Product details

Wireless freedom with a retro twist

Meet the Koss KPH30 Wireless headphones, where timeless retro styling meets modern wireless listening. The Stealth Gray finish nods to classic design while delivering a practical on-ear fit built for daily use.

Sound that fits your day

Experience clear, balanced sound across a broad 15–25,000 Hz range, with rich mids, crisp highs, and a sense of presence that enhances music, podcasts, and video content.

  • Wide frequency range for detailed highs and warm lows
  • Personal listening that stays focused on your content

Power that keeps going

With 20+ hours of battery life on a single USB-C charge, you can enjoy hours of listening through commutes, study sessions, or long flights. A quick recharge brings you back to listening sooner, depending on usage.

  • Up to 20+ hours of playback per charge
  • USB-C fast charging for broad compatibility

Control at a glance

Built-in controls and a microphone simplify everyday use. Adjust volume, skip tracks, pause, launch your voice assistant, or manage calls without reaching for your device.

  • Volume, track changes, play/pause, and call handling at your fingertips
  • Integrated microphone supports hands-free calls and voice prompts

Versatility you can feel

Need wired or mixed use? The KPH30 supports a USB-C to 3.5 mm wired connection with the KUSB-50 Analog Pass-Through cord (sold separately), useful for gaming, editing, or quiet listening when wireless isn’t ideal.

  • Optional KUSB-50 cord enables USB-C to 3.5 mm wired connection
  • Lightweight, durable design for daily wear and travel

Designed for long-lasting comfort with a striking retro silhouette, the KPH30 Wireless blends nostalgic style with practical features to fit your listening routine. The Stealth Gray finish offers a versatile, understated aesthetic for any setting.
