Third-party reviews

Based on ratings from across the web.
Reviews last updated: November 2026 · How we calculate this

What customers like about Sennheiser RS 120 II

  • Lightweight and comfortable for long-duration TV watching
  • Excellent wireless range that works through walls and across multiple floors
  • Detailed and clear sound reproduction, particularly well-suited for dialogue
  • Simple setup and intuitive volume/tuning controls on the earcup
  • Convenient charging cradle that doubles as a storage stand
  • User-replaceable standard AAA rechargeable batteries extend product lifespan

What customers don't like about Sennheiser RS 120 II

  • Susceptible to RF interference and background static hiss
  • Manual tuning wheel can be finicky to find the clearest signal
  • Blasts loud static if the transmitter auto-shuts off due to low audio signal
  • Lacks deep bass response compared to higher-end or wired models
  • Loose fit can cause them to slide off if the user bends down
  • Build quality feels somewhat plasticky or flimsy to some users

Verdict

The Sennheiser RS 120 II is an open-back, supra-aural wireless RF headphone system designed primarily for high-fidelity TV and music listening. It features a frequency response of 22 Hz to 19,500 Hz, an impedance of 24 Ohms, and a maximum sound pressure level of 106 dB. The system includes a multi-purpose transmitter that doubles as an easy-access charging cradle for the included NiMH AAA batteries, which provide up to 20 hours of operation per charge. Key advantages include its lightweight 230g build for long-term comfort, a broad wireless range of up to 100 metres that functions through walls, and intuitive on-ear controls for volume and tuning. However, notable drawbacks include a persistent low-level background hiss characteristic of analog RF transmission, the requirement of manual frequency tuning to avoid interference, and a loose fit that may cause the headset to slip if the user tilts their head.
