CONCLUSION

   Emptying and re-organizing my 3 storage areas twice since last year (and once in 2021) ended up complicating things quite a bit for me and so the ov21 is yet another one of those products that ended up in the wrong pile afterwards (two storage areas are for products from finished reviews and the third one for products which have yet to be reviewed). This basically means that the ov21 review should had been up many months ago and so thinksound is yet another company i need to apologise to for this mix-up (hopefully they won't hold this against me). With that out of the way the ov21 pretty much scored very high in all my tests, not only when used with both the M15 and M11S music players by FiiO but also when plugged with my smartphones and even the Creative SoundBlaster AE-9. Starting with bass levels this may not be a model aimed at consumers who want lots of it but it does a good overall job regardless of what genre you throw at it (mostly heavy metal and classic music in my case). Detail in mids is also very good, yes, the ov21 may sound somewhat neutral at times but overall i really didn't have an issue again no matter what genre i listened to. Moving to highs detail here was slightly less than what i was expecting at first but unlike mids and bass this time over performance largely depends on what genre you're listening to and so if you're listening to tracks which are not bass rich then highs actually sound very good. In general, i must have listened to at least 200 audio tracks from the 80's and the 90's with the both the M15 and the M11S (uncompressed FLAC/MQA) and my overall rating for the ov21 is very good. As for comfort levels thanks to its memory foam padded earpads the ov21 is actually very comfortable even after 2-3 hours of use (because of their passive noise isolation however sometimes they do tend to get hot).

   Much like with most other products in the electronics market price is what defines things in the end and with a price tag set at USD384.95 inside the USA (thinksound.com) and at 451.85Euros inside the EU (Amazon.de) the ov21 is certainly aimed at audiophiles who are always willing to spend more compared to regular consumers. That being said however even though thinksound has made some impressive models over the years the ov21 is certain to seem as too expensive for some people and honestly that can't be helped (thinksound is not extremely popular after all). Having used and reviewed more than 300 headsets, headphones and earphones over the years i can honestly say that the on21 will not disappoint audiophiles looking for new headphones upwards to USD500/500Euros and for that it certainly deserves the Golden Award.
