Do you want the best headset? 
Are you looking for the best wireless office phone headset?
Meet Discover D904
Discover D904 is one of the most comfortable wireless headsets as its convertible and can be worn over the ear or over-the-head. It's versatile as it can connect to your office phone and computers with DECT 6.0 wireless technology giving you 10x the wireless freedom as Bluetooth headsets. Top that off with UNLIMITED talk-time, so you always have a headset and never have to worry about running out of battery life.
In this blog, we cover all the details, including a microphone sound test so you can hear the quality and noise-cancelling technology for yourself.
Let's get started!
Comfort
Wearing style - Convertible
The Discover D904 wireless office phone headset includes 3 ear loops and 1 headband giving you the ability to find a fit that is comfortable for you.
The headband is adjustable as everyone has different size head. Finding that perfect fit is easy. The headband also has a soft leatherette ear cushion that makes the earpiece feel like a cloud resting on your ear.
Headset Weight - 0.9oz
The headset's weight is surprisingly light as many of the headset options out there can weigh 10oz plus, meaning it's 90% lighter than some headset options.
Searching for a wireless office phone headset probably means you or your employees are quite a bit on the office phone.
On the phone a lot?
In my opinion, you MUST have a headset that is comfortable for all-day use. Since the D904 weighs less than an ounce, you'll find that when wearing the earpiece over-the-ear or over-the-head, it won't cause discomfort when wearing for a full 8-hour shift like other headsets on the market.
Earpiece Style - On Ear
When wearing the earpiece with the included ear loops, you'll notice that the speaker rests on top of the ear. The speaker does not go in the ear canal as apple earbuds do. Some customers tell us they prefer not to have something go inside the ear. The D904 will rest on top of the ear.
Sound Quality
Speaker Sound Quality - Good
The speaker size allows the headset's volume to be loud enough to hear callers clearly, even if there is some noise around you. Other models have better sound, but those headset's size and weight are up to 10 times more, leaving them not comfortable for a long time.
When listening to meetings, callers, or music, the sound quality is good enough to be enjoyable, but you'll be disappointed with the bass and range of sound if you are an audiophile. If you want the best audio quality for music, check out the Bose 700 UC here. However, most of us working professionals would rather have a headset comfortable for all-day use that still has a good sound, which the Discover D904 has.
Professional Noise Cancelling Microphone - Yes
Having your customer say something like...
Can you hear me now?
or
Please repeat what you said, I can't hear you.
Low microphone sound leads to both you and the caller being frustrated and increases stress on everyone. The simple fix is having a professional-grade noise cancelling microphone. The Discover D904 has a powerful microphone that allows your voice to be heard clearly, as pictured below.
Wireless Office Phone Headset Microphone TEST
In the video below, we do a full noise cancelling microphone test to hear for yourself how well the sound quality is. We plugged the office phone headset directly into the computer and recorded the sound without modification.
Check it out in the video below.
Want even more noise cancelling?
We recently did an in-depth review of a software application that you can download onto your computer that uses artificial intelligence to remove most unwanted background noise for both your microphone and speaker.

Connectivity - Desk phone & Computer
Office phone
If your office uses corded office phones, either VOIP or analog, from brands such as Yealink, Avaya, Cisco, Polycom, Grandstream, and more, this Discover D904 is 100% compatible with your office phone.
Included in the box is an RJ9 connector cable that plugs directly into the back of your office phone. Connecting the headset to the office phone gives you the ability to be entirely wireless for up to 300 feet away from the phone.
Not using a headset can lead to what the great Shaq calls the taco neck syndrome.
A simple cure is to buy a wireless office phone headset.
All jokes aside, adding a wireless headset to your office phone is a simple solution to be more productive, cause less strain on your neck, and reduce stress.
Computer
The Discover D904 connects to your office phone, but it also connects to your computer via USB. Many business communication software now runs directly through the computer requiring a headset even to use it.
How does it work?
Plug the USB cable into the computer.
Press the computer button on the charging base.
Take your Zoom meetings, business calls, or your music with you wirelessly up to 300 feet away with full professional sound.
Stuck on a Zoom meeting but need coffee?
No worries, you have the freedom to do so with the Discover D904.
Will it work on your software?
Yes, it will work with any of your software such as RingCentral, YouTube, Google Meet, Zoom, Jabber, BlueJeans, and any other software on your computer.
Wireless Technology - DECT 6.0
The Discover D904 uses a highly efficient DECT 6.0 wireless chipset to give you a secure wireless range of up to 350 feet of wireless range.
What I like about DECT 6.0 is that it provides a wireless range of up to 10x that of most Bluetooth headsets, so you'll be able to roam around your house and office and not be trapped nearby your desk.

Battery life - UNLIMITED
Have you ever left your wireless headset on your desk without plugging it into the charger?
DOH!
Sadly, that's happened to me more than on a few occasions. That happened to me just today, leaving me with only 1 hour of battery life when I started the day.
It leaves me to sit and wait hours before I can utilize my headset again.
Fortunately.
With the Discover D904 it has a secondary battery in a slot on the charging base. So if that unfortunate situation happens, you can swap out the battery and never have a dead headset.
If you are a phone warrior and are on the phone for longer than 6+ hours straight, what you'll find is that your headset battery will die before the end of the day. With this wireless office headset, you'll never worry about your battery dying again!
