"Prestige is also unchallenged at every frequency and capacity. With its ten drivers (assigned to bass, midrange, mid/high, high and super-high frequencies), Prestige delivers exceptional sound quality with a wonderful coherence across the frequency spectrum. Despite its driver complement, Prestige is no larger than any conventional custom-fit product in the Noble Audio range. Prestige comes with a detachable two-pin cable and further supplied accessories include the Storm Box (crush-proof carrying case), two Noble Audio bands or amp bands, a cleaning tool, a Noble cable plus an ownership card. It carries a two-year limited warranty."

Constructions materials span the gamut:
"Exotic wood: Hand-picked and graded for quality, the exotic woods include a curated selection spanning the United States, tropical Africa and South East Asia.
Wizard's wood: Exotic woods combined with the colour(s) to create palpable textures and finishes.
Dyed wood: Neutral-coloured woods dyed either a single colour or a progression, enhancing figure and character.
Honeycomb: Genuine honeycomb cast in various colours creating an organic, naturally occurring and geometric landscape.
The Matrix: Similar to Honeycomb in terms of pattern, The Matrix consists of aerospace-grade aluminium webbing that is rigid in structure but profiles nicely with the contours of the ear
Carbon Glass: Pieces of stiff 12mm carbon fibre infused with various colours and metallic finishes producing a glass-like appearance."

I also asked Brannan if K10 included innovations like Lear’s LCM BD4.2: "We don't claim any innovations when marketing our products, however with the K10 we wanted to create something to listen to music with, not necessarily make music with. Most other in-ear monitor companies are very artist/musician driven. Our approach to design is different as we don't directly cater to this group."

And my last question was about technical details of the Prestige:

• 10 precision tuned balanced armature drivers
• Four-way passive crossover design
• Two balanced armature drivers for low-frequency reproduction
• Two balanced armature drivers for medium frequency reproduction
• Two balanced armature drivers for medium/high-frequency reproduction

• Two balanced armature drivers for high-frequency reproduction
• Two balanced armature drivers for super high-frequency reproduction
• Noise isolation: -26dB
• Impedance:  35Ω
• Socket type: Non-recessed two-pin Westone style
• Warranty: 2 years

Before my sound impressions, here is the $64’000 question: What do we seek from portable audio? Fun? Clarity? Analytical sound, maybe neutrality? V-shaped, mid-centric or bass dominant? Since my album collection centres on classical and jazz, my cup of tea would float neutrality and analysis. Was I sure about that? If so, why wasn't I too happy with my Hidition NT6, one of the most neutral and analytical custom IEM to market so far? Why have I already called my experience with the K10 as destroying all of my prejudices about portable audio? The answer hides in the word portable.
