The Hi‑X55 is engineered to deliver exceptional sound quality and durability in a closed‑back, over‑ear form‑factor. With proprietary “Hi‑X” high‑excursion drivers, solid construction and detachable cable, this headphone serves mixing, tracking and discerning listening with confidence.

  • Closed‑back design: excellent isolation, suitable for environments where controlling bleed and ambient noise matters.
  • Low impedance (25 Ω) combined with high sensitivity (118 dB SPL/V) means it can be driven by interfaces, laptops or mobile equipment with ease.
  • Detachable 3 m cable with 3.5 mm plug plus included 6.3 mm adapter.
  • Robust build: metal hinges and headband, foldable construction for portability and storage.

Technical Specifications

  • Impedance: 25 Ω

Suitable For

  • Mixing engineers and producers who need high‑fidelity closed‑back monitoring.
  • Artists tracking in loud or untreated spaces where isolation is important.
  • Mobile creators who want professional sound on portable rigs without bulky setups.
  • Serious listeners who prioritise build quality, serviceability (replaceable cable/pads) and reliability over hype sound.

Why It’s a Strong Choice

The Hi‑X55 stands out because it balances studio‑grade features with real‑world usability. The low impedance means you can drive it easily from many sources. The robust build and foldable design make it practical for both studio and mobile use.
