I have heard and/or owned all of them now starting from the original Sunrise Audio SWD from c2010 all the way up to the latest released model the SWD3+ and they have progressively gotten better with each model release. I didn't really care for the first two early models which I found to be shouty and harsh (quite aggressive) and they were quite excited which really wore me out. It wasn't until I heard the SWD2+ that I started to appreciate their signature and started recommending them though be warned they are treble leaning (slightly bright). The SWD2+, SWD2LE, SWD3, and the new SWD3+ all exhibit a slightly naughty sharpness in the treble area which I personally still find to be quite fatiguing.
2021 - Simphonio SW-Dragon 3 Plus (120Ω; aka "SWD3+")
2020 - Simphonio SW-Dragon 2 Limited Edition (120Ω; aka "SWD2LE")
2019 - Simphonio SW-Dragon 3 (150Ω; aka "SWD3")
2017 - Simphonio SW-Dragon 2 Plus (16Ω; aka "Sunrise Audio SWD2+")
2012 - Sunrise Audio (Simphonio) SW-Dragon II (120Ω; aka "SWD2")
2010 - Sunrise Audio (Simphonio) SW-Dragon (150Ω; 110+/-3dB; aka "SWD")
So the
Shozy BK is a good choice if you prefer a warmer signature and the
Simphonio SWD3+ if you like treble and are not turned off by bright characteristics. The SWD3+ does offer more details and better timbre than either the SWD3 or the SWD2+ which I found to be very similar (believe I liked the lower impedance SWD2+ better than the SWD3). The Simphonios are quite resolving probably perfect for critical listening such as grand dynamic classical pieces.
Price - Value wise the Shozy BK is the better bang for your buck earbud than the Simphonios which I believe really are way overpriced but that is only my opinion and they are good earbuds nonetheless.
