Headphones with two-way cable

 

— headphones in which a wire is connected to each “ear” separately (the cable for this is usually bifurcated closer to the headphones, and sometimes at the plug itself).

This cable entry is somewhat less convenient than one-way, since the wire is more prone to tangling; however, it is also quite popular. First, the reversible design is actually the only ear option available that doesn't have a headband, headband, or neck mount. Secondly, the separation of wires reduces their influence on each other and reduces the likelihood of interference; thus, this option is considered optimal for high-end hi-fi and hi-end headphones.
