How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a private, wireless, take-anywhere listening companion you can fold up and wear for days on a single charge, choose LORELEI B-C6; if you need a plug-in home stereo that plays your old CDs and cassettes and pulls in FM radio, choose M-Amazup Boombox CD Player. These two products share almost nothing except the ability to make sound. One is a pair of over-ear Bluetooth headphones. The other is a retro boombox system. Picking between them isn't about which is "better" — it's about which job you actually have.
• LORELEI B-C6 biggest strength: 50 hours of battery life from a 500mAh cell, a foldable 205 g frame, and Bluetooth 5.3 with a built-in mic — genuinely wearable all day.
• LORELEI B-C6 biggest trade-off: It's headphones only. No speakers, no radio, no disc playback. Everything is personal and in-ear.
• M-Amazup Boombox CD Player biggest strength: An all-in-one system — CD/CD-R/RW/MP3 playback, a cassette player and recorder, FM radio, Bluetooth, USB, TF card and AUX, all in one box.
• M-Amazup Boombox CD Player biggest trade-off: It's a 1.89 kg corded unit that needs a wall outlet or six C-cell batteries you supply yourself. Not something you carry in a pocket.
• Who LORELEI B-C6 is for: commuters, travelers, remote workers and anyone who wants music and calls on their own ears.
• Who M-Amazup Boombox CD Player is for: households with a shelf of CDs or cassettes, people who want a shared speaker in a room, and gift-buyers shopping for a retro music box.
The LORELEI B-C6 is built around one idea: keep the music going without babysitting a charger. The 500mAh battery is rated for 50 hours of playtime, and when it does run down you can plug in the included 3.5mm braided cable and keep listening in wired mode. That combination matters more than it sounds. Most wireless headphones become useless bricks when the battery dies — these don't, because the 3.5mm jack is a real fallback.
The physical design is aimed at long wear. It weighs 205 g, uses protein ear pads with memory foam, and the earcups rotate inward at 100° and fold inward at 120°, so the whole thing collapses to roughly 6.7 x 5.6 x 3.15 inches. The headband is multi-level adjustable, and the earpieces are over-ear circles with a leather carrying pouch in the box alongside a Type-C charging cable and a warranty card. For flights, train commutes, or a full day at a home-office desk, that fold-and-toss portability is the point.
Audio-wise you're getting dual 40mm dynamic drivers, 32 ohm impedance, 110 dB sensitivity, and a 20 Hz–20,000 Hz range — a mainstream tuning with the deep-bass emphasis the brand leans into. Bluetooth 5.3 handles the wireless link with a rated 10-meter range, and the built-in microphone covers calls. Controls are touch-based media controls, and the noise control is sound isolation rather than active cancellation, which is worth knowing before you buy.
Buy it if you want one pair of headphones for travel, commuting, calls and desk work, and you value battery life and folding size above everything else. Skip it if you need to fill a room with sound, play physical CDs or cassettes, or listen to FM radio — none of that exists here. Also skip it if you specifically want active noise cancellation; this model isolates passively.
The M-Amazup Boombox CD Player is the opposite philosophy. It's a stationary retro-modern system designed to be the music hub of a room. The centerpiece is a top-loading CD mechanism that reads CDs, CD-R/RW and MP3 discs with shuffle, repeat and programmable playback. If you have a stack of burned mix CDs or store-bought albums sitting in a drawer, this is the machine that gives them a purpose again.
Then there's the cassette side. This isn't just a tape player — it records. You can dub from CD, FM radio, Bluetooth, USB, AUX or an external source onto tape, which is a genuinely unusual feature in a modern combo unit and the reason someone with a box of blank tapes would pick this over a plain CD player. FM radio is covered with an upgraded antenna and one-click search, and there's no AM band, so set expectations there. Bluetooth, USB, TF card and AUX inputs round out the modern side, and supported formats include CD, CD-R, CD-RW, MP3 and WMA through a stereo two-speaker setup.
Power is the real dividing line. It runs on AC or six C-cell batteries, which are not included. The unit weighs 1.89 kg and measures about 10 x 2 x 2.7 inches, with a carry handle built into the top-loading body. So it's portable in the "carry it to the backyard" sense, not the "throw it in a bag" sense. There's also a headphone jack and bass boost, plus a remote control in the box.
Side-by-Side: Which Should You Choose?
• Best for battery life → LORELEI B-C6. 50 hours on a single charge, plus wired fallback when it runs out.
• Best for portability → LORELEI B-C6. 205 g and folds down to roughly 6.7 x 5.6 x 3.15 inches.
• Best for personal, private listening → LORELEI B-C6. Over-ear isolation and a built-in mic for calls.
• Best for playing physical media → M-Amazup Boombox CD Player. CD, CD-R/RW, MP3, WMA and cassette playback in one unit.
• Best for recording → M-Amazup Boombox CD Player. It dubs from CD, radio, Bluetooth, USB, AUX and external sources onto tape.
• Best for shared room audio → M-Amazup Boombox CD Player. Two stereo speakers, bass boost and a carry handle.
• Best for radio → M-Amazup Boombox CD Player. FM with an upgraded antenna and one-click search; LORELEI has no radio at all.
• Best for a gift with nostalgia appeal → M-Amazup Boombox CD Player. It's the kind of object that reads as a present the moment it's unboxed.
In my opinion, the LORELEI B-C6 wins for the majority of individual buyers. It's lighter, it runs for 50 hours untethered, it folds flat, it handles calls, and it does the one thing most people actually need from audio gear: follow them around all day. I'd pick it for commuting, travel and desk work without hesitation.
I'd only steer you to the M-Amazup Boombox CD Player if your music lives on discs and tapes, or if you want a speaker the whole room can hear. That's a real, specific need — and for that buyer, no pair of headphones is a substitute. Check the current price on Amazon for whichever one matches your job, since the two serve completely different purposes.
FAQ
Yes, based on the specs. The 50-hour battery, 205 g weight and foldable earcups are all aimed at travel, and the 3.5mm cable lets you keep listening if the battery runs low. Note it uses passive sound isolation, not active noise cancellation.
Yes — it runs on AC or six C-cell batteries, but the batteries are not included, so factor that in. It weighs 1.89 kg, so it's a carry-to-the-garden portable rather than a pocket device.
Yes. It supports CD, CD-R, CD-RW, MP3 and WMA, and it can record onto cassette from CD, FM radio, Bluetooth, USB, AUX and external sources. That recording feature is the main reason to choose it over a simpler CD player.
That depends entirely on the job. If you want private wireless listening, the LORELEI B-C6 covers more of your daily needs. If you want to revive a CD and cassette collection in one box, the M-Amazup is the only one of the two that can do it. Compare the current prices on Amazon before deciding.
