Natural Portable Power House

Got it off sale, influenced by Andy #Donglemadness.
I must say this thing is powerful. Drives my Sundara Hiby Exclusive mode 28/100. Uncolored, everything's natural compared to my warm sources like ifi zen dac v2 and VE Megatron. Soundstage sounds clearer and wider. Great for analytical listening OTG.

Bit disappointed on audio format fixed on 16bit 96khz, means I hear noises when I use them for PC gaming. Its just me, but music listening wise its a beast.

I do recommend them if your IEM/HP are not bright leaning, or you want natural sounding, but only snag em when they're on sale. 2022 paying this for a full price its like paying for an outdated product, 150usd might as well get the Link2Bal. But for 75usd, its a bang for your buck for dongle that's uncolored and powerful.

Rafael Adonay

Excellent Dongle, the sound is very dynamic, articulate and authoritative for me, also very powerfull

Jean Breteau

Amplification capable de piloter un oppo 3 ( planar) sans difficulté.
Le dac AK se révèle de très
Il ne chauffe pratiquement pas
J'ai d'autres produits dragon,i basson,l'ovidius est clairement au dessus

Well worth the money

Gives the extra power needed for multi-driver BA IEM without muddying the sound at all. Well worth the money if you’re using the built-in DAC on your phone or don’t have a 3.5mm headphone jack available
