Earmax IE80S Bluetooth Headphones

The low-frequency fine-tuning function is very practical. The principle of adjustment is to change the air flow inside the sound cavity. There are a total of five gears to choose from. At the minimum gear, the air holes are closed and the airflow movement in the cavity is restricted, so the low frequency is minimal at this time. As the gear position increases, more conversion air enters the cavity, making the low frequency more active and improving the sense of volume. specification Wearing method: in-ear Functional use: mobile phone headphones, music headphones Frequency response range: 10Hz-20KHz Product impedance: 16 ohms Connection method: 3.5mm plug Sound principle: moving coil Driver unit: 14.3mm Frequency response range: 10Hz-20KHz Product impedance: 16 ohms Sensitivity: 116dB Rated power: 40mW Headphone cable: 1.2m Product weight: 5g
