When looking to buy headsets for yourself or your company, you’ve undoubtedly come across Bluetooth headsets and DECT headsets. The terms Bluetooth headsets and wireless headsets are often used interchangeably, and the lines between Bluetooth and DECT can often seem a bit blurry. But they are basically the same thing, right? Well, not really. Both have uniquely different technologies, and the one that is right for you depends on what your specific needs are.

If that’s still as clear as mud, read on, and in the next couple of minutes, you’ll have a clear understanding of the difference between the two and, more importantly, which ones will suit you or your staff members.

DECT vs Bluetooth Headsets: Which Is Right For You?

To work out which is right for you, you’ll first need to evaluate how you are going to use your headsets. If you’re working in an office, you’ll want little interference and as much range as possible to move around the office or building without fear of being disconnected. Are you using a desk phone with Bluetooth? Then headset compatibility may be an issue for you, and you’ll need to look for the kind of headsets that are optimised for desk phones. Does your job require you to be on the road? If it does, you will need a portable headset that can connect to a range of other devices, including your smartphone, laptop and tablet.

But what is DECT technology anyway? What is a DECT headset? And what's the best choice between Bluetooth headsets vs DECT headsets? So many questions… Let’s delve into the details a bit more. We’ll try to answer your questions, while comparing the features of Bluetooth vs DECT.

DECT vs Bluetooth Headsets Feature Comparison

Feature DECT Bluetooth
Radio frequency 1.9 GHz 2.4 GHz
Voice quality Desk phone quality Mobile phone quality
Use with Wi-Fi Excellent Limited
Use with mobile phones No Yes
Range Up to 350 feet Up to 30 feet (Class 2) Up to 330 feet (Class 1)
User density Up to 1 per cubicle 8 active users per 3000 sq. ft.
Talk time Excellent Excellent
Security Excellent Excellent
  • Connectivity. DECT headsets can only connect to a base station which provides the headsets with an internet connection. This offers limited connectivity but is perfect for a busy office environment where the user doesn’t have to leave the building while wearing them.

Bluetooth headsets can connect with up to eight other devices, making them a better option if you need to be on the move. Bluetooth headsets also offers you the flexibility of working through your PC, tablet, or phone.

  • Security. DECT headsets operate on 64 bit encryption and Bluetooth headsets on 128 encryption and they both offer high protection. The chances of anyone eavesdropping on your call are virtually non-existent for both. Although, DECT headsets do provide an extra level of security that may be required for people in legal or medical settings.

Realistically though, there is very little to worry about with security for either Bluetooth headsets or DECT headsets

  • Wireless Range. There’s no contest with wireless range. DECT headsets have a far greater range of 100 to 180 metres because it’s designed to connect to its base station and allow movement within its range without fear of losing connection.

The Bluetooth headset range is around 10 to 30 metres, significantly less than DECT headsets because Bluetooth headsets are portable and are designed to connect to many different devices. Realistically though, If you’re connected to your phone or tablet, you probably won’t need to be more than 30 metres away from them.

  • Compatibility. Most Bluetooth headsets aren’t compatible with desk phones. If you want to connect to a desk phone, then a DECT headset will work for you as they are optimised for that purpose. Bluetooth headsets are compatible with ANY Bluetooth enabled device, and can connect to them automatically.

DECT headsets are reliant on their base station, and they have limited options to what they can pair with. They can connect to a DECT phone with Bluetooth and will still pair with your PC, but It’s slightly more complicated to do. The base station will need to be connected to your computer's USB, and you’ll have to select your headset as the default playback on your PC.

  • Battery. Both commonly have batteries that can’t be replaced. Most of the early Bluetooth headset models had batteries that only allowed for talk times of 4-5 hours, but today, it’s not uncommon to get 25 or more hours of talk time.

DECT commonly gets you around 10 hours of battery life depending on the headset you buy, which means that you’ll rarely run out of charge.

  • Density. When there are many headsets in an office environment or a call centre, a Bluetooth headset is much more likely to give you more interference as the headsets are competing with other Bluetooth devices on the same crowded frequency. Bluetooth headsets are designed for single-person use and are better suited to smaller offices or for people who are working from home.

DECT will be a better fit for you if you’re working in a crowded office or call centre environment as it doesn’t have the same density issues and supports much higher user densities.

  • Sound Quality. When it comes to DECT headset vs Bluetooth headset sound quality, it largely boils down to which format is affected by crowding on the same frequency.

Bluetooth is prone to interference, particularly when other headsets close by can cause density issues as Bluetooth transmits data and audio, giving a range of devices more opportunities to interfere with the audio signal.  DECT has incredibly high sound quality and better stability because it is specifically designed to transmit just audio.

How to Choose Between DECT or Bluetooth Headsets

Your choice hinges on how you are going to use your headsets. If you’re working in a call centre and work at your desk most of the time, then maybe a DECT headset is for you. But if there are only a couple of other people in the office with you during office hours, Bluetooth headsets could work also.  If you need to use your headset to connect with your mobile phone, a Bluetooth headset will be better. Just keep the density limits in mind. If you’re working in a space with more than ten others, and they’re all using Bluetooth technology, you may have some interference and audio issues.

There are no ‘winners’ in the comparisons between DECT headsets and Bluetooth headsets. Either one (or both) might be right for you or your business depending on your circumstances.

For office or call-centre workers – go for DECT headsets.

For Hybrid or those of you who are on the road or out of the office a lot – Choose Bluetooth headsets.
