Common questions

How big is it?

It is 43.5 mm long with a maximum diameter of 8.2 mm, with 24 karat gold-plated contacts. It is RoHS compatible and sold as one piece.

When will it ship?

It is made to order and ships in 3 to 5 working days.

Does it keep the connection balanced?

No. A 3.5 mm output has three contacts, left, right and a shared ground, so the adapter gives you a single-ended connection. Learn more on player plugs.

Does what I needed it to do

While there was a slight hiccup with fulfillment (which was swiftly and painlessly resolved), this adapter does its job, allowing me to use my upgrade cable on standard 3.5mm audio outputs. The protective case it came in is a nice bonus.

Works as intended

It's a bit long, so your 2.5 TRRS on top of it would make the connection end look extended. Otherwise, it's sturdy and works.

works as expected

It turns your 2.5 balanced connector into 3.5 single ended. It makes the total length long, though.

Just works

This was the only adaptor that i could find that actually works Thanks very much Null Audio. Excellent.

Good but...

Very practical adapter, but I wish it would be more compact : a straight adaptor plus a strait plug makes a very long "plug".
Or making it L-shape, or flexible could solve that.

Works

It's a very simple adapter which surprisingly doesn't affect the sound too much (there is no adapter which doesn't affect the sound at 0), which is rather impressive for such an adapter. I can fully recommend this one.

Customer Service is top notch as usual - fast and very pleasant replies from Su.

Bought it together with Lune 2.5mm connector, so I can still use the cable when I connect my DAP to Mojo.

Null Audio 2.5mm Balanced to 3.5mm Coverter

Perfect for what I needed it for.

I found it difficult to source a converter that would allow me to use my dlalnced csabled iem with a single end output without changing cables.

This item is perfect and well made. I use it on my ibasso DX200.

Null Audio 2.5MM Balanced to 3.5MM SE Converter for Astell&Kern Players

It worked like a charm for my Onkyo DP-X1 player. It is slim n small, looks great too. A great buy at a good price. Highly recommended.

Works perfectly and feels solid!

Both my ciems and hifiman headphones are 2.5mm balanced terminated because I use my DP-X1's balanced out for them. I recently got my hands on a MoJo, so I needed a solution to convert 2.5mm to 3.5mm, and this adapter was perfect for that. It's short and feels solidly built. Kudos to Null Audio for a great product!

Awesome connector

I am having all my IEMs with 2.5 mm connection. So it is very difficult to change every now and then change the 2.5 mm cable with 3.5mm connection cable. To overcome this i order this connector. Build quality is awesome and really complement my 2.5mm cables without loosing the sound quality

Null Audio 2.5MM Balanced to 3.5MM SE Converter for Astell&Kern Players

Ordered this converter because I often change cables when pairing my custom in-ear monitors with different digital audio players. Some has 2.5MM output some doesn't. Now I just use this converter. It's very small, can be easy stored with in-ears inside Peli case.
