If you want a single-purpose charging kit built specifically for older micro-USB BlueParrott headsets, choose LSSBUUD USB Micro Wall; if you need true wireless earbuds for calls, music and workouts, choose Rinsmola Earbuds. These two products barely overlap — one is a wall charger plus cable, the other is a pair of Bluetooth earbuds — so the right answer comes down to the job you actually need done, not brand loyalty.
• LSSBUUD USB Micro Wall — biggest strength: a complete 15W charging setup (wall block + 5 ft micro-USB to USB-A cable) aimed at a narrow, specific family of BlueParrott headsets, with data transfer up to 480Mbps and a cable rated for more than 8,000 bends.
• LSSBUUD USB Micro Wall — biggest trade-off: it only fits micro-USB devices, and LSSBUUD explicitly warns it will not work with the newer USB-C version of the B450-XT, so you must check your headset first.
• Rinsmola Earbuds — biggest strength: Bluetooth 5.4 wireless audio with 14.2mm dynamic drivers, 4 ENC call microphones, up to 48 hours total playtime with the case, and IP7 water resistance.
• Rinsmola Earbuds — biggest trade-off: it is a wireless audio product, not a charging accessory — it has no wall plug and nothing in common with a headset charging kit.
• Pick LSSBUUD if your only goal is keeping a compatible BlueParrott headset topped up at your desk, sofa or bedside.
• Pick Rinsmola if you actually want earbuds for music, calls and running, and you already have a USB-C charging source.
The LSSBUUD USB Micro Wall is a bundled charging solution: one wall-mounted USB-A charger block plus a 5 ft micro-USB to USB-A cable. The output is 15 watts at 5V/3A, and the cable also handles data transfer at up to 480Mbps. The whole package is plastic-bodied, compact and easy to toss in a bag, and LSSBUUD rates the cable's bending life at over 8,000 cycles thanks to a thickened PVC jacket and a copper wire core. It's the kind of accessory you buy because a specific device needs it — not because it's exciting.
And that specific device matters enormously here. LSSBUUD lists compatibility with the BlueParrott B350-XT, B450-XT, S450-XT, B550-XT and their variant spellings (B350XT, B450XT). The critical detail: this is a micro-USB cable, so it fits the older micro-USB version of the B450-XT but not the newer USB-C version. LSSBUUD says so plainly, and even notes that people have bought it by mistake. If you own one of the listed headsets and you're sure it charges over micro-USB, this is a clean, complete answer — wall plug and cable in one box, no hunting for a matching brick. The 5 ft reach is genuinely useful for charging on a bedside table, on a sofa arm or across a desk while you keep wearing the headset.
Who should buy it: anyone with a compatible micro-USB BlueParrott headset who wants a dedicated wall charger and cable, or who wants a spare to leave at the office. Who should skip it: anyone with the newer USB-C B450-XT, anyone with USB-C headsets generally, and anyone shopping for audio gear — this product makes no sound at all. If you're not sure which connector your headset uses, check the port before ordering, because there is no adapter in the box.
The Rinsmola Earbuds are true wireless in-ear headphones built around Bluetooth 5.4, with a stated 4Mbps transmission speed and a stable connection range of up to 15 meters. In practice that means the earbuds pair automatically with the last device you used after the first setup, and Rinsmola claims the newer chip largely removes audio/video delay — the spec sheet lists audio latency of 41 milliseconds, which is a reasonable figure for everyday video watching. Inside each bud sits a 14.2mm dynamic driver with 32 ohm impedance, 108dB sensitivity and a 20KHz frequency response, tuned for clear treble and punchy bass. You can also use either bud alone in mono mode.
Calls are a headline feature: four ENC microphones work with an algorithm to keep your voice clear and push background noise down. For anyone taking meetings on the move, that's the most practically valuable spec here. Battery life is the other big number — 8 hours per charge, up to 48 hours total with the charging case, which recharges over USB-C in about 1.5 hours and shows dual LED battery indicators. The case itself is tiny (roughly 2 × 3 × 4 cm, 35g) and pocketable.
Fit and durability look workout-oriented. The buds use an arc-shaped, ergonomic in-ear design, ship with six silicone tips in S/M/L, and carry an IP7 water-resistance rating — fine for sweat, rain and dust, though not for swimming. Controls are touch-based: volume, track skipping, play/pause, call answering and voice assistant. They're compatible with iOS, Android, laptops, computers and smartwatches. This particular version is finished in Pink, and the body is ABS/plastic — worth knowing if you wanted a neutral color. Rinsmola backs it with a 2-year warranty plus a 1-month return window for quality problems.
Side-by-Side: Which Should You Choose?
• Best for charging a BlueParrott headset → LSSBUUD USB Micro Wall. It's the only one of the two that charges anything.
• Best for battery life (on the go) → Rinsmola Earbuds, with 8 hours per charge and up to 48 hours with the case.
• Best for call clarity → Rinsmola Earbuds, thanks to its 4 ENC microphones.
• Best for workouts and rain → Rinsmola Earbuds, rated IP7 waterproof.
• Best for a desk or bedside charging setup → LSSBUUD USB Micro Wall, with its 5 ft cable and wall-mounted block.
• Best for travel convenience → Rinsmola Earbuds. A 35g case in your pocket beats carrying a charger and cable.
• Best for a wired, no-pairing solution → LSSBUUD USB Micro Wall. Nothing to connect, nothing to charge in the earbuds sense.
• Best for someone replacing a lost headset charger → LSSBUUD USB Micro Wall, but only if your headset uses micro-USB.
• Best for a phone or laptop user who wants audio → Rinsmola Earbuds, compatible with iOS, Android, laptops and smartwatches.
My Verdict
No. It fits the micro-USB versions of the B350-XT, B450-XT, S450-XT and B550-XT. LSSBUUD specifically warns it will not work with the newer USB-C version of the B450-XT, so confirm your headset's port before buying.
No. The box includes the two earbuds, the charging case, six silicone ear tips in S/M/L, a USB-C cable and a manual. You'll need your own USB power adapter to plug that cable into.
The Rinsmola Earbuds — they're the only one of the two with microphones. They use four ENC mics and an algorithm to reduce background noise and keep your voice clear during calls.
