FlipEars Arion Impression

Driver Config: Quad-brid design with DD/BCD/3BA/Electret

Sound Signature: Balanced, W-shaped.

Tonality: Natural-revealing

Highlights: Bigger shell design with some extra weight, average-size nozzle, a beautifully handcrafted faceplate by a master jeweler that looks like artwork, and a custom Eletech premium cable. Very dynamic W-shaped sound signature with a deep, bouncy bass, layered, micro-detailed mids, and crisp, extended treble. Big holographic soundstage expansion. Easy to drive from any portable source, including DAC/amp dongles.

Suited Genres: Could easily be considered an all-rounder to work with any EDM, pop, rock, and J-pop/K-pop vocal tracks.

Impressions:

This latest flagship from FlipEars takes the Arsenal collection release to the next level, offering well-executed W-shaped balanced dynamic tuning that benefits from a bigger bore opening eartips. The 10mm carbon diaphragm DD is complemented with an EarQuake Bone Conductor driver to add weight and rumble with multi-layered dimension, giving it a more bouncy, fuller presence. The mids are cleanly layered and well separated, slightly laid back with restrained body, delivering natural detail retrieval down to the micro level without tipping into analytical territory. The treble is crisp and airy with good extensions, revealing plenty of detail without ever sounding harsh. The tuning is on the revealing side but remains a solid all-rounder, pairing clean, non-fatiguing micro-detail with a full, powerful bass response that stays well controlled.

Giant Killer

This set is incredible. The bass is some of deepest, most textured I have ever heard from an IEM. Combined with vast staging and excellent layering and imaging, it punches way above its price class, yet it's still balanced and warm enough to listen to all day. It's quickly become my go-to travel set because it just transports me (and that bass slays no matter the ambient noise). I think other IEM makers need to take notice of what can be done for sub-$2K

It’s Not Snake Oil

When You Match These IEM’s With The Hiby R4 Or Hiby R6 iii Or Hiby R8 You Have To Set Your PEQ And MSEB And Then EQ To Your Taste 😇 You Will Find That You Are Touching Grass. When You Go Higher And You Can !!!!!!! Please Know That The Diminishing Return Is Real And You Keep Finding More Of The Same With The Same Features But The Love ❤️ For These Will Help You Relax 😌 And Enjoy The Pleasure Of Listening To Jazz Pop Hip Hop R&B And Gospel. The Pure Sound The Artist Meant For You To Hear 👂 Please 🙏 Enjoy 😊 The Nirvana You Have Discovered And Thats The Pilgrims.

UM Maeven II

The most well balanced IEMs I've ever tried. Satisfying tight bass, sparkling treble, crystal clear soud. Very very good!

How?

I don't understand how you can get totl pwaudio shielding for this price.
The black background is immediately perceptible, palpable, and delightful.
I own cables at and above it's price and this stands out. It pairs with the UM mest jet black very well.
The imaging feels a cut above, sounds come from the abyss, and still have texture. I was worried it would overly smooth the highs but they still have defined edges and articulation.
Bass has depth & weight, the mids aren't shoved in your face. The biggest surprise is how detailed it is, I still get the micro detail I love, now set against the blackest background I've experienced.
*I was also worried about the ergonomics and yes it is a bit stiff due to the shielding, but I could go for a walk and didn't notice it at all, it's still soft, light, and doesn't move your iems while you're moving like some cables do.
Best $300 I've spent in the hobby so far, getting to hear proper shielding at this price is an insane value imo.

Really good case for an even better portable DAC Amp A100

Leather case fits perfectly, good quality
