FiiO FT5 is FiiO’s over-ear, released in 2022 at $499. The spec sheet lists planar-magnetic、90 mm、36 Ω、100 dB、459 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 29th (102 models with a price), and 3th most expensive of the 27 models in the $300–500 band. At 459 g it ranks 95th lightest of the 101 models with weight data. 36 Ω ranks 33th highest of the 62 models that publish impedance. 100 dB ranks 27th lowest of the 68 models that publish sensitivity.
2. What the numbers change in daily use
At 36 Ω and 100 dB sensitivity. Ordinary gear can drive it; no dedicated amp is required.
The rated frequency response reaches 40 kHz.
3. Fit, isolation and use cases
At 459 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 Sony MDR-MV1, Sennheiser HD 660S2 and HiFiMAN Ananda Nano. Sony MDR-MV1 ($499 (same price))：223 g、24 Ω、100 dB；Sennheiser HD 660S2 ($499 (same price))：260 g、300 Ω、104 dB；HiFiMAN Ananda Nano ($499 (same price))：419 g、93 dB。
5. Weaknesses worth stating
- No water-resistance rating is published: sweaty workouts and rainy commutes are out.
- Price position: of the 27 models in the $300–500 band, 0 cost more and 21 cost less.
6. What to buy instead at the same price
- The direct rivals are the three models from section 4 (Sony MDR-MV1、Sennheiser HD 660S2、HiFiMAN Ananda Nano) — which to pick depends on the spec you care about.
- Other checkable models in the $300–500 band: Sony MDR-MV1（$499、24 Ω、100 dB、223 g）、Sennheiser HD 660S2（$499、300 Ω、104 dB、260 g）、HiFiMAN Ananda Nano（$499、93 dB、419 g）.
7. Who it is for — and who it is not
- Sport or rain: no water-resistance rating is published.
- Wireless-only listeners: this is a wired model needing a front end and a cable.
