• a first dipole loudspeaker built into the left temple piece of the frame, wherein the first dipole loudspeaker comprises a first driver that emits front-side acoustic radiation from its front side and into a front cavity of the left temple piece, wherein the front cavity is located directly in front of the front side of the first driver, and rear-side acoustic radiation from its rear side, wherein the left temple piece of the frame comprises a first sound-emitting opening that is configured to emit front-side acoustic radiation from the left temple piece of the frame and a second sound-emitting opening that is configured to emit rear-side acoustic radiation from the left temple piece of the frame, and wherein when the frame is worn on the head of the user the first and second sound-emitting openings of the left temple piece are both configured to be located in front of the left ear of the user with the first sound-emitting opening closer to the ear canal opening of the left ear than is the second sound-emitting opening;
• wherein the front cavity of the left temple piece is fully defined by the front side of the first driver, a first wall of the left temple piece located directly opposite the front side of the first driver, and a second wall of the left temple piece that extends entirely around the first driver;
• wherein the first sound-emitting opening is in the second wall of the left temple piece and is configured to emit front-side acoustic radiation from the first driver directly from the front cavity of the left temple piece into the environment;
• a second dipole loudspeaker built into the right temple piece of the frame, wherein the second dipole loudspeaker comprises a second driver that emits front-side acoustic radiation from its front side and into a front cavity of the right temple piece, wherein the front cavity is located directly front of the front side of the second driver, and rear-side acoustic radiation from its rear side, wherein the right temple piece of the frame comprises a third sound-emitting opening that is configured to emit front-side acoustic radiation from the right temple piece of the frame and a fourth sound-emitting opening that is configured to emit rear-side acoustic radiation from the right temple piece of the frame, and wherein when the frame is worn on the head of the user the third and fourth sound-emitting openings of the right temple piece are both configured to be located in front of the right ear of the user with the third sound-emitting opening closer to the ear canal opening of the right ear than is the fourth sound-emitting opening;
• wherein the front cavity of the right temple piece is fully defined by the front side of the second driver, a first wall of the right temple piece located directly opposite the front side of the second driver, and a second wall of the right temple piece that extends entirely around the second driver;
• wherein the third sound-emitting opening is in the second wall of the right temple piece and is configured to emit front-side acoustic radiation from the second driver directly from the front cavity of the right temple piece into the environment.
