Don Scorpio Dolphin
I spent 8 months of my life in China last year and also spent my free time going around in the most incredible place worldwide for electronics gear.
The Shenzhen Electronic market
I bought one sample after try many kinds of headphone copy or original one's. I never know Don Scorpio brand and never try this product before but in just 5 seconds play a song from my Iphone ( that can't be a reference in audio quality!) and simply I love it. So finally I completely agree the Vectron opinion. Surely better than high end headphone made by AKG, not at same level of better Sennheiser, but sure 100% that the value of this head phone is may be 4 time the money spent ( if you have as reference the 120 usd price).
Just a remarks, in China cost only 30€.
Regarding the materials quality, no dubt some detail can be better made, but never forget the price and the value of 2 way excellent driver that really can give you a timeless pleasure.
Chinese can make it perfect in some details but the price will be higher for sure (believe me I do this job everyday)
