I got the Monk+ today. I feel like I was spoiled by the RX-1. RX-1 has a better refined overall sound. RX-1 does better in sound stage(sounds open), and bass, more definition in the mids and highs sounds more extended.
Monk+ does a good job, but RX-1 trumps it. I say if going cheap Monk+ is good enough, but pay more with RX-1, and you'd get a better experience. I don't think RX-1 is really pricey either given it being an over-achiever.
I think the larger speakers on the RX-1 has benefits to sound stage and the bass at least. So, not all that impressed with the Monk+ after having RX-1 for awhile. RX-1 is seemingly a gem.
I assumed earbuds general sound as open as RX-1, but comparing to the Monk+, RX-1 seems unusually more open sounding than at least Monk+ level.
Didn't hear Monks, but they have been replaced by better sounding value earbuds as far as I can tell by other people's reviews/comparisons.
Monk has a standard MX shell and driver size - 15.4mm, while RX-1 has a slightly smaller driver at 14.3mm. At this ultra low price, Vido has a better sound stage and bass than RX-1, but RX-1 fills the stage better and in a more natural way. Bass is also of slightly greater quality on RX-1. High end extension is better on Vidos but again, quality suffers a bit in comparison to Auglamour.
So, up to this point, these 2 would be comparable in the same price range - having to decide between quantity and quality in many ways, but then you add the sublime mids of the RX-1 and overall build quality, design, accessories, better fit for most people and you suddenly realize that RX-1 is absolutely worth it. Also, I was comparing them to the ultra budget king in many people's eyes and I would even say that RX-1 offers even better value, except that Vidos are better all rounders because of that bass and high end quantity.
RX-1 can really impress sometimes, creating big out of this world sound akin to much more expensive open back full size headphones, and I could never get to this stage of being impressed with Vidos.
