AKG K612 vs Sivga Luan

Short answer: the AKG K612. It ranks #73 of 216 over-ear headphones by sound quality, rated 4.0/5, at $279; the Sivga Luan ranks #81, rated 3.9/5, and costs $299, which makes this an easy call rather than a real tradeoff.

What the AKG K612 does well: A preference score of 81 in oratory1990’s measurement puts the K612 close to the response most listeners prefer, and a deviation of only about 2 dB around target means few bands stand out. Watch for: Sub-bass falls 6 dB below target by 34 Hz, so the deepest rumble in electronic and film soundtracks is thin.

Why pick the Sivga Luan: The open back tuning leans warm, with bass from 60 to 200 Hz about 3 dB above target and the lows and mids around 1.5 dB above, which gives music body and weight that suits rock, pop and hip hop. The catch: A 5 dB peak near 2.8 kHz can make vocals and guitars sound forward or slightly shouty at higher volume, and a 5.8 dB dip near 9.3 kHz takes the edge off cymbals while the top octave runs 6 dB above target.

Buy the AKG K612. It is rated higher for sound quality than the Sivga Luan and costs less, so only choose the other one for a particular feature it does better.

AKG K612: $279.00 B&H Photo Video eBay

Pros: A preference score of 81 in oratory1990’s measurement puts the K612 close to the response most listeners prefer, and a deviation of only about 2 dB around target means few bands stand out. Bass from 60 to 200 Hz sits within 1 dB of target and the mids are nearly flat, so voices and instruments keep a natural balance. Neutral and bright listeners are the best match, and at 235 g it is a light open-back design.

Cons: Sub-bass falls 6 dB below target by 34 Hz, so the deepest rumble in electronic and film soundtracks is thin. A 5.2 dB dip near 9.4 kHz dulls cymbal shimmer slightly, while a 4.2 dB peak near 5.9 kHz can make some recordings edgy. At 120 ohms and 101 dB/V it needs more voltage than a phone comfortably supplies, and the open back leaks sound and offers no isolation.

Sivga Luan: $299.00 Amazon eBay

Pros: The open back tuning leans warm, with bass from 60 to 200 Hz about 3 dB above target and the lows and mids around 1.5 dB above, which gives music body and weight that suits rock, pop and hip hop. A deviation of 2.0 dB is among the smoothest in this group, and the preference score is 80. At 38 ohms and 100 dB sensitivity a phone or dongle can drive it, and it weighs 354 g.

Cons: A 5 dB peak near 2.8 kHz can make vocals and guitars sound forward or slightly shouty at higher volume, and a 5.8 dB dip near 9.3 kHz takes the edge off cymbals while the top octave runs 6 dB above target. Listeners who want a neutral balance will find the bass and low mids heavy. The open back leaks sound and has no isolation, and there is no built in microphone.
