I first thought that the customizable switches were a gimmick. But they're not. My favourite setting is 'Detail'. It's incredible the detail and nuances that this IEM brings to the table. But the USP for me is the ultra-wide Soundstage. I haven't heard that on any other IEM.

If you’re looking for a comfortable IEM with switches to slightly tweak the sound, a nice build quality, I totally recommend getting the 1Custom Junior IEMs from them.
The stock tonality of the Junior is on the slightly brighter side, but it does offer a smooth bass region and a euphonic midrange with a wide soundstage.
The 1Custom Junior from Jaben Singapore has an excellent value. The Bass is quite beautiful, with an excellent amount of impact, a nice sub-low extensions, mid-bass presence too.
