okcsc Retro 3 On-Ear Headphones 40mm Open-Back

These are okcsc Retro 3 on-ear headphones: lightweight, foldable retro-style cans with 40mm drivers and a built-in mic for clear hi‑fi listening on commutes, work, and travel.

The okcsc Retro 3 blends vintage looks with modern sound engineering. Its 40mm open-style drivers and 58 Ω impedance aim to reproduce music with natural spatial character, while the adjustable on-ear pads and collapsible metal frame keep it portable. Supplied with multiple earpads, a storage pouch, and a 3.5mm mic cable, this model targets users who want stylish, comfortable headphones for everyday listening rather than noise-isolating studio monitoring.

How does the Retro 3 sound compared to earbuds or closed-back headphones?

The Retro 3 uses open-backed 40mm transducers to create a more speaker-like soundstage, so instruments feel more separated and airy than in most closed or in-ear designs. With a higher impedance of 58 ohms, the headset reduces electrical noise and preserves finer audio details when paired with phones or portable amps that can drive it.

• Open-back design for wider sound dispersion and natural imaging
• 40mm drivers tuned for clarity and midrange presence
• 58 Ω impedance to minimize distortion and preserve dynamics
• Best suited to sources with moderate output capability for full effect

How portable and durable is the folding mechanism?

The Retro 3 features a collapsible metal-accent frame that folds flat, making it easy to slip into a bag or pocket. At about 65 grams, the headphones are notably lightweight, and the metal fasteners add structural strength without becoming bulky.

• Metal hinges for stable folding and compact storage
• Lightweight construction (approx. 65 g) for carry comfort
• Included storage pouch protects the headset on the go
• Designed for daily commuting, travel, and quick stowaway

Will these be comfortable for long listening sessions?

On-ear temporal pads are adjustable to fit different head sizes and help keep weight off the ears. The package includes six replacement earpads in random colors so you can refresh cushioning or personalize the look. Because they sit on-ear rather than around it, comfort will depend on individual preference and ear shape.

• Adjustable headband and on-ear pads for tailored fit
• Six replacement earpads included for customization and longevity
• Low overall weight reduces listener fatigue during extended use
• May leak sound at higher volumes due to open-back design

How does the microphone and cable setup work for calls or streaming?

The Retro 3 arrives with a 4.9 ft (approx. 1.5 m) cable terminating in a 3.5mm plug and an inline microphone, enabling hands-free phone calls and voice chats. The wired connection avoids latency and keeps compatibility broad across phones, laptops, and portable players that accept a TRS or TRRS jack.

• 4.9 ft cable length for flexible movement during calls
• 3.5mm plug for universal device compatibility
• Inline mic supports clear voice pick-up for calls and meetings
• Wired design eliminates Bluetooth pairing and battery needs

Who is this for? The okcsc Retro 3 is aimed at style-conscious listeners who favor a retro aesthetic and want a portable, airy-sounding on-ear headset for daily use. It fits commuters, students, casual audiophiles, and anyone who values lightweight design, replaceable pads, and a built-in mic over heavy noise isolation or studio-grade monitoring.
