I think worth it or not depends on what you value more liao. Just purely sound wise, I still prefer the haylou gt1 plus and that is like S$2X only. S2 still sounds good, and is probably more "fun" sounding with more bass and treble, it can get much louder, and some might prefer those things more. Most regular users probably aren't as particular or might not even know the type of sound signature they like, but minor things like the slight sibilance and the thinner mids takes away from the experience a tiny bit for me. For me the value is in the other stuff. Like USB-C charging, nice case, nice design. But i wouldn't pay more than 29USD for sure. hahaha
But ah, stuff like the truedot and gt1 plus are probably anomalies in the market. A lot of more mainstream TWS in the market are probably more expensive and might not even sound as good as the S2. So to a lot of ppl out there, it is still going to be really worth it, not to mention it's from a fairly reputable Chi-Fi brand.
I would have got GT1+ if it has volume control. I would have really appreciate the more complete functions. I wont say the Awei T10C i am using is perfect because the sound is kinda eeee, but functions wise meets all i need. No master slave (QC tws+) issue, have volume control, avg batt life only, good thing is price is ok. So that is my beater for walking out, while Sabbat E12 ultra is when i need to take long journeys on public tpt which of course now #stayhome no need de...
Maybe they will silently update the model in the future again and change the controls. haha.
