Aluminum drivers eliminate RF frequencies at the source. A 5-inch hollow air tube routes only acoustic waves — no electrical current, no electromagnetic field — to your ears. The driver sits inside a sealed chamber at the bottom of the 42.5-inch cord, converting electrical signal to sound before it ever enters the tube.\u003c\/p\u003e\u003cp\u003eNo Bluetooth. No battery.
