Meze 105 AER vs Sivga Phoenix

Meze 105 AER

Meze's lightest open-back at a rated 336 g, the 105 AER pairs ABS-PC earcups and a metal frame with a self-adjusting suspension headband and breathable velour pads, and it is built to come apart so worn parts can be replaced. Comfort and drivability are the traits reviewers keep returning to: rated at 42 ohms and 112 dB, it reaches loud, clean levels from a MacBook headphone jack or a small dongle, while dynamics, imaging and clarity firm up when it is given a better source. The tuning reads warm-leaning and forgiving, and the midrange is picked out as the high point: a clean bass-to-mid handoff climbing to a 3 kHz hump, natural timbre on acoustic instruments, and vocals that are intimate and full without shouting. Bass carries a light emphasis weighted toward midbass punch and holds structure rather than bloating, though how much sub-bass rumble is really there is disputed. Treble is the contested region: it is described as smooth and rolled off with a recessed 6 kHz that softens note attack and costs bite, and also as sparkly, crisp and a favorite quality. Staging divides the same way, called wide with good left-to-right spread on one hand and surprisingly narrow in stereo width on the other, while imaging and layering are treated as a strength either way. Against the 109 Pro at twice the money it is warmer, smoother and clearly behind on resolution, extension and sparkle. The single-ended stock cable is the recurring packaging complaint.

Sivga Phoenix

The Sivga Phoenix is a 50mm dynamic open back with CNC-machined zebrawood cups, stainless steel grilles and a listed 296g weight, and the physical product is the least contested part of it: premium materials with no visible flaws, a light clamping force, and a rated 32 ohm, 103 dB load that a phone or dongle drives without help. Tuning is where opinion divides. Listening-based reviews hear a warm, full-bodied signature: textured bass with sub-bass reach unusual for an open design, a lush and expressive midrange, and a treble that sits on the safe side of bright without fatigue. A measurement-based review reached the opposite conclusion, finding the response close to target only between roughly 100 and 500 Hz, with the emphasis concentrated at 200-300 Hz and a shortfall above, which it heard as dull and would not recommend in stock form. That same review reported a dramatic gain in tonal balance and spatial imaging once parametric EQ was applied. Soundstage width is also contested, called fairly modest and narrower than rival open backs in some listening and notably more expansive than a Sennheiser HD 600 in other listening. So are the stock pads, thin enough that one listener felt ears pressing against the driver covers after about an hour, while others logged multi-hour sessions without fatigue. Detail retrieval is a stated limitation: respectable, but described as neither the cleanest nor the most detailed at the price, with micro details sometimes going unnoticed.
