Short answer: the FiiO FT13. It ranks #210 of 481 over-ear headphones by sound quality, rated 3.7/5, at $329.99. The Sivga Audio Phoenix ranks #226, rated 3.6/5, at $309, $20.99 cheaper, which does not close the gap in sound quality.
What the FiiO FT13 does well: Closed back, with bass and sub-bass about 1.5 dB above target and a solid 30 Hz extension, so it isolates well and delivers weighty, warm low end. Watch for: An 8.7 dB dip near 4 kHz pulls back presence, so vocals and guitar attack can sound veiled, and the 6 to 10 kHz treble also runs nearly 3 dB low.
The case for the Sivga Audio Phoenix: Oratory1990’s measurement gives it a preference score of 72 with a fairly even 2.3 dB standard deviation, and its warm tilt with bass about 2 dB above target suits warm and bassy tastes. The catch: Low mids sit nearly 3 dB above target, which can thicken vocals and make dense mixes sound slightly muddy, and a 4.3 dB dip near 3 kHz recesses voices a touch.
Buy the FiiO FT13. It is rated higher for sound quality, and the $20.99 saving on the Sivga Audio Phoenix is not enough to make up the difference.
