@ballog thanks very much bro, and i will be sure to compare to the Shozy BK, as i am sure i will end up buying it for myself....

Superb man! One the best earbud reviews (if not the best). Very tempted to buy one - just wished it came in another color than the red. I'm waiting for the Shozy BK to show itself on Aliexpress before deciding though. Thanks again for the effort bro.

@vapman if think my taste in earbud sound signature meets yours. I too listen at very moderate volume but for example even if i'm listening to a jazz album I like to hear the bass note and the kick of the bass drum. Even listening to a quite subdued band like Dirty Three I like hearing the plucking of the bass guitar - it makes the music more lifelike. My current favorite setup is the RX1 with Viper4android (Viper Bass enabled) on my phone - so I get the clarity along with a quite good sub-bass.

How many burn-in hours did the earbuds logged for this review audition?

@purplesun Between 180 and 200 at the time of review however no notable changes detected after ~60 hours.

Knowing that we have the same taste, this is another bud I have to try. Great review!
god, the struggle: Shozy BK, Hi-Z 650, K's 500, Rose Masya, VX Pro or feeling lucky with this one: https://www.aliexpress.com/item/European-high-impedance-headphones-guild-400-flat-head-headset/32666108405.html
 
hmmm

great review Vapman! thanks for your passionate interest in earbuds and attention
to the musicality of the HiZ 650.  I know you are also a performing musician and
you know what that sounds like, so these must be something really special! Bravo!

Very nice review my friend. Thanks!

VAPMAN, kudos on all your reviews out there. What is your artist name BTW? Just curious how serious an artist takes his taste, compared to the likes of Lady Gaga who just wear Heartbeats and that's it.

I'm eyeing your HiZ-650 take, but the price is a bit steep for me atm.

Here's my quick review and comparison of what I have and so far, the HiZ 32 ohms are my fav.

Just purchased HiZ-650. I currently have FiiO E11 as my potable amp. Do you think it would be good enough to drive these? If not what would be your recommended amp? I play my tunes on iPod 7th generation.

CMOYBB portable amp with 2x9V batteries works very well with HiZ-650. Before I ordered CMOYBB I asked them to reconfigure the amp for the HiZ-650 and they gladly did that for me (by adding 2x9V batteries and doing something else). The sound is super good now with ether my iPod 7 Classic or ASUS ROG. Also when I listen to Hemi-Sync products I don't even need the amp.  Amp is only necessary for rock, trance, pop and music in general.

Khan if you believe your own comparison then it should be no question I taste my taste very, very seriously.
