JOYO Studio Monitor Headphones, 50mm Drivers Over-Ear with Passive Noise Isolation, Flat Response for Recording/Mixing/Guitar Amp/Podcast, 3.5mm & 6.35mm Adapter (JMH-02) — Open-Box, 23% Off

50MM HIGH-FIDELITY DRIVERS — FLAT, ACCURATE SOUND FOR MONITORING: The JMH-02 features large 50mm neodymium drivers that deliver a flat, well-balanced frequency response (20Hz-20kHz)—the hallmark of a true studio monitor headphone. Unlike headphones that artificially boost bass, the JMH-02 reveals your mix exactly as it is: rich treble detail, smooth mids, and tight, un-hyped bass. Players describe it as budget friendly for mixing with a sound that rivals classic studio designs. PASSIVE NOISE ISOLATION — CLOSED-BACK DESIGN FOR FOCUSED LISTENING: The closed circumaural (over-ear) design naturally attenuates external noise by forming a seal around your ears—passive sound isolation, not active noise cancellation. Ideal for tracking vocals or instruments without headphone bleed into your microphone, or for focused listening sessions where you need to block out room noise. Note: This is passive isolation, not electronic ANC. 3M CABLE WITH 3.5MM & 6.35MM ADAPTER — READY FOR ANY DEVICE: A generous 3-meter straight cable gives you freedom to move around your studio, practice space, or stage. The included 6.35mm (1/4") adapter ensures secure, snag-free connection to guitar amps, audio interfaces, mixers, digital pianos, and drum modules. Compatible with any device sporting a standard 3.5mm or 6.35mm headphone output. SELF-ADJUSTING HEADBAND & PLUSH EARCUPS — BUILT FOR THE STUDIO: The lightweight self-adjusting leather-cushion headband and soft over-ear pads provide a comfortable fit for monitoring sessions, podcast recording, and practice. The flexible design accommodates a wide range of head sizes—from younger musicians to adults. For extended multi-hour sessions, we recommend taking occasional breaks, as ear pressure can build over time with any closed-back headphone. JOYO QUALITY & AFTER-SALES CONFIDENCE: Backed by JOYO's decade-plus reputation for crafting musical, budget-friendly gear. Each JMH-02 is tested before shipping. Should you experience any issues—especially channel imbalance, low output, or missing accessories—check the included manual for setup tips, or reach out to our dedicated support team through your Amazon order page. We stand behind every pair and are committed to making things right.

The JOYO JMH-02 is a closed-back studio monitor headphone built for accurate, flat-response listening in home studios, practice rigs, and podcast setups. Equipped with 50mm neodymium drivers, it delivers a well-balanced frequency response (20Hz-20kHz) that reveals every detail of your mix—rich treble, smooth mids, and tight, un-hyped bass. Unlike consumer headphones that artificially boost lows, the JMH-02 tells you exactly what your audio sounds like, making it ideal for mixing, tracking vocals and instruments, guitar amp monitoring, and critical listening where honesty matters. The closed circumaural design provides passive noise isolation by forming a seal around your ears, naturally attenuating external noise without electronic ANC—perfect for preventing headphone bleed into your microphone during recording sessions. The self-adjusting leather-cushion headband and plush over-ear pads offer a lightweight, comfortable fit, while the generous 3-meter fixed cable with included screw-on 6.35mm adapter keeps you connected to audio interfaces, guitar amps, mixers, digital pianos, drum modules, and any device with a standard 3.5mm or 6.35mm headphone output.

Quality Assurance:

Every JOYO JMH-02 is tested before shipping. For optimal performance, allow 20-30 hours of break-in time for the drivers to reach their full sonic potential. For best results with guitar amps, ensure the headphone output impedance matches the JMH-02's 32Ω rating. If you experience any issues—such as channel imbalance, unexpectedly low output, or missing accessories—first check that the 6.35mm adapter is fully screwed onto the 3.5mm plug (improper threading is the most common cause of connection problems). If problems persist, our dedicated support team is available through your Amazon order page. We stand behind every pair and are committed to making things right.
