This and That:
Slim plastic package. Comes with three pairs of differently sized silicone tips and a storage pouch (a case would've been nicer, but a pouch is better than nothing and still okay in this price range).
Quite small shells, however I wouldn't call them "tiny" yet (they're "almost tiny" though).
Nice design; I like the carbon fibre and dark grey aluminium.
No build quality issues; seems very decent.
Soft cable but doesn't appear very durable. Strain relief should be better.
Sound:
Quite strong tonal difference depending on insertion depth. Dark highs when inserted really deeply (doesn't appear natural to me, as then the shells are completely inside my ear canals and only the cable protrudes), somewhat dark highs with "normal" insertion depth (which is how I wear my Carbo Tenore).
I'm using my Carbo Tenore with the largest included silicone tips as well as mostly with low impedance sources.
Tonality:
V-shaped with really nicely implemented bass boost.
Fundamental range and upper bass with only mild emphasis; strongest quantity in the sub-bass, so really a mainly sub-bass-focused bass emphasis with around 12 dB of elevation in the very lows. The sub-bass implementation reminds me of that of my Shure SE846, but the Carbo Tenore's is even a bit stronger in the sub-bass.
Nothing bloated, just nicely done, pure fun sub-bass elevation. Nice.
Mostly correct sounding midrange timbre but subjectively a bit recessed sounding in the mix.
Slight lift between 2.4 and 3 kHz.
Therefore mostly realistic voices, with only very dark and very bright ones being somewhat elevated (hence the subjectively recessed sounding mids in the mix).
Lift around 6.8 and 7.8 kHz, adds some brightness.
Resolution:
Decent for the price but not the great "killer" it's often said to be. My Fostex TE-02, Havi B3 Pro I and TTPod T1 as well as the Fidue A65 outperform my Zero Audio Carbo Tenore. It's appeal is really mainly its tastefully implemented bass elevation, and that it's otherwise rather decently tuned as well.
The upper middle/lower upper treble elevation can be a bit unpleasant (bit sharp) at times, as the in-ear only resolves averagely, just like one would expect in this price range.
Just like the treble differentiation, I wouldn't mind if the lower bass were a bit more precise and differentiated, nonetheless tightness and precision are still quite decent for a dynamic driver in-ear, although the Carbo Tenore falls short of the bass performance (tightness and speed) of my single-BA Sony XBA-C10 or MEElectronics A151p, but that was to be expected anyway. Nonetheless it isn't one of those slow and mushy sounding dynamic driver in-ears (unlike my SoundMAGIC E10).
So yeah, decent/average resolution for a dynamic driver in-ear in this price range. Nothing unexpected, but not as much value for the money as my aforementioned Fostex, Havi and TTPod as well as the Fidue, all of which are tuned quite differently though (more neutral or balanced respectively a different kind of fun tuning).
Soundstage:
Rather narrow to my ears and quite comparable to that of my Logitech/Ultimate Ears UE200. Not flat sounding though and has got some spatial depth, although it's not a large or open sounding stage due to the rather limited width.
Decent instrument separation and imaging, but that collapses somewhat with more complex tracks (the Fidue A65's soundstage copes audibly better with complex and fast tracks, despite having a small soundstage).
Conclusion:
Decent sounding in-ear. Nothing (except for the tastefully implemented bass elevation) stands really out, but it is worth its money.
