Studio monitoring with 50 mm drivers

The MXL HX9 is a closed-back, over-ear headphone built for studio monitoring and content creation. Its 50 mm drivers deliver full-range detail and clarity across the frequency spectrum. The earcups integrate both 3.5 mm and 6.35 mm inputs so no separate adapter is required. A detachable cable and foldable frame make the set easy to transport between sessions.

Comfort and cabling for long sessions

The lightweight, foldable construction reduces fatigue during extended recording or editing periods. A detachable cable with dual-sided adapters plugs into either earcup, letting you route the lead away from your workspace. The closed-back design isolates the listener from ambient noise while preventing microphone bleed. An included carrying pouch protects the headphones when stored or moved between locations.

Daisy chain input for multiple listeners

A dedicated daisy chain input allows several HX9 units to connect to a single audio source for group monitoring or collaborative review. This feature is specific to the HX9 and is not common on standard studio headphones. Buyers who need wireless connectivity or active noise cancellation should look elsewhere, as the HX9 is a passive wired design. The package includes the headphones, detachable cable with 3.5 mm and 6.35 mm ends, and the MXL carrying pouch.

Questions about this item

How much heat or noise do the 50 mm drivers produce during all-day studio sessions?

The closed-back design and 50 mm drivers are built for extended listening, and the headphones are passive so they generate no fan noise or electrical heat themselves.

What audio source connections must I already have to use the dual 3.5 mm and 6.35 mm inputs on the earcups?

You need a device with either a 3.5 mm or 6.35 mm headphone output; the detachable cable includes both plug sizes so no separate adapter is required.

Will the daisy-chain input work with older studio gear that only has a single headphone jack?

Yes, the first pair plugs into the source and each additional HX9 connects to the previous pair’s daisy-chain port, letting multiple listeners share one output.
