If you want one box that gets a BlueParrott headset charged at a desk or nightstand with nothing else to buy, choose LSSBUUD USB Micro Wall; if you need a spare magnetic charging cord for an RR Sports AC889 swimming headphone you already own, choose WUNIAK Charging Cable.
• LSSBUUD USB Micro Wall — biggest trade-off: the Micro USB end only fits the old-version BlueParrott B450-XT, not the newer Type-C version, so you must check your headset's port before buying.
• WUNIAK Charging Cable — biggest strength: a two-pack of short 60 cm magnetic charging cables built specifically for the RR Sports AC889, with a PTC voltage regulator inside to guard against overcurrent.
• WUNIAK Charging Cable — biggest trade-off: it is a cable-only accessory, so you supply your own USB power source, and it fits one specific headphone model.
• Who each pick is for: LSSBUUD for someone who wants a plug-and-cable setup for a compatible BlueParrott headset; WUNIAK for an AC889 owner replacing a lost or worn charging cord.
The LSSBUUD set is the more complete of the two. You get a wall-mounted charging block plus a 5 ft Micro USB to USB A cable, and the block plugs into a standard North American Type A two-pin outlet. That 5 ft length is the detail I keep coming back to: it is long enough to reach from a wall outlet to a sofa arm, a bedside table or a desk shelf, so you are not forced to leave the headset balanced on the floor while it charges. The single USB 2.0 port keeps things simple, and the cable itself is rated up to 3A and 15W at 5V DC, which is more than enough headroom for a Bluetooth headset. Data transfer is listed at up to 480Mbps, so it doubles as a sync cable if you ever need one.
The build is PVC with a thickened jacket and a 100% copper wire core, and the spec sheet puts the bending life at over 8,000 cycles. The enclosure is plastic and the design is wall-mounted, which suits a fixed spot like a bedroom, office or library charging corner. It also ships with a 12-month warranty and a 30-day return window, which is worth knowing if you are buying for a work headset you depend on daily.
WUNIAK Charging Cable: Who It's For
The WUNIAK cable is a much narrower tool, and it is honest about that. It is a magnetic USB charging cable made for the RR Sports AC889 bone conduction swimming headphones — the kind of headphone that uses a magnetic contact charger rather than a standard port. If your original AC889 cable is lost, chewed up or frayed, this is a direct replacement rather than a workaround.
The feature I like most is the voltage regulator (PTC) built into the cable. Magnetic charging contacts on swimming headphones are exposed to water and sweat, and a small regulator that limits overcurrent is a genuinely sensible safeguard for a device you wear near your head. The connectors are male-to-male with four pins, the cable type is copper wire, and it is black.
The length is the other defining trait: 60 cm, roughly two feet. That is short on purpose. It is meant to dangle from a laptop, a power bank or a wall adapter while you sit nearby, and it coils up small enough to live in a gym bag, a car console or a swim kit. You get two of them in the pack, which is the practical part — one for home, one for the bag, so you are never stuck without a charge before a session.
Who should skip it: anyone who does not own an RR Sports AC889. There is no mention of other compatible models, and a magnetic cable is not something you can improvise onto a different device. Also skip it if you want a wall plug included — there is none here, just the cable. WUNIAK backs it with 24/7 email support.
• Best for a BlueParrott headset with a Micro USB port → LSSBUUD USB Micro Wall. The connector, the 5 ft reach and the included wall block all line up with that job.
• Best for the newer Type-C B450-XT → neither. LSSBUUD explicitly does not fit it, and WUNIAK fits only the AC889.
• Best for RR Sports AC889 owners → WUNIAK Charging Cable. It is purpose-built for that headphone's magnetic charging contacts.
• Best for a complete out-of-the-box setup → LSSBUUD USB Micro Wall. Wall block plus cable in one purchase, versus cable only.
• Best for travel and gym bags → WUNIAK Charging Cable. The 60 cm length packs down small, and you get two so one can live in your bag permanently.
• Best for long cable runs across a room → LSSBUUD USB Micro Wall. 5 ft beats 60 cm every time when the outlet is not next to your seat.
• Best for charging safety circuitry → WUNIAK Charging Cable. The built-in PTC voltage regulator is the more deliberate overcurrent safeguard of the two.
• Best for charging speed headroom → LSSBUUD USB Micro Wall. It is rated to 3A / 15W at 5V, and it also handles 480Mbps data if you need it.
In my opinion, the LSSBUUD USB Micro Wall is the one I would buy for most people reading this, because it solves the whole problem in a single box — plug, cable, length and a warranty — and it covers the BlueParrott models most people are charging. But that recommendation is conditional, and I want to be clear about it: check your headset's port first. If you own the old-version B450-XT or another Micro USB BlueParrott, buy it with confidence. If you own the newer Type-C B450-XT or an RR Sports AC889, buy the WUNIAK instead — a cable that fits is worth more than a bundle that does not. Check the current price on Amazon before you commit, since that is the one thing that can tip a close call.
No. It fits the B350-XT, B450-XT old version, S450-XT and B550-XT with a Micro USB port. It does not fit the newer B450-XT with a Type-C connector, so verify your port before ordering.
Only the AC889 is listed as compatible. It is a magnetic-contact cable designed for that specific bone conduction model, so it is not a general-purpose replacement cord.
Yes. The WUNIAK pack contains two 60 cm magnetic cables only. You charge from a USB port on a PC, laptop, power bank or wall adapter that you already own.
It depends on what you already have. LSSBUUD gives you a wall block and a 5 ft cable together for a BlueParrott headset; WUNIAK gives you two short spare cables for one specific headphone. Compare the current prices on Amazon and match it to the device you actually need to charge.
