Third-party reviews

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

What we like about Sennheiser HD 2 20S

  • Lightweight and portable design for on-the-go use
  • Thumping bass and punchy low-end response
  • Fairly well-controlled high-end clarity
  • Includes a built-in microphone and smart remote for calls
  • Comfortable leatherette earpads that are suitable for glasses wearers
  • Good value for the price point
  • Effective passive noise isolation for an on-ear design

What we don't like about Sennheiser HD 2 20S

  • Lack of detail in the midrange and lower frequencies
  • Bass can sometimes sound fuzzy or bleed into the vocals
  • High clamping force may cause ear fatigue during long sessions
  • Thin, non-detachable cable that is prone to tangling
  • On-ear fit does not create a complete seal, allowing some ambient noise
  • Foldable mechanism is not as compact as previous models like the PX 100-II
  • Plasticy build quality that feels less than premium

Verdict

The Sennheiser HD 2.20S is an ultra-lightweight, entry-level closed-back on-ear headphone designed for portable use with smartphones and tablets. It features a folding headband for compact storage, a single-sided 1.4-meter cable with an integrated one-button remote and microphone, and 26-ohm impedance optimized for mobile devices. Key specifications include a frequency response of 18–18,000 Hz, a sensitivity of 112 dB SPL, and a weight of approximately 246 grams. Main pros include its highly portable collapsible design, strong bass response with detailed highs, and a comfortable, secure fit for smaller head sizes. However, notable cons include sound isolation issues where ambient noise may leak in or out, a fixed (non-detachable) cable that is prone to tangling, and potential discomfort or pinching during long listening sessions due to the plastic headband and lack of size adjustment.
