Foreword: Another Chinese IEM, the Mini2 is Rose's small form factor, dual driver offering. Frequency Response The Mini2 sounds warm and mid-centric. It doesn't sound as rolled off as presented by the small-volume coupler, but certainly doesn't have the same bite in the cymbals that the IEC raws would lead me to believe. The truth is probably somewhere in-between. Impulse Yikes. Messy impulse. Not sure what this metric explains. Possibly the Mini2 softer notes and dulled transients on subjective listening? CSD Sharp ringing probably an artifact based on its correspondence with the resonant point. THD Another yikes for me, dawg. BA timbre coming in strong with the Mini2. Crispy, plasticky texture despite its warm and rolled-off nature. Impedance Reactivity Surprisingly impedance resistant. Source matching should be a breeze on this. Additional notes: You know, for $100 I can't really fault this too much. Then again, I haven't heard the EDC3. The Mini2 has its purposes; it's essentially a sleeping IEM with a non-fatiguing signature. Definitely not going to fight against similar priced IEMs in technical ability. It does sound somewhat agreeable, I think most people wouldn't outright hate its signature.
