↑↓ = difference vs the ★ model; lighter, longer battery and wider response are shown in green. “—” means the maker does not publish that figure.
FiiO FT3 is FiiO’s over-ear, released in 2022 at $299. The spec sheet lists dynamic、60 mm、350 Ω、105 dB、430 g。Its value is not one dramatic number but where those specs land at this price.
1. Where it sits on the shelf
On this over-ear shelf its price ranks 54th (102 models with a price), and 1th most expensive of the 16 models in the $200–300 band. At 430 g it ranks 90th lightest of the 101 models with weight data. 350 Ω ranks 4th highest of the 62 models that publish impedance. 105 dB ranks 10th lowest of the 68 models that publish sensitivity.
2. What the numbers change in daily use
At 350 Ω and 105 dB sensitivity. A phone alone struggles, so a desktop amp or a decent dongle is effectively required.
The rated frequency response reaches 40 kHz.
3. Fit, isolation and use cases
At 430 g it is on the heavy side for this form factor. No water-resistance rating is published, so sport and rain are out.
4. Head to head with its three closest rivals
The three closest rivals at this price are the HiFiMAN Sundara, AKG K712 PRO and Grado SR325x. HiFiMAN Sundara ($299 (same price))：372 g、94 dB；AKG K712 PRO ($299 (same price))：235 g、62 Ω、105 dB；Grado SR325x ($295 ($4$ more))：345 g、32 Ω、99.8 dB。
5. Weaknesses worth stating
- No water-resistance rating is published: sweaty workouts and rainy commutes are out.
- It needs a front end: 350 Ω with 105 dB is a hard load for a phone.
- Price position: of the 16 models in the $200–300 band, 0 cost more and 10 cost less.
6. What to buy instead at the same price
- The direct rivals are the three models from section 4 (HiFiMAN Sundara、AKG K712 PRO、Grado SR325x) — which to pick depends on the spec you care about.
- Other checkable models in the $200–300 band: HiFiMAN Sundara（$299、94 dB、372 g）、Audeze Maxwell（$299、28 Ω、95 dB、490 g）、Shure AONIC 50 Gen 2（$299、44 Ω、97 dB、334 g）.
7. Who it is for — and who it is not
- Anyone who already owns a desktop amp or a good dongle: its ceiling is the front end.
- Straight out of a phone: 350 Ω with 105 dB is a real struggle.
- Sport or rain: no water-resistance rating is published.
