Description / What These Specs Mean
-
Driver size & impedance: The 40mm drivers are a common size for over-ear headphones and provide a decent range of sound. The 32Ω impedance means they’re reasonably easy to drive (i.e., they can work fine with smartphones, tablets, laptops without needing a powerful headphone amp).
-
Frequency response 20 Hz-20kHz: That covers the full “typical” human hearing range, so you should hear bass, mids, highs — though how well each is represented depends on tuning.
-
THD <3%: Indicates distortion is low (at least on specification), so the sound should stay relatively clean under normal listening levels.
-
SPL ~99.6 dB: This gives one measure of loudness potential; it’s reasonably loud for personal use.
-
Connectivity (Bluetooth 5.0 + wired): Bluetooth 5.0 gives reliable wireless connection and decent range/stability. The addition of a wired AUX option means you have fallback when battery is drained or wireless isn’t desired.
-
ANC (4-mic): Active Noise Cancellation is a major feature here. Four microphones indicate a more robust ANC implementation (versus simple two-mic systems). This means better reduction of ambient noise (though still dependent on fit, environment).
-
Battery life + quick charge: Up to ~22 hours with ANC is solid for mid-range over-ear headphones. Quick charge (10 min → ~3 h playback) is a very useful feature if you forget to charge.
-
Weight & foldable design: 228g is lightweight for full over-ear headphones with ANC, so comfort for longer sessions is reasonable. Foldable/collapsible means easier to carry/travel with.
-
Tile tracking: A nice “bonus” feature — if you lose your headphones, you can use the Tile app (~– though you’d want to check region-support) to locate them. Adds value.
-
Sound tuning: Reviews note that the sound profile is bass-heavy (strong low end) and somewhat bright in treble; mid-range might be less emphasized. That means if you like a “V-shaped” sound signature (boosted bass + treble) you may enjoy them; if you prefer very neutral/flat/true-to-recording sound, you might want to consider your preferences.
-
Fit, comfort & portability: Reviewers mention good comfort for many users, but ear-pad interior may feel a bit small for very large ears, and the carrying pouch is basic (not a hard case) so care in transport is advisable.
-
Limitations: Some key things to note: they don’t support high-end Bluetooth codecs like aptX or LDAC (which is common at this price point) so for best audio fidelity you may prefer wired. Also ANC performance is decent but not top-tier compared to high-end (e.g., premium models) — review says they do OK but struggle with deep rumble (e.g., engine/bass noise) compared to top ANC models.
