• TREBLAB X3-Pro — biggest strength: a genuinely wireless, ear-hook sport design with a huge battery story (up to 12 hours per charge, up to 192 hours total with the case) plus 4 ENC mics for calls on the go.
• TREBLAB X3-Pro — biggest trade-off: it's an in-ear hook design, so if you want a headband-style headset you can leave on your head all day at a desk, that's not what this is.
• Callez USB Headset — biggest strength: plug-and-play USB-A connectivity with dual ENC mics, a flexible 350° boom mic, an MS Teams call button and in-line mute/volume controls for meeting-heavy workdays.
• Callez USB Headset — biggest trade-off: it's wired, so you're tethered to your computer by a 6.56 ft cable — no walking around the house mid-call.
• Who each pick is for: the TREBLAB X3-Pro suits runners, gym-goers and people who take calls away from a desk; the Callez USB Headset suits home-office workers, call-center staff and anyone living in Teams or Zoom.
The X3-Pro is a sport-first wireless earbud, and the specs back that up. The ear-hook shape is the defining feature here — instead of relying only on an ear tip to stay put, a hook wraps over the ear so the bud holds firm during movement. TREBLAB ships five sizes of silicone ear tips to help dial in the fit, which matters a lot for both comfort and for keeping bass consistent during a run.
Battery is the other headline. You get up to 12 hours per charge, and the charging case pushes total playtime up to 192 hours. That's the kind of number that changes how you use a product — you stop thinking about charging as a daily chore. The USB-C case doubles as a power bank, so on a long trip you can top up your earbuds and, in a pinch, use that reserve for other devices.
Who should buy it: runners, gym users, travelers and anyone who wants wireless earbuds with a mic for calls and music on the move. Who should skip it: if you want a traditional over-the-head headset for eight hours of desk calls, or you specifically need a wired USB connection to a computer, this isn't the tool for that job.
Callez USB Headset: Who It's For
The Callez USB Headset is the opposite philosophy: it's a purpose-built work headset. It connects over USB-A, so there's no pairing, no charging, no battery to manage — you plug it in and it's ready. For anyone who has ever fought with Bluetooth pairing five minutes before a meeting, that simplicity is the whole point.
The audio side is built for speech. Dual ENC microphones handle noise cancellation, and the flexible boom mic rotates up to 350°, so you can position it right where your voice is loudest and background noise is quietest. The 28 mm dynamic drivers are tuned for clear, professional-sounding calls rather than thumping music, and Acoustic Shock Protection is included to guard your hearing against sudden loud spikes — a detail that matters if you spend hours a day on calls.
Controls are where this headset earns its keep in a Teams-heavy workplace. A dedicated call button lets you answer, end or cancel Microsoft Teams calls with one press, and opens the Teams window or joins meetings. In-line controls cover mic mute/unmute and volume up/down. There's also a visual busylight so people around you know you're on a call — genuinely useful in a shared office or a busy home.
Comfort is addressed with a lightweight build (about 2 oz), an adjustable headband, soft memory foam ear cushions and skin-friendly materials. The 6.56 ft cable gives you some room to lean and shift. It's also backed by a 45-day money-back window and a 24-month warranty.
Who should buy it: home-office workers, call-center agents, students in online classes and anyone who lives in Teams or Zoom on a laptop or desktop. Who should skip it: if you need to move around freely, take calls while walking, or use headphones with a phone or tablet on the go, the wired USB-A connection will feel limiting.
• Best for battery life → TREBLAB X3-Pro. Up to 12 hours per charge and up to 192 hours total with the case, with the case doubling as a power bank.
• Best for all-day desk calls → Callez USB Headset. No battery anxiety, plug-and-play USB-A, and a busylight for open offices.
• Best for running, gym and workouts → TREBLAB X3-Pro. Ear-hook security, IPX5 sweat resistance and five ear-tip sizes for fit.
• Best for Microsoft Teams workflows → Callez USB Headset. A dedicated Teams call button plus in-line mic mute and volume controls.
• Best for microphone clarity in noisy surroundings → a tie, with different strengths. The X3-Pro uses 4 ENC mics for on-the-go calls; the Callez pairs dual ENC mics with a 350° adjustable boom mic for stationary work.
• Best for wireless freedom → TREBLAB X3-Pro. Bluetooth 5.3 with roughly 33 ft of range and no cable at all.
• Best for low-latency video and gaming → TREBLAB X3-Pro. A 60 ms gaming mode is built in.
• Best for travel → TREBLAB X3-Pro. The charging case and power-bank function are made for being away from outlets.
In my opinion, these two products barely compete — they solve different problems, and the right answer depends entirely on where you'll use them. If your day is built around a laptop, Teams meetings and long stretches of talking at a desk, I'd buy the Callez USB Headset: the wired USB-A connection, boom mic and call controls are exactly what that job needs. If you want one pair of earbuds for running, the gym, commuting and calls on the move, I'd buy the TREBLAB X3-Pro for its ear-hook fit, IPX5 rating and enormous battery reserve. If you can only pick one and you split your time between both worlds, decide which happens more often — desk calls or movement — and let that break the tie.
FAQ
how to use wireless headphones mic on pc
can you use bluetooth headphones as a mic
Yes, if the headphones have a built-in microphone. The TREBLAB X3-Pro includes 4 ENC microphones, so it can act as a Bluetooth mic for calls and meetings once connected. The catch is that Bluetooth audio quality on calls depends on your computer's Bluetooth adapter and the connection stability.
do all bluetooth headphones have a microphone
No. Plenty of Bluetooth headphones are designed for listening only. The TREBLAB X3-Pro does include mics, but that's a feature of this specific model, not a guarantee across the category. If calls matter to you, check the spec sheet for a microphone before buying.
how to use mic on wireless headphones
Pair the headphones, open your computer's sound input settings, and choose the headset as the recording device. Then test the level in your call or meeting app before you rely on it. If the mic sounds distant, move closer to the earbuds or switch to a boom-style headset like the Callez for desk work.
