S66
The 6.5-foot cord provides extended reach for stationary use, while the built-in volume control allows direct audio adjustment without touching the source device. Interchangeable ear tips and a lightweight 41g build prioritize a comfortable fit for prolonged wear. These are best for TV viewers or tablet users who need a simple, wired audio solution without a microphone.
