The problem with the Yincrow RW-777 I have is mostly that I can't find much information about it. I only found two reviews in Japanese, one seemed to say it was good but not great, and the other said it had a wide soundstage that didn't compromise the details, which sounds great.
I am also worried about the quality. I bought the Yincrow X6, and while I like the sound when I want something warm with bass splash, I haven't seen such a thin and weak looking cable in a long time, and the pictures of the RW-777 also seems to have weak cables.
At the current price, the Aurvana Air is about 10 USDs more, but I get amazon prime delivery time and return potential if I really hate it, so I am really leaning towards that option.
Since you have it, what are your impressions of it? Does the cable look sturdy and durable? How are the imaging and soundstage? Does it sound natural and coherent?
I can understand you. I bought it blindly together with NiceHCK Graphene and DIY PK2 and got a good package deal since I'm a returning customer.
There are so many new great earbuds around $20-25 that the price range ~$40 to $100 might be skipped over. That will work against something like RW-777.
Have you seen Sennheiser MX980/985 in real life? The cable on RW-777 reminds me a bit of it. A bit on the thinner side but not really weak. Overall the build is good and looks professional. The housing is the same shape as Hifiman ES100 but in metal instead of plastic.
The only thing I cannot understand is why the earbuds are not marked with R and L. They are asymmetrical so that helps (as well as listening to songs you know to decide which side is right and which side is left).
I used RW-777 to work today and I can say that they doesn't really work with thrash and death metal. They are transparent and very clear sounding but the sound is a bit too thin. With other genres with mainly acoustic instruments, they can work great.
I often use this instrumental Allan Holdsworth track (either the Road Games (1984) version, or the one I prefer off Wardenclyffe Tower (1992)) to see how earbuds can handle imaging and soundstage. There's a ton of percussion used and reverb and delay that adds to the depth.
RW-777 handles it without any problem. Every little hit on the percussion is well defined and has got a sort of "physical" place in the soundstage. You can easily pinpoint every little sound.The soundstage is deep and wide and out of your head, perhaps because there is no mid bass or mid emphasis? It's probably the earbud I own with the third best soundstage (after Cypherus CAX Red Dragon and ABnormal Diomnes Lv2). Considering that Red Dragon, by far the best earbuds or even headphones I've heard, are custom made and cost over $700 (I got my pair for a little over $600 used) and Diomnes Lv2 used to cost $180 excluding shipping before they were discontinued, that's a pretty good grade to RW-777.
ClieOS wrote this about RW-777: "The RW-777 on the other hand has more of a mature sound - warm and smooth with a pretty good mid-range."
I find it to be smooth and detailed but not that warm. On the other hand it's not bright at all. I do find it to be slightly lean or thin sounding compared to some other earbuds around the same price. That's why I consider it to be more about clarity and soundstage.
Anyway, Creative Aurvana Air might fit your description quite well. There aren't many earbuds with that sort of AKG K70x type of sound...
So you should go for Aurvana Air. At least for now. Until you get an itch to try something new...
