This and That:
Ample amount of included accessories. I especially love the carrying case (that is softly padded in the lower half but unfortunately lacks any padding in the upper one).
Unique UFO/disk design.
I really like the easy to see red and blue side markers.
Semi-open design with 12 vent holes on the inner half.
The rather short nozzle, angle and location of the vents will lead to a high likelihood of the Titan 1 (, 3 and 5) sounding very different from person to person, depending on if and how much those vents are covered (which will influence the amount of bass as well as to a much lesser degree the middle treble response), depending on one's individual ear geometry. That's also why there are different impressions on the internet about the sound signature/balance (bass quantity) of the Titan in-ears. Therefore I definitely wish that DUNU had solved the venting somewhat differently and re-located the holes (if it were possible).
Very supple cable with good strain relief. I don't like the fabric coating though, as it will (and already does) fray and show signs of wear over time.
Sound:
Low impedance sources, largest included red core silicone tips.
Tonality:
In my ears and with my ear geometry and fit, the Titan 1 sounds mostly v-shaped and bassy (but not bass-heavy, as long as the vents aren't fully blocked).
The lows' emphasis is very even and extends flat down into the sub-bass without any roll-off. Sub-, mid- and upper bass are equally elevated, with a full low fundamental range that decreases to around 700 Hz where the quantity is neutral again.
The midrange appears subjectively recessed and somewhat distant sounding.
Midrange timbre is mostly correct with the upper mids being probably just a hair on the brighter side.
The treble is generally emphasised and bright in the middle and upper highs, with good extension in the super treble past 10 kHz.
As the middle treble around 6 kHz is already clearly emphasised, the Titan 1 will be a hit or miss in-ear in terms of treble, as it does indeed sound somewhat strident and sharp, and lacks a bit or realism as a result. The bass balances this out to some degree, but the brightness and sharpness in the middle treble cannot be denied.
Resolution:
The resolution is on a very good level and definitely among the best for dynamic driver in-ears in the price range of around $100.
Speed, tightness, control, resolution and separation are attributes that describe the Titan 1.
The lows are very tight, fast, clean and feature great control for dynamic driver standards.
The midange is the Titan 1's weakest point when it comes to resolution, but only relatively. Compared to the lows and highs, the amount of midrange details seems to be a little lower (comparable to my Logitech UE900 or Pai Audio MR4, two in-ears whose mids I also perceive as being somewhat less resolving than their lows and highs), nonetheless speech intelligibility is still good.
The treble is detailed and well-differentiated, with clean separation.
Spatial Presentation:
The soundstage is really large, airy and open sounding, with great extension to the sides and just as remarkable spatial depth.
Layering and imaging are precise and clean, with precise instrument separation and placement.
Conclusion:
A really nice in-ear with high technical qualities and a very large, open soundstage. The only thing that it exaggerates is the middle treble around 6 kHz that tends to sharpness and stridency.
