I eventually received my Openhearts and at £23 I am pleasantly surprised. Mildly V-shaped, they deliver good sound and in my view they surpass, the Blon BL03.
Starting with my reservations. The mid bass appears to be unruly, rather like my initial impressions of the ISN H40 (in the end the H40 settled in my view). Also, like the H40, these are very easy to drive (as a consequence they come across as loud) the effect is that listening at higher volume may sometimes sound congested on a "busy" track but on most tracks, these sound very good. I have had them for some 48 hours or so still early days.
What they do well is deliver good sub-bass, the treble is very good ( not quite Starsea levels, but many do not get to Starsea levels of treble extension) and being V-shaped, the mids are not prominent but they will give you some glorious vocals, piano, guitar and saxophone solos well beyond the money you spend.
The instrument separation is very good, with a good deal of detail so that you can focus on one instrument without losing it on a congested track (bearing in mind the current higher volume limitations, which might improve with time). The timbral accuracy, as you would expect on a Dynamic Driver, hhhmmm, just so real...Great, we are talking about a £23 single DD and it does not disappoint....rather, it is impressive in my view. Maybe the earphones to take the place of the BL03. Let's see how the Dynamic Driver settles with time.
Questyle builds really stylish gear, but their poor aftersales support and communication, even relative to other Chinese companies, has always given me pause. It's almost like if something goes wrong, you're pretty much on your own.
