Grado 6.3mm to 3.5mm Jack Adapter

The Grado mini adapter takes a 6.3mm jack plug down to a 3.5mm socket – so your Grado headphones also work with devices that have a small headphone output.

An unassuming part that you always end up looking for exactly when you don't have it: on a laptop, a portable DAC, a mixing desk.

Why the original adapter?

It's wired with four conductors, preserving the signal path of Grado cables instead of combining ground returns. On top of that comes a solid plug connection – a point where cheap adapters regularly fail, showing up as a loose contact or a channel dropping out on one side.

What you get

A compact, cleanly built adapter from the Grado range. Plug it in and listen – honestly, there isn't much more to say.

Who is the adapter for?

For anyone with a Grado headphone with a 6.3mm plug that needs to run from a 3.5mm output. Straight talk: it doesn't turn a demanding headphone into a portable one – volume and control still depend on the source, not the adapter.

Our verdict

Small part, small price, big hassle when it's missing. Best kept right alongside the headphones.

Frequently asked questions

Does the adapter fit every Grado headphone?

It fits any Grado with a 6.3mm jack plug, so most wired models in the Prestige, Reference, Statement and Signature lines. Models that already ship with a 3.5mm plug and separate adapter don't need it. If you're unsure, just tell us your model.

Does the adapter cost me any sound quality?

Practically not, with a clean plug connection. What matters is contact quality, and that's exactly where cheap adapters cut corners. Audible problems like crackling or a dropped channel almost always come from poor contacts, not from the adapter principle itself.

Why buy the adapter from HD Zürisee?

Because we can tell you right away whether the adapter actually solves your problem, or whether a headphone amp would help more. HD Zürisee in Wädenswil also advises on small parts – and ships them together with the rest of your order.
