Ruth's sister international power cord 3.5mm 300cm

SKU CH-90CT-BEFB6

A 3.5 mm wired in-ear monitor headphone with a 300 cm cable for live broadcast and mobile use

  • 300 cm cable gives freedom of movement during broadcasts
  • 5 mm plug fits phones and devices with standard jack
  • Orthodynamic driver delivers HiFi stereo with powerful bass
  • Sealed in-ear design isolates environmental noise effectively
  • Durable plastic and metal build withstands daily wear

Product identity

This wired in-ear headphone uses a 3.5mm connector and a 300cm cable to deliver audio to mobile phones and other devices with the same jack. The orthodynamic driver design targets monitoring and live-broadcast use where a stable, tethered signal is preferred.

Build integration

The 3.5mm plug fits any standard headphone socket, so no adapter or separate power source is required. A three-metre cable removes the need to sit close to the source device, freeing movement for performers, camera operators or presenters.

Sustained behaviour

Sealed earcups and passive isolation maintain consistent sound quality during extended sessions without the pressure buildup that open designs can cause. The wired connection avoids the latency drops or battery fade that wireless alternatives exhibit over long periods.
