Disclaimer - I bought this set of IEM out of my own pocket money, and all impression is entirely based on my own listening and understanding.
Unboxing and Presentation
Ordered this one from TaoBao and was pleasantly taken by surprise from the packaging and unboxing experience.
The packaging is very similar to the recent MoonDrop Aria 2 that i have bought.
The box itself has a magnetic flip open and 'Wala' the set of well built from metal alloy IEMs is there.
The package comes with a cloth zipper pouch, cloth woven cable with mic, 9 sets of silicon tips in S, M & L sizes.

Sound
Tonality - Bright Mid Centric Vocals Good Treble Extension Details.
Bass - Fast and tight mid bass, not so much emphasis on low sub bass or that rumbling Basshead loves.
Mids - Male and Female vocals are a real joy on this set, clean clear and forward sounding.
Treble - Extend very well and treble details are very clear and clean on the wind, chime and string instruments.
Soundstage - Wide and spacious sounding, width, depth and height is adequate enough.
Comparison
Against Moondrop Aria 2 OTTB No Mod stock - Aria sounds a little veiled and recessed, tonality and timbre is more natural sounding.
Against Whizzer OS1Pro OTTB No Mod stock - OS1Pro is balanced sounding but not as engaging fun listening pleasure as compared.
Conclusion
The Reecho SG01 is a low budget, very good value over performance set, for Mid Centric Vocals Lovers [ both Male and Female] and Treble Details Extension Lovers.
Overall sound impression is impressive, well built metal alloy shell, light and good fit and isolation. For low budget set, the accessories supplied is the best i have encountered so far.
I must congrats Reecho on this set for the outstanding performance over value i have seen till date in 2021.
