Looking at your requirements, I actually think the Olina with filter mods (either tanya filter or double stacking the Olina filters) may be possibly an option to consider.

The sub-bass and mid-bass were also significantly increased with a meatier rumble and a more physical mid-bass punch. As mentioned previously, there is a red band over the right cable terminal so that one can use this as a marker for the right shell housing.The Moondrop Aria is a 10mm LCP diaphragm and CCAW voice coil DD with a brass-plated inner cavity and a neodymium N52 magnetic circuit inside.

As always, some will prefer their music delivered with more character, favoring more prominent mids, or brighter highs, and there are plenty of options on the market to meet every need. I found the supplied silicone tips to be more comfortable than average among the IEMs I’ve tried, and it was easy to get a good fit with these. Overall, the bass on the Aria is quite pleasing and not overpowering to the point that it drowns or muffles the vocals. Replacement parts are easy to track down, plus it uses more sturdy MMCX connectors and sounds great.However, overall, I would prefer the cable on the Aria as it came with a standard chin slider which is important for me personally when using IEMs on the go. as for now I love the vocal/mid on the chu, I just find that Chu is just a ‘lil bit lacking on mid bass for my preference. The only problem I encountered with them is that the ear tips that came with the earphones were uncomfortable for me.

That’s great if you happen to lose one, or need to swap them out because all ear tips get old and nasty over time. There is not a huge amount of detail on the supplied cable, but we do know it uses an SPC wire rather than copper, 1. I really like the sound character of moondrop is there a model with a better build quality with similar sound?The Aria's composite sound chamber, tuning holes, and acoustic dampers ensure precise frequency response and superb sonic performance.

Where the Aria differs from the Starfield is in the composition of the diaphragm which is a 10mm LCP (Liquid Crystal Polymer) liquid crystal diaphragm which is a material used by the likes of Sony in some of their headphones for an enhanced HF response. The Olina are more technical and aggressive and are better for critical listening compared to the more subdued Snow Edition. Not sure if you have gotten it, but you can get an adapter, or make one using microtape and taping around the nozzle, to take on different ear-tips.

Moondrop has created quite successful earphones in the past and it seems bent on making its designs cheaper and cheaper.
