Just received a review unit of the DUNU Titan S. Here are some quick impressions:
Accessories wise, really quite excellent.
Included are:
1) IEMs themselves
2) Cable - High-Purity, Mixed Strand Monocrystalline Copper & Silver-Plated Copper 0.78 mm 2 pin plug - it is sturdy enough, but is on the thinner side and has slight microphonics
3) 3 variants of silicone tips (S/M/L)
4) Shirt clip - this can minimize microphonics if used
5) Leatherette zip pouch - quite elegant with inner lined velvet material
Build-wise, the IEMs themselves have a steampunk metal finish, and they look quite bada** if I'd say so. They are very comfortable with no weird edges. Nozzles are long and should give some extension for those with big ears. However, not sure if those with smaller ears might find these IEMs sticking out of the ears a lot.
Isolation is average, as per a vented single DD set. They are easy to
drive from lower powered sources, but as per most single DD, amping scales dynamics and soundstage/micro-details.
Now on to sound, the most relevant portion!
The Titan S are a
neutral/neutral bright IEM.
Graph of Titan S via IEC711 compliant coupler. 8/9 kHz is a coupler artefact peak.
Bass on the Titan S is just a tinge north of neutral, and this set is mid-bass centric. There is not much sub-bass rumble, so this is not an IEM for bassheads. What the Titan S cede in bass quantity, they ace in quality, with the bass being tight, fast and accurate. Texturing is above average, with no mid-bass bleed.
The lower
midrange is neutral, and may sound a bit thin in note weight due to the lack of mid-bass bleed. Upper mids are forward without being shouty, with just a 10 dB pinna gain here. They are not fatiguing and the midrange is very transparent and clear, with female vocals predominant over male vocals.
Treble is quite well extended but not fatiguing. Clarity and micro-details are there without being overly pushed, with cymbals/high hats not being splashy. Sibilance is minimal to mild.
Timbre is authentic for vocals and acoustic instruments, though note weight is on the thinner side. In terms of
technical performance, imaging, instrument separation, clarity and micro-details are excellent for a single DD. Soundstage is wider than deep/tall, and would just be on the average side all things considered.
I know this year is the year of the LCP diaphragm battle, with the Tin T3 Plus and Moondrop Aria 2021 being the main competitors for the Titan S at this price bracket.
I haven't done in depth A/B testing, but the Titan S is definitely more analytical and technical than the Aria, with more treble extension and sparkle than the Aria. The Titan S definitely has better bass texturing and technical performance than the Tin T3 Plus, which is quite one noted in the bass with an undefined textureless bass. All 3 sets have good timbre as per their single DD roots, but the Titan S will be the most analytical and technical of them all.
Even compared to the highly lauded HZSound Heart Mirror, another neutral bright budget single DD, the Titan S have a better soundstage and timbre and less peaks in the upper mids/treble. Would have to do some detailed A/B testing to compare the technical performance of these 2 sets, but the Heart Mirror is harder to drive.
There aren't many neutral bright/neutral IEMs at the budget segment, most are tuned V shaped or harmanish to suit consumer preferences. I do think the Titan S is very unique in this aspect, tonality is excellent for a neutral set, with good timbre and technicalities. The Titan S has few weaknesses in the tuning, perhaps only bassheads might stay away. I can recommend this set out of the box for someone looking for a well tuned neutral signature.
Will do burn in and do detailed comparisons with the other single DD contenders and report back!
