How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a pair of true wireless earbuds for music, running and everyday phone use, choose Ordtop Earbuds; if you need a wired USB headset for clear calls, meetings and all-day desk work, choose Callez USB Headset. These two products look like they belong in the same conversation because both have microphones and both are sold as "headsets," but that's where the overlap ends. One is a Bluetooth bud you wear in your ears and forget about; the other is a plug-in office tool built around one job — making your voice sound good on a call.
• Ordtop Earbuds — biggest strength: fully wireless Bluetooth 5.4 with up to 40 hours of total playback from the charging case and an IP7 waterproof build. Biggest trade-off: it's a consumer music bud first; there's no dedicated call-control button and no wired fallback if the battery runs out.
• Callez USB Headset — biggest strength: dual-mic ENC noise cancelling with a built-in A8 algorithm chip, plus a one-touch Microsoft Teams call button and mic mute. Biggest trade-off: it's wired USB-A only, so it's tethered to a computer and useless on a phone or in the gym.
• Who Ordtop is for: commuters, runners, gym-goers and anyone who wants music and casual calls without cables.
• Who Callez is for: office workers, call centre agents, remote staff and students who live in Teams, Zoom or Skype all day.
The Ordtop Earbuds (model i63) are built around convenience and battery life. The headline spec is Bluetooth 5.4 with the HSP, HFP, A2DP and AVRCP profiles, a claimed 0.1-second low latency mode and a 15-metre wireless range. In plain terms: pairing is quick and the connection should hold up when you set your phone down and walk to the other side of the room. The low-latency mode matters if you watch video or play games, where audio lag is the thing that ruins the experience.
Sound is handled by a 13mm dynamic driver with what Ordtop describes as DSR lossless HD rendering. A 13mm driver is a genuinely large unit for an in-ear bud, and the design brief is clearly bass-forward — punchy low end, full midrange, crisp treble. Four microphones plus ENC noise cancelling handle calls, so your voice should come through reasonably clean when you're talking on a busy street. There's also active noise cancellation on board, controlled by touch sensors that also handle play/pause, track skipping, volume and voice assistant activation.
Who should buy it: anyone who wants one pair of buds for the gym, the commute and casual calls. The IP7 rating and secure fit make it a natural sport companion, and the 40-hour case means you can leave the charger at home for a week.
Who should skip it: if your job is back-to-back video meetings, this isn't the tool. There's no boom mic, no hardware mute button and no Teams integration — and because it's Bluetooth only, you're relying on battery for every call.
Callez USB Headset: Who It's For
The Callez USB Headset (model GC700TA2) is the opposite philosophy: it does fewer things, but it does the call-centre thing properly. The core feature is dual-microphone ENC noise cancelling. One mic picks up your voice, the second samples the room, and a dedicated noise-cancelling chip running what Callez calls A8 algorithm technology strips out the background noise in between. That's a meaningfully different approach from a single mic with software processing — the goal is to preserve your voice while killing the hum of an office, a fan or a busy household.
Then there's the control scheme, which is where this headset earns its place. A single press of the call button answers, ends or cancels Microsoft Teams calls, and it can also open Teams or join a meeting. There's a mic mute and volume control built into the inline controller, plus a visual busylight that signals to people around you that you're on a call. Callez notes that the call button works with Teams and Skype for Business built on Teams; with Zoom you can answer from the button but need to click to hang up in the software. That's an honest limitation worth knowing before you buy.
Comfort is the other half of the pitch. The headset weighs only 2 oz, which is genuinely light for an on-ear design, and the 6.56 ft (2 m) cable gives you room to lean back or stand up without unplugging. The headband is adjustable, the earcup is wrapped in skin-friendly memory foam with a leather finish, and it's a mono design — one earcup, one ear free to hear the room. Impedance is 32 ohm, which is an easy load for any laptop or desktop to drive.
Connection is USB-A wired, and there's no Bluetooth at all. That's a feature, not a flaw, in an office context: no pairing, no charging, no dropouts, no battery anxiety. You plug it in, and it works. Callez also backs it with a 45-day money-back window and a 24-month warranty, and the package includes the headset, inline controls, adjustable headband and soft earcushion.
Who should skip it: if you want to listen to music on the train, take calls from your phone, or move around the house while talking, this is the wrong product. It's tethered, it's mono, and it's USB-A only.
Side-by-Side: Which Should You Choose?
• Best for all-day music and battery life → Ordtop Earbuds. 8 hours per charge and up to 40 hours with the case is a different league from a wired headset you can't leave your desk with.
• Best for voice quality on calls → Callez USB Headset. Dual-mic ENC with a dedicated noise-cancelling chip and A8 algorithm is built specifically to isolate your voice from background noise.
• Best for workouts and weather → Ordtop Earbuds. IP7 waterproofing plus a curved, ear-canal-shaped fit is designed for sweat, rain and movement.
• Best for meeting controls → Callez USB Headset. One-touch Teams answer/end, mic mute, volume and a busylight — no software hunting mid-call.
• Best for travel and commuting → Ordtop Earbuds. A pocket-sized case with a dual LED display and USB-C charging is made to leave the house with you.
• Best for zero-maintenance reliability → Callez USB Headset. Wired USB-A means no pairing, no charging and no connection drops during a presentation.
• Best for phone and tablet use → Ordtop Earbuds. Bluetooth 5.4 covers Android, iOS, laptops and TVs over a 15-metre range. The Callez headset has no wireless technology at all.
• Best for long desk sessions → Callez USB Headset. At 2 oz with memory foam and a 2 m cable, it's designed to be worn for a full working day.
If I had to pick one, I'd buy the Callez USB Headset — but only because of the job it's built for. If your day is calls and meetings, the dual-mic ENC array, the one-touch Teams button, the hardware mute and the busylight solve real problems that a pair of music buds simply doesn't address, and the wired USB-A connection removes every variable that can ruin a client call.
That said, I'd recommend the Ordtop Earbuds without hesitation to anyone who wants one pair for music, running and casual calls. It's the more versatile product by a wide margin — Bluetooth 5.4, 40 hours of case-backed playback, IP7 waterproofing and a 13mm driver are a genuinely strong combination for everyday life. These aren't competitors so much as two tools for two different rooms. Check the current price on Amazon for whichever one matches your day, since that's the only variable I can't weigh for you.
For occasional calls, the Ordtop's four microphones and ENC noise cancelling are fine. For anything where call quality is critical — client calls, interviews, hours of meetings — the Callez dual-mic ENC design with its A8 algorithm chip and hardware mute is the more appropriate tool.
No. It connects over a USB-A plug and has no wireless technology, so it's designed for PCs, laptops and docking stations. If you need something that works across Android, iOS and computers, the Ordtop Earbuds are the right choice.
The Ordtop Earbuds, by default — 8 hours per charge and up to 40 hours total with the charging case. The Callez USB Headset draws power over its USB cable, so it has no battery to run down, but it also can't leave the desk.
Yes. They carry an IP7 waterproof rating, which covers sweat, rain and splashes, and the curved shell is shaped to match the ear canal so they stay in place during movement. The Callez headset has no water-resistance rating and is intended for indoor desk use.
