thinksound ov21 Wired Over Ear Headphones - Pro Studio Monitor

In this review of the thinksound ov21 wired headphones the bottom line is simple: these are studio-minded, closed-back headphones built for listeners who want detailed, powerful sound and durable, sustainable materials. The review finds the ov21s especially compelling for recording artists, DJs and serious listeners because the 45mm dynamic drivers and closed design deliver a wide soundstage with strong low end while the detachable cables and memory foam ear cups make them practical for long sessions and mobile use.

Key Features

• 45mm Dynamic Drivers: Deliver authoritative bass and clear mids so instruments and vocals come through with studio-grade definition.
• Closed Back Design: Provides effective ambient sound isolation for tracking, mixing in loud environments, or focused listening.
• Detachable Tangle-Resistant Cables: Comes with two 4.5 ft cables, one with a mic and one without, making switching between recording and casual use painless.
• Comfort and Fit: Memory foam ear cups and an adjustable headband allow long sessions without heavy fatigue.
• Sustainable Bioplastic Components: Plastic parts are made with Eastman Trevaa bioplastic sourced from sustainably harvested wood to reduce distortion and improve tonal performance.
• Robust Connectors: 3.5mm steel reinforced gold plated plug increases reliability for repeated studio or stage use.

Who It's For

The ov21 is aimed at professional and discerning casual users: musicians, producers, studio engineers, podcasters and DJs who need a closed-back headphone with accurate reproduction and good isolation. Its wired connection and 50 ohm impedance suit audio interfaces, mixers and mid-power headphone amps common in project studios.

Less suitable are users who need true wireless freedom or active noise cancelling for commuting; while the ov21 isolates well passively, they do not offer ANC or a wireless option. Also, those who prioritize the absolute lightest earbuds for sports should look elsewhere.
