpiece is removably connected to a niche (2);
• two earpieces covering the outer ear, each of which comprises an external structure (34) made of soft material capable of resting on the outer ear, a connection interface (31), configured to be removably connected to a niche (2), a membrane (32), a cover (33) and an equalization circuit (30), configured to be connected to the connector (10) and achieve a predetermined equalization of the audio;
• each earpiece is removably connectable to a niche (2).
