• NUBWO HW02 – biggest strength: a full on-ear headset with a boom microphone, dual USB-C/3.5mm connectivity and an in-line volume control, so it works out of the box for calls and webinars.
• NUBWO HW02 – biggest trade-off: it's a wired, on-ear headset with a 27 mm driver and no active noise cancellation, so it's built for voice work rather than immersive music listening.
• Hizsoaor Replacement Solo 4 – biggest strength: a 4.6 ft OFC copper cable with dual 3.5mm plugs, an inline mic and remote, designed to replace a damaged or lost headphone cable.
• Hizsoaor Replacement Solo 4 – biggest trade-off: it is a cable, not a headset — it only helps if you already own compatible headphones, and its remote/mic functions are limited on Android and Samsung devices.
• Who NUBWO HW02 is for: anyone who needs a working headset for office, call center or home-office voice use.
• Who Hizsoaor Replacement Solo 4 is for: anyone who already owns compatible Beats or similar headphones and just needs a fresh cable with mic support.
The NUBWO HW02 is a complete, self-contained wired headset. It pairs a 27 mm dynamic driver with a boom microphone, so the whole point of the product is two-way communication: talking on calls, joining webinars, and taking part in softphone or call-center work. The impedance is rated at 32 ohm with a sensitivity of 98 dB and a frequency range of 20 Hz to 20,000 Hz — a sensible, voice-first tuning that will handle speech clearly and play music well enough for background listening, without pretending to be an audiophile headphone.
What makes it flexible is the connectivity. The model name is "TYPE C+3.5mm," which means it ships with both a USB connection and 3.5mm compatibility. That matters in the real world: a laptop that only has USB-C or USB-A ports works, and a phone or tablet with a headphone jack also works. The manufacturer also states the headset is optimized for major communication software and that it includes some shortcuts for convenience, which is exactly what you want if you live in a meeting app all day. The in-line control handles volume, and it's a physical button rather than a touch surface — a small thing, but a button you can find by feel mid-call is genuinely useful.
Who should buy it: anyone setting up a home office, a small call center desk, or a shared workspace who needs one headset that just works with both modern USB ports and older 3.5mm jacks. Who should skip it: someone shopping purely for music, someone who wants wireless freedom, or someone who wants active noise cancellation — the noise control field is listed as none. There's also a 2-year manufacturer warranty, which is a reasonable signal of how the brand stands behind it.
Hizsoaor Replacement Solo 4: Who It's For
The Hizsoaor Replacement Solo 4 is a different kind of product entirely. It's a 4.6 ft (1.4 m) replacement audio cable with dual 3.5mm plugs — a straight TRS plug on one end and an "L"-shaped TRRS plug for the device on the other — finished in grey and built with OFC copper wire wrapped in a flexible TPU coating. The stated goals are high-fidelity signal transfer with minimal interference, plus tangle resistance and durability. Gold-plated connectors are part of the design, which is a common choice for corrosion resistance and consistent contact.
The reason you'd buy this is simple: your current cable is damaged or lost, and you don't want to replace the whole headphone. It's positioned as a premium replacement compatible with Beats Solo 4, and it also lists compatibility with Beats Studio, Pro, Executive, Mixr, Solo HD, Solo 3 Wireless, Solo2, Studio 2.0, and Sony noise-canceling headphones. If you own one of those, this cable is the cheapest way to get back to listening — and it adds something the original may not have had: an inline mic and remote.
That inline remote gives you hands-free calls, play/pause and volume control, and the built-in second-generation microphone is described as high-sensitivity for clear voice pickup in calls, gaming and video chats. Voice assistant support is listed too, so Siri commands work on compatible iPhones. The "L" shaped device plug is a thoughtful detail — it reduces strain on the port, which is exactly the kind of stress that kills straight cables over time.
Side-by-Side: Which Should You Choose?
• Best for a complete, ready-to-use work headset → NUBWO HW02. It has the mic, the boom, the controls and the connections built in.
• Best for reviving a pair of Beats you already own → Hizsoaor Replacement Solo 4. It solves the cable problem without buying new headphones.
• Best for mixed device setups (USB-C plus 3.5mm) → NUBWO HW02. The dual-connection design covers laptops, phones and tablets.
• Best for iPhone-based voice and Siri use (with compatible headphones) → Hizsoaor Replacement Solo 4. The inline remote and 2nd-gen mic are the selling point — as long as you're on a supported iPhone.
• Best for long calls and meetings → NUBWO HW02. Lightweight on-ear build, soft cushions, in-line volume and stated compatibility with major communication software.
• Best for music-first listening → neither is a true hi-fi pick. The HW02 is voice-tuned with a 27 mm driver, and the Solo 4 cable only improves the headphones you already have.
• Best if you're on Android or Samsung and need a working remote → NUBWO HW02. The Hizsoaor remote functions aren't supported there.
• Best if your only problem is a broken cable → Hizsoaor Replacement Solo 4. You're fixing one part, not replacing the whole setup.
If I had to pick one, I'd buy the NUBWO HW02 for most people reading this. It's a finished product: plug it in over USB or 3.5mm, put it on, and you're on a call. Nothing else is required, and the 2-year manufacturer warranty backs it up. The Hizsoaor Replacement Solo 4 is excellent at exactly one job — replacing a damaged cable on compatible Beats or similar headphones while adding mic and remote functions — but if you don't already own those headphones, it solves nothing for you. In my opinion, buy the Hizsoaor cable only if you're repairing a headphone you love; otherwise the HW02 is the safer, more complete purchase. Either way, check the current price on Amazon before deciding.
FAQ
The inline remote and mic are not supported on Samsung or Android devices according to the product details. It's aimed at older iPhones (3GS through 6 Plus), iPads and iPods; iPhone 7 and newer need the original adapter for the connection.
It plays music — 20 Hz to 20,000 Hz, 32 ohm, 98 dB — but it's tuned for voice, with a 27 mm driver and no noise cancellation. It's a work headset first, a casual listening headphone second.
The Hizsoaor Replacement Solo 4 is designed for exactly that. It's compatible with Solo 4, Solo 3 Wireless, Solo2, Solo HD, Studio 2.0 and more, with an inline mic and remote. Just confirm your model is on the compatibility list.
