Adapter Moondrop UP! — 4‑pin XLR (male) to 4.4mm Balanced TRRRS, 30 cm cable

The Moondrop UP! adapter converts a 4‑pin XLR headphone output to a 4.4 mm balanced TRRRS plug using a short 30 cm cable. This passive adapter preserves balanced signal wiring without active electronics, enabling direct connection between studio or headphone amplifiers and headphones or cables that use a 4.4 mm balanced socket. Its compact form factor and fixed cable length make it suitable for desktop and portable setups where a reliable, low-footprint adapter is needed.

Advantages

The adapter provides a direct, passive conversion that maintains balanced left and right channels and ground separation, avoiding the need for bulky adapters or custom cables. With a 30 cm cable it offers enough reach for typical desktop use while keeping signal path length minimal to reduce potential interference. As a passive solution it requires no power or drivers and is compatible with standard balanced headphone wiring schemes.

Suitable for

• Connecting professional headphone amplifiers or studio outputs with 4‑pin XLR to headphones with 4.4 mm balanced inputs
• Desktop audio setups where a short, tidy connection is preferred
• Mobile or portable players and DAC/amps that provide a 4‑pin XLR output
• Audio testing and comparison when using equipment with different balanced connector standards

Key specifications

• Connector A: 4‑pin XLR (male)
• Connector B: 4.4 mm balanced TRRRS (female plug)
• Cable length: 30 cm (fixed)
• Wiring: passive balanced wiring, no active components
• Construction: compact adapter with short molded cable for strain relief

How to use

Insert the 4‑pin XLR male into the source or amplifier output and plug the 4.4 mm balanced TRRRS into the headphone or cable input. Ensure connectors are fully seated to maintain proper contact for left, right and ground connections. No additional configuration, power, or software is required. Disconnect by pulling the connector body rather than the cable to avoid stress on the joint.

Usage recommendations

Use the adapter in environments with minimal mechanical strain on the short cable; avoid sharp bends near the connector ends and disconnect by gripping the connector shells. For long-term stationary installations, consider routing the cable to minimize tension. If uncertain about wiring compatibility, verify pinouts of your equipment to ensure standard balanced assignments.
