If you want a lightweight wired headphone that also plays music straight from a TF card and folds down small for travel, choose FASJ HiFi Headphone; if you need active noise cancelling, Bluetooth freedom and long battery life for flights or noisy offices, choose Bose QuietComfort 45.
• FASJ HiFi Headphone — biggest strength: a wired 3.5 mm over-ear design that also reads MP3 files from a TF card, pulls in FM radio automatically, accepts any LINE-IN source and lets you switch EQ profiles — a lot of standalone playback options in one foldable package.
• FASJ HiFi Headphone — biggest trade-off: it is wired only, relies on sound isolation rather than active noise cancelling, and its 32 ohm dynamic drivers are built for everyday listening rather than silencing a plane cabin.
• Bose QuietComfort 45 — biggest strength: proprietary active noise cancelling paired with Bluetooth 5.1 wireless audio, adjustable EQ and up to 22–24 hours of playtime per charge.
• Bose QuietComfort 45 — biggest trade-off: it has no headphone jack at all, so anything you want to hear has to come over Bluetooth, and this listing is a renewed unit backed by a 90-day limited warranty rather than a full manufacturer term.
• Choose FASJ if you want a cheap-to-own wired backup set, an offline TF-card player, or a foldable pair for movies and music at a desk.
• Choose Bose if noise cancelling, wireless convenience and all-day battery matter more to you than a cable.
The FASJ HiFi Headphone is an over-ear wired headphone with a 3.5 mm jack, 32 ohm impedance and dynamic drivers covering the standard 20 Hz – 20,000 Hz range. Sensitivity is rated at 103 dB ± 3 dB and the signal-to-noise ratio at 93 dB, with output power listed at 20 mW × 2 into 32 ohms and maximum output distortion of ≤1%. In plain terms, that is a sensitive, easy-to-drive headphone — the kind of load a phone, laptop or cheap MP3 player can push without a separate amp.
What makes it unusual is everything bolted on around the cable. It plays MP3 files stored on a TF card, which means it can work as a standalone player with no phone attached. It accepts any external LINE-IN audio source. It has FM automatic search, so it can pull in radio stations on its own. And there is an EQ sound switching function, so you can nudge the tuning without touching your source device. The ear cups rotate, the headband adjusts, and the whole thing folds down to a compact size — a genuinely portable shape for a bag or a drawer.
Build-wise, it uses synthetic materials with some lightweight metal, skin-friendly ear pads, a rounded over-ear cup shape, a black finish, touch-style media controls and sound isolation for blocking out a bit of background noise. FASJ covers it with a one-year warranty.
This is the pair I would point at a few specific people: someone who wants a wired set for a desktop or laptop, a traveler who wants a foldable second headphone they won't stress about, or anyone who likes the idea of loading songs onto a card and skipping the phone entirely. I would steer you elsewhere if you fly a lot, work in a loud open office, or simply refuse to deal with a cable — sound isolation is not the same thing as active noise cancelling, and there is no Bluetooth here at all.
The Bose QuietComfort 45 is an over-ear wireless headphone built around Bose's proprietary noise cancelling technology — the headline feature, and the reason most people look at this model in the first place. It connects over Bluetooth 5.1, which is a modern, stable wireless standard, and it drives dynamic drivers across the same 20 Hz – 20,000 Hz range as the FASJ. You also get adjustable EQ, so you can shape the sound rather than accept one fixed tuning.
Battery life is the second big selling point: the listing states up to 22 hours of playtime, while the description mentions up to 24 hours on a single charge. Either way, that is a full working day and then some, which matters when the alternative is hunting for a cable. The set is finished in black plastic, comes with a soft carry case, and weighs roughly 0.3 kg — light enough to wear for long stretches without feeling like a brick on your head. Controls are push-button media controls, and the bundle includes the headphones plus the case.
One detail you should weigh honestly: this particular listing is a renewed unit, and the warranty is a 90-day limited term rather than a full-length new-product warranty. That is not a dealbreaker — renewed hardware is a legitimate way to get into a premium model — but it changes how you should think about risk. If long-term coverage is important to you, factor that in.
I would recommend the Bose QuietComfort 45 to commuters, frequent flyers, open-office workers and anyone who wants to disappear into their own audio without cranking the volume. I would not recommend it to someone who needs a wired connection, wants to avoid charging, or prefers to keep a cable as a guaranteed fallback — there is no headphone jack on this model.
• Best for noise cancelling → Bose QuietComfort 45. Active noise cancellation versus the FASJ's passive sound isolation is the single biggest functional gap between these two.
• Best for wireless freedom → Bose QuietComfort 45. Bluetooth 5.1 with no cable at all, against a wired-only 3.5 mm connection on the FASJ.
• Best for battery life → Bose QuietComfort 45. Up to 22–24 hours per charge, where the FASJ draws power from its source and has no battery figure at all.
• Best for offline, phone-free playback → FASJ HiFi Headphone. TF card MP3 playback and FM automatic search are things the Bose simply does not do.
• Best for connecting to older gear → FASJ HiFi Headphone. A 3.5 mm jack and LINE-IN input work with almost anything; the Bose has no jack, so a wired source is out.
• Best for travel packing → FASJ HiFi Headphone. It folds to a compact size, while the Bose ships with a soft case but does not fold.
• Best for tuning the sound → a tie, with a caveat. Both offer EQ adjustment, but the Bose's is adjustable within its app-style control set while the FASJ uses a simpler EQ switching function.
• Best for low-risk ownership → FASJ HiFi Headphone. A one-year warranty beats the Bose's 90-day limited term on this renewed listing, even though the Bose is the more advanced product.
In my opinion, the Bose QuietComfort 45 is the better headphone for most people, and it is the one I would buy. Active noise cancelling, Bluetooth 5.1, adjustable EQ and 22–24 hours of battery solve the problems most listeners actually have — commutes, flights, noisy rooms, and not wanting a cable trailing across a desk. The FASJ HiFi Headphone is the smarter pick only if your needs are narrower and more specific: wired reliability, TF-card playback, FM radio and a foldable shape. Buy the Bose for the experience; buy the FASJ for the flexibility.
FAQ
No. The spec sheet lists it as "without jack," so it is wireless-only over Bluetooth. If you need a 3.5 mm wired connection, the FASJ HiFi Headphone is the one with the jack.
Yes. It supports MP3 playback from a TF card and has FM automatic search, plus LINE-IN for external audio sources. That makes it usable as a standalone player, which the Bose cannot do.
It is worth knowing. This listing is a renewed unit with a 90-day limited warranty, compared with the FASJ's one-year coverage. Renewed hardware can be a sensible route to a premium model, but weigh the shorter warranty against your own risk tolerance.
