Are you saying the Havi B3 $60 earphones are better than Shure's $400 earphone?
Can not speak regarding SE535s - never heard them, only 530 ages ago, with an inferiour source to boot. What came out of 530 with that source, was in no way even comparable to B3.
What I CAN say is that Havi B3 does not pale in companion of Stax Lambda Pro and AKG K 1000 - there are areas where the big established counterparts are clearly better than the B3 - but at the same time, there are also worse ... Both Stax and K 1000 are yet far more costly than SE535, even without including the respective amplifiers - none of which are normal "headamps" .
Havi B3 ( provided it is fed from a premium source and amplified by a powerful enough amplifier ( it is about as hungry IEM as it gets, considerably more so than majority of full range cans ) ) is capable of extremely lifelike sound, excelling particularly in soundstege. It is better in this regard than most full sized cans, it even hints at the soundstage of the AKG K 1000, which is so outstanding in this regard - still, after all these years, second to none.
Havi B3 Pro 1 ( Old Version ) is an outstanding IEM. It requires careful matching to your ears ( tips that will do for you can be quite a challenge to find ... ), it needs an extremely powerful amplifier for an IEM, it will follow the improvement in the front end to an unheard of level, totally out of proportion to its cost. It does require some EQ in the bass for proper SQ - and its ulimately achievable SPL in the bass is somewhat limited.
That "somewhat limited in the bass" still leaves both the Stax Lambda and K 1000 in the dust. Neither of them is capable of concert level climaxes in symphonic music , particularly in the bass ( timpany, big drum ) - B3 sort/kind of "does it" - at the limit, with slight compression, but without the audibly objectionable protest. While doing it, B3 will never feel going out of composure - the overall soundstage remains solid and unperturbed.
Its greatest asset is freedom from audible resonances - there are no particular spots across the entire range that cause trouble, which, once heard, will bring you on the fence to listen when it will occur again - which is THE prescription for inducing listening fatigue.
That is something totally alien to the B3 sound. It may have not enough bass ( for some music, for some listeners ) - but you can go trough the entire thread and its "parent" thread ( Chinese / Asian Brand Info thread )
and you will not be able to find a single complaint in this direction.
It takes Havi B3 Pro 1 (Old version ) some 300 hours of normal playing ( burn-in, if you prefer ) to develop the proper bass extension and lose grittines in the treble; bass gets OK sooner than treble, if it is still somewhat coarse ( REMEMBER - from a good source/recording, it will mercilessly reveal inferiour recording and/or source ), play it a little longer. If you are not interested how it develops in sound, you can play say a FM tuner at normal listening level for say 12 or so days, with Havi in some drawer not to disturb anyone in the household.
I hope that helps - equating the price with subjective quality does not necessarilly hold true. Please note that IEMs are perhaps the most PRIVATE thing there is - and no one can guarantee that you will perceive the Havi (or any other IEM ) the same as majority on this thread. But due to the above and almost countless other testimonies it does make sense to go yet another mile with B3 ( tips, amplification, recordings ... ) - while it may well end up being the least expensive part of the entire chain, it is most unlikely to be the - weakest link .
