TRN ST7.
5 BA + 2 DD.
$25.00
Initial thoughts :
Played through unamped Sony A17 (haven't listened to it thru any other Sony DAP, but that's coming up)
unamped DX170
unamped Sansa Fuze
unamped Cowon J
Nothing stock used (pure copper cable from Z300 + OG Spiral dots)
V shaped. Not exactly mild, but not severe, like those old KZ or the Shangs or RE800. Soundstage is WIDE and has nice depth. Not tall though. Trio has more height and width. Where these are SPECIAL for the price is in the transparency, spatial information as o0genesis mentioned, and black background. The background is very silent, has really good spatiality, and transparency between instruments. I'd say it's on par with the Trio and the Aures in that aspect, which is why I love those two so much. Treble extension and air is about on par with Trio, so I wouldn't say it's it's strong suit. I'd say it's good (3/5), but the resolution from those BA's is exceptional for the price. It exceeds the Trio, Z300, Lings, NX7's, and VS3 in resolution across the board. Instrument separation and imaging is above average for the price as well and superior to the EW200, and maybe equal in resolution to the EW200, but lacking the treble grain inherent in the Simgot budget. Treble is smooth and controlled, despite the BA's in the nozzle. Treble doesn't extend out like the Simgots though, and is shorter in extension, with blunted shimmer, but making up for that with nice timbre and resolution. This doesn't sound to me like BA timbre, which is something I was expecting.
With the copper cable and the spiral dot tips, the mids are a touch recessed, but male and female voices have thickness and are resolving. There's a hint of mid bass warmth, but not really any bleed, and if there is, it allows for some warmth and heft, which is lacking in the Trio, EW200, and NX7.
The bass is still too early to really judge, as I believe in burning in DD's, but early on, they are ok. There's punch and speed. I'm hearing a lack of true resolution down low, but there's some nice sub bass slam. Gives me a feeling similar to the Trio bass, but not with that incredible resolving power that the Simgot bass has on the EW200, EA500LM and the EA1000, but with burn in, I expect there to be some improvements in that area, so I'll reserve judgement for later. So far though? OOTB? For $25.00, TRN has delivered a hybrid that I already enjoy equally to the Shangs, the NX7, the N5005, with some special sauce that exceeds those much more expensive counterparts.
So far, these things sounds really great on warm DAPS (Sony/DX170), but sound more balanced and clear on the brighter DAPS (Cowon J/Sansa).
Comfort? EXCELLENT. Light acrylic shells with really long nozzles makes for a snug firm fit. Bless TRN for providing really long nozzles, unlike the OD200 or those infernal Kiwi Ears.
