How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want one ready-to-use headset for a single workstation, choose CALIDAKA USB Headset; if you need to put two people on one call at the same time for training, choose Weatwo Training Y Splitter. These two products look like they belong on the same shelf, but they solve completely different problems in a call center. One is a complete headset you plug straight into a computer. The other is not a headset at all — it is the splitter cable that lets a trainer and a trainee share one conversation. If you mix them up, you will end up with the wrong tool for the job.
• CALIDAKA USB Headset — biggest strength: a complete, plug-and-play USB headset with a noise-reduction mic, adjustable headband and inline volume/mute controls, aimed at people who take call after call all day.
• CALIDAKA USB Headset — biggest trade-off: it is a single-user headset wired permanently to USB. There is no way to share the audio with a second person.
• Weatwo Training Y Splitter — biggest strength: it lets two Plantronics quick-disconnect headsets connect to one device so both users hear and speak on the same call — exactly what real-time coaching needs.
• Weatwo Training Y Splitter — biggest trade-off: it is only a cable. You must already own two compatible QD headsets and the right connecting adapter, and it will not work with Jabra GN, Yealink, MAIRDI or Sennheiser EPOS headsets.
• Who each pick is for: CALIDAKA for an individual agent or anyone on back-to-back calls; Weatwo for a supervisor, trainer or team lead who needs to listen in and coach on the same line.
The CALIDAKA USB Headset is built around one clear idea: a single person, sitting at a computer, taking a lot of calls. That shows up everywhere in the design. The microphone has built-in noise reduction to pick up your voice clearly, and the boom is flexible so you can bend it into the right spot in front of your mouth. Small detail, but it matters when you are talking for hours — a mic that sits where you left it keeps your voice consistent from the first call to the last.
Comfort is handled with an adjustable headband on a super-lightweight frame, and the item weight is listed at just 0.08 kg. That is the kind of number that tells you this is a headset you can forget you are wearing, which is exactly what you want on a long shift. The earpieces are on-ear, and the materials are ABS and PVC — practical, hard-wearing plastics rather than anything plush. The speaker side uses a 30 mm driver at 32 ohm impedance with a frequency range of 20 Hz to 100 kHz, and the cable runs about 2 meters, which is generous enough to stand up or reach across a desk without yanking the plug out.
The controls are the part I like most for call work. Volume and mute sit right on the cord, so you can drop your level or kill the mic in a second without hunting through software. That is the difference between a smooth call and an awkward "sorry, can you repeat that." It connects over USB and is genuinely plug-and-play — no software install — so it works on a work laptop, a home PC, or a shared machine without a setup ritual. CALIDAKA lists it for online courses, Skype chat, call center, conference calls and webinars, and I would add plain office work and customer service to that list.
Who should buy it? Individual agents, remote workers, students on video classes, and anyone who lives in voice chat. Who should skip it? Anyone who needs to get a second person onto the same call. This headset is a solo tool by design, and no amount of bending the boom will change that.
The Weatwo Training Y Splitter is a different kind of product entirely, and it is important to understand that before you buy. It is a 129 cm (about 4.2 ft) adapter cable, not a headset. Its whole purpose is to take one audio source and feed it to two Plantronics quick-disconnect headsets at once, so both people can listen and talk on the same conversation. If you have ever tried to train a new hire by hovering over their shoulder and guessing at what the customer said, this is the cable that fixes that.
Compatibility is the make-or-break here, so read this part carefully. Weatwo states it works with all Plantronics QD headsets, naming the H251, H251N, H261, H261N, HW291N, HW301N, HW710 and HW720, plus all H-series and HW-series models and same-style QD headsets from TruVoice, VoiceJoy, Wantek and Daily. It explicitly does not work with Jabra GN, Yealink, MAIRDI or Sennheiser EPOS headsets. If your existing headset is one of those, this cable is simply the wrong part, no matter how good the idea is.
Setup is straightforward once you have the right pieces. You connect two Plantronics headsets and your computer (via a USB QD adapter) or a telephone (via a Plantronics QD Polaris cable) into the splitter. From there, both users share the line. That is the real value: a supervisor can listen in live and coach in real time, which is far more useful than reviewing a recording after the fact. The build is aimed at surviving that daily wear — durable PU material over flexible cable, protecting the copper conductors inside and adding toughness for a longer lifespan. It is a lightweight, black, male-to-male cable with three pins and a QD connector.
Who should buy it? Call center supervisors, trainers, QA staff and team leads who run live coaching sessions, plus anyone doing side-by-side training where two people need to hear and speak on one call. Who should skip it? Anyone who just needs a headset for themselves, and anyone whose headsets are not Plantronics-style QD. Remember you also need two compatible headsets and a QD connecting adapter to make this work — the splitter alone does nothing.
• Best for a single agent taking back-to-back calls → CALIDAKA USB Headset. It is a complete, self-contained solution with mic, speakers and controls.
• Best for live one-on-one training → Weatwo Training Y Splitter. Two headsets, one conversation, real-time coaching.
• Best for plug-and-play simplicity → CALIDAKA USB Headset. USB connection, no software installation, no extra parts to buy.
• Best if you already own Plantronics QD headsets → Weatwo Training Y Splitter. It turns hardware you already have into a training station.
• Best for quick mute and volume access → CALIDAKA USB Headset. Inline cord controls you can reach without leaving the call window.
• Best for durability in a shared training room → Weatwo Training Y Splitter. PU-jacketed cable built to take repeated handling.
• Best for long-shift comfort → CALIDAKA USB Headset. Lightweight on-ear design with an adjustable headband.
• Best if you are unsure what you need → CALIDAKA USB Headset. It works out of the box for one person; the splitter only makes sense if you already have the right headsets.
For most people reading this, I would buy the CALIDAKA USB Headset. In my opinion, it is the safer, more complete purchase: one device, plug it into USB, and you are on calls with a noise-reduction mic, adjustable fit and cord controls. It covers the everyday reality of call center and office work without asking you to own anything else first.
The Weatwo Training Y Splitter is the better buy only if you are specifically running training or supervision and you already have two Plantronics QD headsets plus a connecting adapter. Buy it for that job and it does something no ordinary headset can. Buy it expecting a headset and you will be disappointed.
Yes — that is exactly the use case it is designed around. It has a noise-reduction mic on a flexible boom, inline volume and mute controls, and a lightweight adjustable fit for long shifts. It connects over USB with no software install.
No. It is made for Plantronics quick-disconnect headsets and same-style QD models from brands like TruVoice, VoiceJoy, Wantek and Daily. It does not work with Jabra GN, Yealink, MAIRDI or Sennheiser EPOS headsets.
Yes. You need two compatible Plantronics QD headsets and one QD connecting adapter — a USB QD adapter for a computer, or a Plantronics QD Polaris cable for a phone. The splitter alone will not connect anything.
That depends on the job, so it is worth checking the current price on Amazon for both. If you need one working headset, the CALIDAKA is the more complete purchase. If you need to train two people on one call and already own the right headsets, the Weatwo splitter is the more useful tool.
