How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want an all-in-one wearable FM radio you can wear on your head while you walk, jog or do chores, choose Flyoukki Personal FM Radio; if you need a small retro-style radio that also plays and records cassette tapes, choose Jensen ® CR-100.
• Flyoukki Personal FM Radio — biggest strength: a headphone-and-radio combo with automatic FM search and up to 11 preset stations, over-ear passive noise blocking, 15 volume levels, and a 3.5 mm AUX input for a computer or MP3 player.
• Flyoukki Personal FM Radio — biggest trade-off: FM only, no AM, no speaker, and it needs 2 AA batteries that aren't included.
• Jensen ® CR-100 — biggest strength: a true multi-source retro unit — cassette playback and recording, built-in condenser microphone, AM/FM tuner, built-in speaker, headphone jack and recorder jack.
• Jensen ® CR-100 — biggest trade-off: it's a handheld box, not something you wear; no Bluetooth, not water resistant, and it also runs on 2 AA batteries (or an AC adapter) that aren't included.
• Who each is for: the Flyoukki is for someone who wants hands-free FM listening while moving. The Jensen is for someone who wants a small nostalgic tape/radio player to set on a table, shelf or picnic blanket.
The Flyoukki Personal FM Radio is, at its core, a pair of over-ear headphones with an FM tuner built into the headset. It supports FM only — there's no AM band — and the automatic search-and-store function can lock in up to 11 preset stations you cycle through with simple push buttons. The design is deliberately plain: an adjustable head strap, over-ear foam/silicone cushions, plastic housing, and a foldable, compact shape that's easy to toss in a bag. It weighs 0.2 kg.
What it does best is keep your hands free. Because the radio lives in the headphones, there's no separate device to hold, no dangling cord to a tuner, and no speaker to bother the people around you. The passive noise cancellation is there to muffle everyday distractions — a TV in the next room, a dog barking, chatter in a public space. Flyoukki is upfront that it can't cut extremely loud noise, so treat it as a softener, not a silencer. There's also a 15-level volume control, a dynamic driver rated 20 Hz–20,000 Hz, and a heavy-bass emphasis for music.
Beyond radio, the 3.5 mm AUX input and included cable let you plug into a computer, MP3 player or phone and treat it as ordinary wired headphones. That's the quiet advantage here: one device covers your radio walks and your desk listening.
Jensen ® CR-100: Who It's For
The Jensen ® CR-100 is a different animal entirely. This is the teal Limited Edition of a retro-styled personal cassette player/recorder with an AM/FM radio built in. It has a mini speaker on the front, a built-in condenser microphone, and the ability to record — from the radio or straight through the mic. It measures roughly 4.02" long, 1.89" wide and 5.35" tall, weighs 0.23 kg, and runs on 2 AA batteries or an AC adapter. Neither is included.
Its personality is nostalgia plus utility. You can dig out old mix tapes and audiobooks, or just use the AM/FM stereo tuner for talk radio and music. There's an LED display, a built-in FM antenna, a headphone jack for private listening, and a recorder jack for input. Audio output is stereo, with a 5-watt maximum speaker output, so it can fill a small room or a picnic table. Jensen backs it with a one-year manufacturer warranty.
The recording side deserves attention, because that's what separates the CR-100 from a plain radio. Recording off the radio or via the condenser mic turns it into a capture tool — voice memos, a song off the air, a quick idea. The trade-offs are equally clear: this is a handheld unit you set down or carry in a bag, not something you wear while running. It's not water resistant, so keep it out of the rain, and the only wired connectivity listed is USB plus the headphone and recorder jacks — no wireless streaming.
Who should buy it: cassette collectors, retro-gadget fans, people who want a compact AM/FM set with a speaker for a kitchen counter, garage, beach bag or ball game, and anyone who wants simple recording without a phone app. Who should skip it: runners and gym users who need hands-free audio, anyone who wants Bluetooth, and anyone who'd rather not deal with tapes at all.
Side-by-Side: Which Should You Choose?
• Best for AM stations → Jensen ® CR-100. The Jensen tunes both AM and FM; the Flyoukki is FM only.
• Best for tape playback and recording → Jensen ® CR-100. Cassette playback, a built-in mic, and radio/mic recording are things the Flyoukki simply doesn't do.
• Best for blocking out background noise → Flyoukki Personal FM Radio. Over-ear cushions with passive noise cancellation soften TVs, barking dogs and public chatter — though not extremely loud sound.
• Best for sharing audio with others → Jensen ® CR-100. The front-facing mini speaker and 5-watt max output let a small group listen; the Flyoukki is a private, headphone-only experience.
• Best for plugging into a computer or MP3 player → Flyoukki Personal FM Radio. The 3.5 mm AUX jack and included cable make it dual-purpose as wired headphones.
• Best for simple controls for kids or seniors → Flyoukki Personal FM Radio. Push-button media controls and a 15-level volume range keep operation basic.
• Best for a nostalgia display piece → Jensen ® CR-100. The retro styling in teal Limited Edition is part of the appeal, not an afterthought.
If I had to pick one for the way most people actually listen — walking, jogging, chores, hands free — I'd buy the Flyoukki Personal FM Radio. In my opinion it wins on everyday usefulness: the tuner, the presets, the over-ear fit, the AUX mode and the simple buttons all point at one job done well, and there's no tape to find or rewind.
I'd only switch to the Jensen ® CR-100 if tapes and recording matter to you. It's the more versatile machine — AM/FM, cassette playback, a mic, a speaker, a recorder jack — but you have to want those extras, and you have to be fine with a handheld box rather than a wearable. Check the current price on Amazon for both before you commit, since that's the one factor that can tip a close call.
No. The Flyoukki is a pair of over-ear headphones with an FM tuner built in. The Jensen ® CR-100 is a portable cassette player/recorder with an AM/FM radio, built-in speaker and microphone. Different form factors, different jobs.
No — it's FM only. If you specifically want AM talk or sports stations, the Jensen ® CR-100 tunes both AM and FM, which makes it the better fit.
Neither includes batteries. Both run on 2 AA batteries, and the Jensen ® CR-100 can alternatively use an AC adapter. You'll need to supply power either way.
The Flyoukki Personal FM Radio, in my opinion. It's a wearable headset with an adjustable strap and foldable design, so it's built around moving with you. The Jensen ® CR-100 is a handheld unit intended to sit on a surface or ride in a bag.
