Range is the one spec that decides whether a DECT wireless headset actually works for your office — walk too far from the base and the call drops, no matter how good the audio is. If you're outfitting a large floor, a warehouse office, or just want to walk to the far side of the building without losing a call, range is the number to compare first. Here's how the current DECT wireless systems stack up.
Quick answer
Last updated July 2026
Why line-of-sight range isn't your real-world range
Every DECT headset's advertised range (490, 580, 590 feet) is measured line-of-sight — an open floor with nothing in the way. In a real office, walls, cubicle partitions, metal filing cabinets, and other electronics cut that significantly. A headset rated for 490 feet line-of-sight typically delivers 150–250 feet in a normal office layout. That doesn't make the spec meaningless — a higher line-of-sight rating still generally means better real-world range — but don't expect to walk the rated distance indoors.
Myth
A headset rated for 490 feet will let me walk 490 feet from my desk indoors.Reality
Not in a typical office. That figure is measured line-of-sight with nothing obstructing the signal. Walls, furniture, and other wireless devices all reduce range — a real office typically delivers 150–250 feet from a headset rated 490+ feet line-of-sight. The rating is still useful for comparing headsets against each other; just don't expect the number itself indoors.Desk phone + computer: the Jabra pick

If you only need DECT range for a computer softphone — no desk phone — Jabra's Engage 55 line uses a dedicated USB dongle (the Link 400) rather than the full desk-phone base, at a lower cost.

What is the longest-range wireless headset for a desk phone?
The current EPOS IMPACT 5000 series offers up to 590 feet of line-of-sight DECT range, the highest among current desk-phone-and-computer wireless headsets. The Poly Savi 7310/7320 reach up to 580 feet, and the Jabra Engage 65 SE reaches up to 490 feet but supports higher headset density for busy floors. Real-world office range for all three is typically 150–250 feet.
What replaced the Jabra Engage 65 and Engage 75?
Both the original Jabra Engage 65 (Stereo) and Engage 75 (Mono and Convertible) are discontinued. The Jabra Engage 65 SE is the current replacement, with USB-C charging, improved battery life, and a higher-density DECT chipset for offices running many headsets in one location.
What happened to the Sennheiser SDW wireless headsets?
Sennheiser's enterprise headset line is now sold under the EPOS brand. The SDW 5000 series (including the SDW 5015 and SDW 5066) has been succeeded by the EPOS IMPACT 5000 series, which offers the same class of range and features under the current brand name.
Is there a DECT wireless headset for a computer without a desk phone?
Yes. The Jabra Engage 55 uses a dedicated USB dongle (the Link 400) rather than a full desk-phone base, giving DECT range and FIPS 140-2 encryption for computer-only use at a lower cost than the desk-phone Engage 65 SE. It can also work as a corded USB headset if the dongle isn't available.
Why is my wireless headset's real range shorter than advertised?
Advertised DECT ranges (490–590 feet) are measured line-of-sight, with no obstructions. In a real office, walls, furniture, and other electronics reduce that significantly — typical indoor range is 150–250 feet even for headsets rated well above 490 feet. The line-of-sight rating is still useful for comparing headsets, just not as a literal indoor distance.
Range comparisons only matter in the context of your actual floor plan — a small office rarely needs 580 feet of anything, while a warehouse or large open floor benefits from every foot. Match the connection you need (desk phone, computer, or both) first, then pick the longest range within that category your budget allows.
