Koss CL20i Transparent On-Ear Headphones with Mic

Koss CL20i are lightweight, clear-shell on-ear headphones with an in-line microphone and remote that deliver balanced sound and retro style for everyday listening.

These transparent on-ear headphones blend a vintage-inspired look with modern convenience: soft leatherette ear cushions, a 3.5mm wired connection for wide device compatibility, and simple call/music controls built into the cable. The see-through housing gives them a distinctive visual character while keeping the design practical and portable for commuters, students, and anyone who prefers a wired audio connection.

How do the Koss CL20i feel during long listening sessions?

The CL20i prioritize comfort through lightweight construction and plush leatherette ear pads that sit gently on the ears without overly isolating you. Their on-ear fit reduces clamping pressure while remaining secure for walking or casual use.

• Featherlight frame minimizes fatigue for extended wear
• Plush leatherette cushions provide soft contact and moderate passive isolation
• Compact, fold-flat friendly profile for storage in bags

What controls and call functions are included on the cable?

The in-line microphone and remote let you handle calls and basic playback without reaching for your device. One-button call control supports answer/end calls and play/pause on most smartphones; the microphone picks up speech clearly enough for everyday conversations.

• Built-in mic for hands-free phone calls
• One-touch remote for play/pause and call handling
• Compatible with many iOS and Android devices (3.5mm jack required)

How does the CL20i perform acoustically?

Koss tuned these on-ear drivers to cover a broad 30–20,000 Hz range, giving a balanced response suitable for podcasts, pop, acoustic tracks, and casual gaming. They aim for clear mids and manageable bass rather than heavy low-end emphasis, which keeps vocals and instruments natural.

• Wide frequency coverage for varied listening genres
• Balanced tonal profile emphasizes clarity over bass boost
• Wired 3.5mm connection preserves signal fidelity without battery dependency

Will the CL20i work with my phone, tablet, or laptop?

Yes — the CL20i use a standard 3.5mm plug, so they connect directly to most smartphones, tablets, laptops, gaming handhelds, and audio players that include a headphone jack. No pairing or charging is necessary, making them convenient for travel and shared-device use.

• Standard 3.5mm plug for broad device compatibility
• No batteries or Bluetooth setup required
• Works with adapters for devices without a headphone jack

Who is this for? The Koss CL20i suit listeners who want a distinctive, transparent retro aesthetic combined with dependable wired performance and simple hands-free controls. They are ideal for commuters, students, and anyone who prefers a plug-and-play headphone with a comfortable on-ear fit and clear, balanced sound.
