OpenRock Link 20 Review: Magnetic Mic Earbuds Built for Professionals

The OpenRock Link 20 promises something no other earbuds currently offer: the world's first open-ear earbuds with detachable magnetic microphones. With N54-grade magnets, MagShield™ FusionTech, and durability tested to 10,000+ mic detachments, OpenRock aims to reinvent communication on the go.

But does this innovation make sense for everyday users, or is it a niche tool for professionals? After thorough testing and feedback from the OpenRock team, here's the full verdict.

Why the Futuristic Design Doesn't Always Work

The Link 20 scores points for innovation, but it comes with trade-offs. The open-ear design lets you stay aware of your surroundings, a benefit for office workers or commuters. However, its slightly bulky appearance may deter those looking for minimalist earbuds.

That said, the case's dimensions (104×52.6×27.5mm) are deliberately engineered to accommodate the built-in boom microphone, a key feature that delivers crystal-clear call quality across a range of environments. In real-world terms, the case's footprint is smaller than a smartphone and comparable to a standard matchbox or key fob, keeping it reasonably portable for daily use.

The premium-grade plastic build feels sturdy, and the rubber casing around the earpieces adds comfort. While the charging case could offer better grip, it's not unwieldy and holds up well for professionals who value functionality over pocket-size convenience.

How the Detachable Magnetic Mic Enhances Calls

The detachable magnetic microphone is the Link 20's defining feature, and it works brilliantly. Attaching and detaching the mic is quick, secure, and intuitive. Once connected, the difference is clear: voice quality improves significantly, making it ideal for video calls, hybrid meetings, or trading floors where clarity matters most.

The earbuds connect via Bluetooth seamlessly, requiring no fiddly setup. For professionals who value smooth, interruption-free communication, this feature is a standout asset.

Performance in Daily Use: Reliable and Surprisingly Secure

OpenRock's design underwent rigorous testing, including running and gym workouts, to ensure a secure and comfortable fit. Despite the open-ear structure, the ergonomic shape proved stable in standard running tests, with no instances of slipping or falling off.

That said, those engaging in high-intensity or movement-heavy sports may still find the design less snug than fully in-ear options.

With the mic attached, the Link 20 delivers dependable call quality, voices sound crisp and natural, and the open-ear style avoids the blocked feeling common in traditional earbuds. Music playback is serviceable but clearly secondary to its communication-first purpose.

Why Durability Impresses but the Case Still Divides Opinion

Durability is where OpenRock's engineering shines. The six-layer noble metal plating and sweat- and corrosion-resistant build ensure the mic system is built for long-term use. The N54-grade magnets, tested for 10,000+ detachments, remain strong and stable over time.

The earpieces themselves are reinforced with a rubberised casing, which enhances comfort and resilience during daily use. However, while the charging case offers reliable protection, some users may still find its finish a touch slippery.

Who Will Love the User Experience (and Who Won't)

The Link 20 is clearly tailored for professionals. Corporate users, traders, and telecallers will appreciate how the detachable mic elevates clarity. Switching between mic-on for meetings and mic-off for music feels intuitive.

Fitness enthusiasts, on the other hand, may find the open-ear design less ideal for intense workouts. It performs well for jogging or light gym sessions but isn't optimised for high-motion sports.

Overall user experience? Smooth for work, decent for fitness, and excellent for calls.

Why the Price Now Feels More Justified

Originally priced at $149.99 (£129.68), the Link 20 is currently available at an early-bird discount of 30–50% during OpenRock's crowdfunding campaign. This makes it significantly more accessible than competitors such as Jabra, Poly, and Shokz, especially considering the advanced active AI ENC noise cancellation, multi-mode functionality, superior battery life, and improved IP rating for water and dust resistance.

For professionals who spend hours on calls, the price feels competitive and justified. For casual listeners or gym-goers, it's still a premium buy, but one backed by innovation and craftsmanship.

Pros and Cons at a Glance

A Smart Buy for Heavy Callers, Not Runners

The OpenRock Link 20 is a thoughtful innovation in the world of earbuds. By combining an open-ear design with a detachable magnetic mic, it creates a communication-first tool unlike anything else on the market.

For corporate professionals or anyone who lives on calls, the Link 20 is a genuine game-changer. For fitness enthusiasts or casual users, however, the trade-offs in portability and versatility mean better all-round options exist.
