I own 2 of these pieces for the soprano. One is the s27 and the other is the s35 jazz. Although they are for soprano, I am 100% sure that they share the same chamber design as the ones for alto, tenor, etc.
There is no difference of chamber designs between the two mouthpieces. If you take a look at the chambers of both mouthpieces, they are exactly the same. The only difference is with the tip openings. The s35 has a much bigger tip opening than the s27, which makes it much louder. However, even though the s35 is louder, it can still blend rather well with many types of music. I've used mine for classical to smooth jazz to even loud, pop and jazz music!
One more thing. If you decide to get a v5, make sure you pair it with a proper Vandoren reed setup. Although any reed will work, I found that these pieces work best with Vandoren reeds. The Vandoren website even provides recommendations of which reed and strength to use on their website (
