DECT vs Bluetooth Headset for the Office: Singapore Guide

DECT or Bluetooth is the first decision in any office wireless headset purchase, and the short answer is this: choose a DECT headset when the user sits at a desk with a desk phone, needs to walk 100 m or more from the base, or works on a floor where dozens of colleagues wear headsets at once; choose a Bluetooth headset when the user works from a laptop and a mobile phone, moves between office, home and client sites, and wants one headset for all three. This guide explains the trade-offs in range, user density per floor, audio latency, Microsoft Teams certification, desk-phone control through EHS versus softphone control, battery life and security, using the Yealink WH-series DECT headsets (Yealink WH63 E2, Yealink WH64, Yealink WH68 Hybrid) and the Yealink BH-series Bluetooth headsets (Yealink BH70 MS, Yealink BH74 MS, Yealink BH78 MS) that SourceIT supplies in Singapore as the worked examples. It sits under our Yealink Singapore buyer's guide; the model-by-model detail is in the WH63 vs WH64 vs WH68 DECT comparison and the BH70, BH71, BH74 and BH78 Bluetooth comparison.

How far can you walk from your desk: DECT range vs Bluetooth range

DECT wins on range by a wide margin. Yealink rates the Yealink WH63 E2 at up to 120 m from its base, the Yealink WH68 Hybrid at up to 150 m in DECT mode, and the Yealink WH64 and WH68 Stereo at up to 185 m. Those are open-air figures; Yealink notes that walls shorten them, but in practice a DECT user can walk to the pantry, the printer room or a colleague's desk on the same floor without the call dropping. Every Yealink BH-series headset is rated at up to 50 m over Bluetooth 5.3, enough to stand up and pace around a meeting room, not enough to leave the zone. If the role involves fetching files, checking stock or walking a shop floor while on a call, that alone decides it: DECT.

How many wireless headsets can one floor support?

This is the question that catches out open-plan offices and contact centres. DECT uses its own licensed band (1880 to 1900 MHz in Yealink's European spec; Singapore uses the same DECT allocation) that no Wi-Fi access point, mouse or keyboard shares, and the system is engineered for density: Yealink's WH63 page states support for up to 200 users in the same area in Europe. Bluetooth headsets operate in the 2.4 GHz band alongside Wi-Fi, wireless mice, keyboards and every mobile phone in the room. A handful of Bluetooth headsets spread across a floor work well; thirty in adjacent rows of a customer-service team start to compete for airtime and the symptoms are dropouts and robotic audio. What we see in Singapore deployments is that teams of more than about ten adjacent headset users on continuous calls are quoted DECT, while hybrid-working knowledge workers who are at their desk two or three days a week are quoted Bluetooth.

Latency follows the same logic. DECT carries voice on a dedicated channel between the headset and its base with a fixed, low delay, which is why call-centre agents rarely notice any lag between speaking and hearing their own sidetone. Bluetooth adds the codec and the host's own Bluetooth stack to the path; for conversation it is not a problem, and the BT51 dongle avoids the worst of a laptop's built-in Bluetooth behaviour, but on a crowded 2.4 GHz floor the retransmissions that keep the link alive are what you hear as delay. Both families use multi-microphone noise cancelling: the WH64 and WH68 carry three- and four-microphone arrays, the BH70 three beamforming microphones, and the BH74, BH78 and WH68 add four-mic hybrid active noise cancellation that cuts the room noise reaching the wearer.

Does a DECT or Bluetooth headset work with Microsoft Teams?

Both can, and certification is per model, not per technology. On the DECT side the WH63 E2 is certified for Microsoft Teams with a dedicated Teams button, and the WH64 and WH68 are sold as a Teams-certified variant and a UC variant; the Teams SKUs are the ones in our catalogue (for example the WH68 Hybrid Teams at S$226.12 and the WH68 Hybrid UC with charging stand at S$241.31 for non-Teams platforms). On the Bluetooth side the Yealink BH74 MS is certified for native Bluetooth Microsoft Teams and its four-mic noise cancellation meets the Microsoft Teams Premium Open Office standard, while the BH70 MS and BH78 MS are the Teams-edition SKUs of their families. The practical difference: a Teams-certified headset shows a Teams button that raises the client, answers and mutes from the headset, and reports presence to the busylight. Buy the MS or Teams SKU if the organisation is on Teams and the UC SKU for Zoom, Webex, Google Meet or a SIP softphone.

Desk phone control (EHS) vs softphone control

If the user still answers a Yealink, Cisco, Poly or Avaya desk phone, DECT is the native fit because the base connects to the phone as well as the PC and the headset controls both. Yealink's WH63 page sets out the rules: Yealink IP phones connect to the base with a single USB cable and need no EHS adapter; Yealink T3-series phones need the EHS35; Cisco, Poly and Avaya phones use the EHS60; Mitel and Unify phones use the EHS61; and the WH64 and WH68 add the optional EHS62 telephone cable for multi-brand phones. The headset can be connected to a PC and a desk phone at the same time, and the user answers either from the earpiece. Our catalogue lists the Yealink EHS60 adapter at S$45.00 and the Yealink EHS62 at S$55.00, both available to order. A Bluetooth headset is built around the softphone: Teams, Zoom or a SIP client on the laptop, plus the mobile as the second connection. It can pair to a desk phone that has Bluetooth, but you lose the base-driven remote answer that DECT gives. If the office has already moved to Teams Phone on the PC and the desk phone is gone, that is a point for Bluetooth; the Yealink Microsoft Teams phones collection shows the desk phones that still make sense alongside either.

Battery life, charging and security

Bluetooth headsets generally last longer between charges because they do not maintain a base link: Yealink rates the BH70 MS at up to 35 hours of talk time with the busylight off, the BH74 MS at up to 32 hours and the BH78 MS at up to 38 hours with ANC and busylight off, with 90 to 130 minute charges. The DECT models are shorter but sit on a charging base all day: the WH63 E2 up to 8 hours, the WH64 14 hours mono or 16 hours dual, and the WH68 family 16 hours in DECT mode, rising to 32 hours when the WH68 Hybrid switches to Bluetooth. For a desk-bound agent, 8 to 16 hours with the base as the charger is a full shift; for a hybrid worker who forgets the cable, the 30-plus-hour Bluetooth models are safer, and the BH74 MS with stand at S$197.10 or the BH70/WH64 charging stand at S$25.00 adds a drop-on charger to the desk.

On security, both technologies encrypt the link, and the difference is more about exposure than strength. A DECT headset only ever talks to its own base, on spectrum that no visitor's laptop or phone scans, and Yealink's WH68 family is rated Secure DECT Step C, the current DECT security level. A Bluetooth headset is discoverable during pairing and stores up to 8 paired devices, so IT needs a policy on which laptops and personal phones may be paired; the BT51 dongle helps because the headset pairs to the dongle, which the organisation owns, rather than to whatever laptop Bluetooth is nearby. For government and regulated finance buyers in Singapore who ask us about headset security, DECT is usually the simpler answer to document.

Which to choose: DECT or Bluetooth headset

If budget rules and the user never leaves the desk, a wired USB headset is cheaper than either; our ultimate guide to Yealink headsets covers the UH-series alongside WH and BH, and the Yealink headset price list has every current SKU in one table.
