The short answer
The FiiO JT1 is a closed-back wired option to compare. FiiO lists 32Ω impedance and 103dB/Vrms sensitivity. Try a compatible headphone source before buying a separate amplifier; sufficient level and microphone support depend on the exact device. The supplied cable has an inline microphone and detaches, and the ear pads come off without tools — the two parts that normally wear out first.
1. FiiO's published specifications
| Item | Published value |
|---|---|
| Type | Closed-back, over-ear, wired |
| Driver | 50mm dynamic, PEK + PU + aluminium composite diaphragm |
| Magnets / voice coil | N52 magnets, CCAW voice coil |
| Impedance | 32Ω at 1kHz |
| Sensitivity | 103dB/Vrms at 1kHz (a minority of listings quote 113dB/Vrms — see section 5) |
| Frequency response | 15Hz – 30kHz |
| Cable | Detachable, dual 3.5mm TRS, oxygen-free copper, about 1.5m, inline microphone |
| Weight | About 355g excluding the cable |
| Headband and pads | Adaptive leather-wrapped headband; quick-release ear pads |
| In the box | Microphone cable, 3.5mm-to-6.35mm adapter, storage pouch |
The 32Ω impedance with that sensitivity is the practical headline: this is a headphone designed to run from ordinary sources. FiiO's own materials describe it as easy to drive and pair it with its small USB dongles — our dongle guide covers that route if your device has no headphone socket. Because it is closed-back, it also blocks more outside noise than the open models in our open-back comparison, which makes it a candidate for shared rooms and travel.
2. What the listing usually leaves out
- The cable is the microphone. The inline mic sits in the detachable cable, so replacing the cable for a different length also removes microphone support. If you need voice on a PC that has separate headphone and microphone sockets, you will also need the correct splitter.
- The 6.35mm adapter is included, a balanced cable is not. There is no 4.4mm or 2.5mm balanced cable in the box; the dual 3.5mm sockets are single-ended connections.
- Colourways differ by listing. The JT1 has been sold in several finishes and the photo on a retailer page does not always match the variant you selected. Confirm the colour in the variant dropdown before ordering.
- Weight is real. About 355g without the cable is heavier than most IEMs in our budget IEM shortlist, and heavier than the 240g Sennheiser models below. That is a comfort question, not a quality one.
- Warranty is regional. FiiO administers service through its distributors, so the terms you actually get come from the seller you buy from. Read that part of the listing before ordering.
3. Do you need an amplifier?
Try a compatible source first. Impedance alone does not establish the required amplifier; headphone sensitivity and available output also matter. If your device has no headphone socket at all — many recent phones — a USB dongle is the smallest fix, and that is a different purchase from a desktop amplifier.
Buy an amplifier only for a specific reason you can name: your present source cannot provide sufficient clean level, or you need a verified input or output your current source lacks. Our headphone amplifier guide sets out the different device types, and the gaming guide covers latency and microphone support if voice chat is the reason you are looking.

JT1 detail page4. What to compare it against
Three comparisons are worth making before you commit, all of them about use rather than sound:
- Open-back and lighter: the Sennheiser HD 560S is 240g and open, so it leaks sound both ways. If you share a room or commute, stay closed.
- Another open-back option: compare the Sennheiser HD 599 SE. Check the current quote rather than assuming which model costs less.
- Wired IEMs instead: if you do not need over-ear cups, the wired IEM starting points are covered in best budget IEMs in Canada, and the ordering and duty side is in where to buy IEMs in Canada.

Sennheiser HD 560S — check the current retailer quote
The lighter, open-back alternative at 240g. It leaks sound both ways, so it suits a room of your own rather than a shared one.
HD 560S detail page5. What we could not verify
- Sensitivity basis. FiiO's published sheet gives 103dB/Vrms at 1kHz, and one retailer lists the same figure as dB/mW; a second lists 113dB/Vrms. The numbers disagree, so we quote the published figure and treat the alternative as unconfirmed.
- Current stock. Check the selected retailer offer and its delivery estimate before buying.
- Warranty length in Canada for a specific seller — see section 2.
- Our own catalogue values. The record behind the product page was corrected on 20 September 2026 to FiiO's published pair (103dB/Vrms, 15Hz–30kHz). The earlier 100dB/mW and 12Hz–40kHz values came from a seller listing and are retired.
