Review: Good performer, but pricy. - Nice little gadget. Very useful. Sound quality also good. 4.5k price shall be reasonable. 5k and Above not justified.
Review: Great for my purposes, simple and tiny! - Ok I went budget end as first time buying one if these. I had low expected tbh - but can say I am very surprised at how brilliant it is! It's tiny, and clips on easily to clothes. Very easy to set up and use. Super simple. Sound quality is better than I expected - though I'm no audiphole. I use this for podcasts and youtube, talking not music. Recommend!

### ⭐⭐⭐⭐⭐ Impressive versatility for the price.
*by A***T on 21 April 2026*

Fantastic product for wired headphones. This increases older headphones or wired audiophile headphones compatiblility. You can use them in more places. I use this with KPH30i and Koss Portapro and Bose SoundTrue II wired headphones from decade ago. This way when the battery of this device break eventually in number of years I don't have to just buy whole new set of headphones. I can just get this! The Range is impressive and mic is good. I work at a call center and use my Koss portapro wired with these on a laptop and iPhone at the same time. Dual connection works great. Optionally this FiiO product gets software updates with the iPhone or android fido app. The latest update is supposed to fix (4-2026) is supposed to fix the volume sensitivity so that the lowest volume can be lower. Definitely worth the 20 bucks and it's from an Audiophile brand you know is going to give you good quality for the price. I mean LDAC for 20 bucks! Very nice a small and easy to use controls on any wired headphones with 3.5mm jack add basically add mic to headphones without one too. Great LDAC quality sound.
