Changelog
Recent updates to the catalog and the site — newest first.
-
JCALLY Space (HiFi Edition) added
Added the JCALLY Space (HiFi Edition) — a single dynamic-driver IEM with verified specs including 32 Ω impedance, 108 dB/Vrms sensitivity, a 20 Hz–40 kHz frequency range, and a detachable silver-plated cable.
-
Binary Acoustics 1900 added
Added the Binary Acoustics 1900 — a hybrid IEM pairing a 10mm dynamic driver and passive radiator with four balanced armatures — with verified specs including price and a detachable silver-plated cable with swappable 3.5mm/4.4mm plugs.
-
12 new earphones added
Added 12 new earphones — including the TRN Whale Shark, DUNU DN242, Hidizs MP145 Pro and the Shanling MG20 — each with verified technical specs.
-
Tolerance band around the target
When a target is selected, the chart now shades a soft ±dB tolerance band around it — the rough range within which a curve tracks the target closely. The band is tighter through the ear-gain region (where the ear is fussiest) and wider in the sub-bass and air. It only shows in the normal overlay, not in the difference views.
-
Rig shown per curve in the chart tooltip
The chart tooltip now shows each curve's measurement rig (711 or 5128) next to its dB reading, so you can tell at a glance which coupler a curve was measured on — not just on the product and hover cards. Curves with an unknown rig show no tag.
-
How To Read: measurement rigs explained
New How To Read section on measurement rigs (couplers): what the IEC 711 and B&K 5128 are, why curves from different rigs aren't directly comparable in the treble, and how Songbird tags each curve's rig, warns on mixed-rig selections, and offers optional rig compensation.
-
Noble Massdrop X and K10 removed; Annihilator re-sourced
Removed two Noble earphones — the Massdrop X and the K10 — because we no longer had a verifiable public measurement for them. The Elysian Acoustic Labs Annihilator (2021) was re-sourced from a different public measurement so its graph stays verifiable.
-
CrinEar removed from the catalog
Removed the CrinEar earphones — the Daybreak, Meta and Reference — from the catalog.
-
Measurement source refresh
Refreshed the source measurements for 14 models — among them the Final Audio A3000 and A4000, Oriolus Trailli, Vision Ears Phonix, Unique Melody MEST Fortune, Artti T10, Forte Ears Macbeth and Mefisto, and the Elysian Gaea — re-pulling each curve from public squig.link sources so every graph stays consistent and verifiable. A small number of entries that no longer had a verifiable public source were removed from the catalog.
-
New brands: Meze, Ice Labs, Binary Acoustics and more
Added 13 earphones with verified specs: Meze's in-ear range (Advar, Alba, 12 Classics V2, 11 Neo), Ice Labs (Prismatica, Spectrumica), Binary Acoustics (the Gizaudio Chopin, DynaQuattro, EP321 MEMS), the Sennheiser IE 100 Pro, Juzear Defiant, Kiwi Ears Astral and Punch Audio Martilo.
