These are one of the best IEMs you can get at this price point. Although the IEMs are a little big, they're very comfortable. The sound profile (for the default setting) is excellent. Just don't switch to the other impedance mode. The music loses it's warmth.
Truly exceptional IEM for the price. Highly palatable tuning, fantastic timbre (blindfolded I would’ve guessed a single DD), and surprisingly good imaging capabilities and dynamic contrast.
My expectations were high for the Volume S. I haven’t heard a bad set from Softears (RSV, Twilight, Studio4), and almost all of the initial reviews for Volume S were positive. To my ears, it’s a very well tuned set that easily competes with or betters the competition in the price range. I much preferred the low impedance setting, and that’s tuning used for this review
What I like: Vocals really sound great. There’s enough warmth to give some weight and body to male and female vocals. Detail retrieval is excellent. Stage size is also a cut above sets at this price. It’s a very fun tuning.
My favorite set that I own in the $300 to $400 range is the Hype 4. These sets compliment each other very well. The hype 4 has better treble extension and imaging, but vocals and stage are better on the Volume S. The hype 4 and Volume S differ in low end tuning. The hype 4 has more and tighter bass due to the bass tuck. The Volume S has more midbass, but the low end is still tight with minimal bleed into the mids. Both bass guitar and kick drums sound full with good weight. I have a pretty wide range of music in my library and with the addition of the Volume S my library is fully covered. The Volume S is an easy recommendation.
The unboxing experience for these was excellent. You get a lot of accessories and a premium case. The build and fit are excellent. The sound...these are very balanced sounding in low impedance mode (which is my preferred mode). The high impedance mode can cause the upper mids and treble to become a little too forward for my preferences. In low impedance mode, these sound amazing. The tuning is very agreeable and I think most folks will love these IEMs.
Love the form factor, extremely well designed, doesn’t draw too much power and powers all my IEMs with ease
10/10 would recommend
Can never go wrong with going with MusicTeck. Top quality, top quality.!! in every sense. Merchandise customer service and fast shipping. 
Love the silver flash! Doesn’t lack body in the mids, vocals are pretty decent not too warm not thin sounding. The detail retrieval seems up there with the best dds under $300 while being more musical sounding than my dunu falcon ultra, fiio fd15, Questyle nhb12 and tanchjim origin. I highly recommend pairing them with something like the kiwiears x b-media Terris cable with the usb c, it drives them extremely well and makes for a great edc iem. Also highly recommend trying them with Jvc spiral dots pro epfx-12 for a well balanced listen without sacrificing the treble detail.
