If you want a portable CD player that can also pull FM radio, read SD cards, play MP3 discs and pipe audio into your car three different ways, choose KLIM Journey; if you need safe, ultra-light open-ear Bluetooth headphones for a child to wear at school, on trips or during sports, choose iClever OWS01.
These two products barely share a category, and that's the point. One is a modern take on the discman. The other is a kids' wearable speaker-style headphone. The "versus" only makes sense if you're deciding which one solves the problem sitting in front of you right now — physical CDs and car audio, or a kid who needs to hear the world while listening to music. Here's how I'd split them.
• KLIM Journey — biggest strength: enormous format flexibility. CD, CD-R/RW, MP3 discs, SD card, FM radio, FM transmission, Bluetooth, AUX, plus a rechargeable battery and two headphone jacks.
• KLIM Journey — biggest trade-off: it's a disc-based device with moving parts, and KLIM itself flags that Bluetooth pairing with some car infotainment systems can be inconsistent; the FM transmitter is the fallback.
• iClever OWS01 — biggest strength: a genuinely kid-focused design — open-ear air conduction, a 74/85 dBA volume limit, 0.8 oz of weight, and a memory-steel band that bends 360° without deforming.
• iClever OWS01 — biggest trade-off: it's wireless only. No jack, no wired fallback, no CD or SD playback, and it's aimed at children rather than adult listeners.
• Who KLIM Journey is for: anyone with a shelf of CDs, an older car without streaming, or a household that wants one box that plays almost any physical or broadcast format.
• Who iClever OWS01 is for: parents buying a first real pair of headphones for a kid, especially for school, travel and outdoor play.
The KLIM Journey is the more unusual product of the two, and in my opinion it's the more interesting one. It's a single-disc portable player measuring roughly 5.5 by 5.5 by 1.1 inches and weighing about 0.25 kg — small enough to live in a glovebox or a backpack pocket, big enough to hold a proper CD mechanism and a rechargeable lithium-ion cell. That battery is the first thing that separates it from the bargain disc players you'll find floating around: no hunting for AAs, just a USB-C cable. It ships with KLIM Fusion wired earphones, a carry pouch and earphone accessories.
Around that core, you get FM radio reception, an SD card reader, MP3 disc support, speed control, an equalizer, and recording. There's also anti-shock protection that preloads up to 100 seconds of audio so the disc doesn't skip when you're walking, commuting or moving around. Two 3.5 mm outputs mean two people can listen at once with separate earphones — a small feature that matters on long drives or flights with a kid.
Who should buy it? Someone with a CD collection they refuse to abandon. Someone driving a car old enough that streaming isn't built in and AUX is unreliable. Someone who wants one device that handles discs, memory cards and radio in a car, at home, or on a desk. Who should skip it? Anyone who has fully moved to streaming and just wants headphones — the Journey is a player first and a Bluetooth transmitter second, and it's not trying to be a music app. Also skip it if you want a pocket device for a young child; it's an adult-oriented piece of electronics with discs and a laser inside.
iClever OWS01: Who It's For
The iClever OWS01 is a completely different proposition: open-ear air conduction headphones built specifically for kids. Instead of pushing sound into the ear canal, they sit outside it and let sound travel in naturally. For a parent, that non-in-ear approach is the whole pitch — your child stays aware of traffic, teachers, teammates and anyone calling their name, and nothing is jammed into a growing ear canal.
The safety engineering is where iClever has clearly spent its effort. There's a 74/85 dBA volume limit, which caps how loud the headphones can go so a child can't casually crank them into hearing-damage territory. The housing is soft TPE, described as gentle on delicate skin, and the fit uses a three-point pressure dispersion system rather than clamping the head. At 0.8 oz, these are about as light as headphones get, which is exactly what you want for something worn all day at school or through a long travel day. The back-hanging section uses a memory steel wire that bends up to 360° without deforming — a genuinely useful spec for a product that will be stuffed into backpacks and bent by small hands.
On audio, you get 14.2 mm dynamic drivers with a 20 Hz–20,000 Hz range, plus Dynamic Range Control that lifts bass while keeping vocals bright and clear. Bluetooth 5.4 handles the connection, and iClever lists compatibility with phones, laptops, tablets, PCs and smartwatches. Controls are simple physical buttons for volume and playback, which is the right call for kids — nothing to swipe accidentally.
Side-by-Side: Which Should You Choose?
• Best for playing physical CDs → KLIM Journey. Disc playback, CD-R/RW support and MP3 discs are the core of what it does.
• Best for car audio in an older vehicle → KLIM Journey. AUX, Bluetooth and FM transmission give you three routes, so you're rarely stuck.
• Best for a kid's everyday headphones → iClever OWS01. Open-ear, volume-limited and 0.8 oz light, designed for children from the ground up.
• Best for safety and hearing protection → iClever OWS01. The 74/85 dBA limit and non-in-ear design are the decisive features.
• Best for shared listening → KLIM Journey. Two 3.5 mm outputs let two people listen to the same disc at the same time.
• Best for gym, running or commuting with a CD → KLIM Journey. The anti-shock chip preloads up to 100 seconds to keep playback uninterrupted.
• Best for travel with a child → iClever OWS01. Ultra-light, bendable and wireless, with no disc mechanism to protect.
• Best for someone who wants one device for radio, SD cards and discs → KLIM Journey. It covers formats the OWS01 doesn't touch at all.
If I had to pick one for myself, I'd buy the KLIM Journey. I still own CDs, I've dealt with cars that only offer AUX or FM, and a player that handles discs, SD cards, radio and three car connection methods is the more useful object in my life — the anti-shock buffer and rechargeable battery seal it. I'd only steer you to the iClever OWS01 instead if the actual buyer is a child, in which case the volume limit, open-ear awareness and 0.8 oz build make it the obviously correct choice. Different jobs, different winners. Check the current price on Amazon before you commit, since value depends on what you're replacing.
FAQ
Yes. It has three connection options: AUX via the included cable, Bluetooth, and FM transmission that broadcasts audio to your car's FM radio. KLIM notes Bluetooth compatibility varies by car, so FM transmission is the reliable fallback.
No. The OWS01 is wireless only, with no headphone jack — it connects over Bluetooth 5.4 to phones, tablets, laptops, PCs and smartwatches.
They're durable in different ways. The iClever OWS01 is built for rough handling, with a memory steel wire that bends 360° without deforming and a very light 0.8 oz body. The KLIM Journey is built around precision components and covered by a 5-year assurance, but it contains a disc drive and laser, so it needs more careful handling.
