SIVGA Que Tested and working. Price negotiation not accepted. 10mm Beryllium Diaphragm Dynamic Driver Impedance: 32Ω Sensitivity: 108dB +/-3dB Frequency Response: 20Hz ~ 20KHz Cable Specifications: Cable Length: 1.25m Cable Material: Silver-plated high-purity oxygen-free copper wire Connector: 0.78mm 2PIN Plug: 3.5mm Used for a short time, I think the condition is good, and it has been tested and confirmed to be working. The box and ear tips are also included. I think this is a really good sounding earphone for the price. It has the attack you'd expect from beryllium, and the sound is natural. Thank you very much. shure Sennheiser Wired Piyahon Wired Earphones sony Audio-Technica letshuoer Monitor
