View Full Discussion You can also buy this, they have a 3.5 version, so you can use your existing 3.5mm cables with the balanced port, although I'm unsure what benefit it would have, since 3.5 isn't balanced. Maybe just higher gain.
Edit: I just noticed this cable is only 1.2m! $50 for unusable length, it's a joke. 👎
I would stay away from such adapters. Specially when used in fully differential headphone amps.
Even a 2.5mm to XLR? I'm not sure what could go wrong.

My comment was specific to this bit.
3.5mm can be balanced Ifi used to favor this connector. Whether or not something can or cannot be balanced is determined by the number of connection points available and the number of channels. For stereo headphones the minimum is 4, like a 4-pin XLR or TRRS (in 2.5 or 3.5mm diameter). To carry stereo balanced signals between two components the minimum is 5 but 6 is needed to have a dedicated ground per channel.
This is why many portable devices do not recommend you run their 2.5mm TRRS headphone outputs as balanced line outputs, a TRRS connector has only 4 connections, fully balanced stereo source gear has 6. The 4.4mm pentacon resolves this issue with having 5 points available (TRRRS), allowing the same connector to be used for headphone or line output.
