Discover D904 Convertible DECT Wireless Office Headset System with Unlimited Talk Time for Professionals- Works with PC/Mac and Desk Phone- 3 Year Warranty

I have had an excellent experience with this headset so far. It's not your average plug-and-play device, it caters to someone a bit more savvy with more advanced needs but rewards you with advanced flexibility like hot swapping a battery without losing the call. That is a very cool functionality.First impressions are a bit overwhelming. There's a lot of stuff in the box and the manual is online only. I really like that - the last thing I need is more paper, just let me lookup the manual online. Points for that.Plugging the USB into my Windows10 computer it was detected and added correctly as an audio device first try. No reboot needed, so that couldn't have been easier. And they included a USB cable, which is not always the case. Nice!I didn't do any advanced connecting with a deskphone or lifter but this headset is ready for that if you need that flexibility. Like I said, this is an advanced headset, that can also just be used for more simple needs.The hardest part was manually attaching the earpiece to the headset. It takes a bit of force to snap into place and I was afraid I might break it. But all good - the build is secure and solid. It also comes with the option of a headset or ear coil so that's a nice touch. Choose which you like. The headset is very comfortable, as the device is super light. I hardly noticed I was wearing it for hours, which is a plus.Sound quality is absolutely finefor calls and meetings. Obviously it's not meant for music or video playback - it works, but that's just not what it's meant for. Voices are clear and the people on the other end could hear me loud and clear.Overall an excellent headset with advanced functionality for the more picky user.

I've had experience with single device, multi device and dual device headset/base combos - this fits nicely in that dual-device category.It does not have bluetooth connectivity, but that is clear from the item description - and quite frankly, the wired connection gives much more confidence.I found set up really simple - included card in packaging and direction to website to get more info easy to follow. I dont have a headset lifter, but I've had them in the past and know that can sometimes be finicky, and would assume similar here.Immediately connected to my computer USB hub (working from home) and my voip handset. Didn't have to adjust anything. The switching button doesn't have a fully satisfying "click" but thats my personal nitpicking.I use the over the ear set up, and per the picture attached, I am 5'8" average build male and you can see the boom for the mic comes perfectly to the edge of my mouth.Did some test calls with my wife and then some work colleagues - no one could tell any degrading quality on either MS Teams or via the voip connection.Teams - did not find that the mute functions on the headset interacted with Teams mute icons, as some headsets do. But that's OK.Battery- I *LOVE* that there is an included hot-swap battery pack that charges right there - even has a satisfying "lock" into the base while charging. Indicator lights for charging capacity right on the base unit... very helpful. The only issue there is that I'm working in my bedroom, so at night, had to cover the base, but that's a WFH issue.Battery life - found that I could go about 2/3 of the day on one battery - this was not constant calls, but mainly left the headset on my head, not in the cradle, and that was about 4 Teams meetings and various phone calls between 5-20 minutes throughout... I'd assume if you were on constant virtual meetings/calls , you would get about 1/2 day on the battery.Form factor - i took a picture of the headset with the over head attachment charging - it solidly "clicks" into the holder and therefore doesn't tip the base at all... the base is very light , which is nice , and its small, so doesn't take up a lot of room.Overall, solid dual-device wired base (wireless headset, of course) - easy set up, thoughtful design (battery swapping), simple design.

I was sent this headset to provide a review. I am a solutions engineer for a UCaaS provider and I appreciate Discover sending this to me to test prior to recommending it to customers.The headset is light and comfortable. I have a bulky, 2 ear book headset, and never use it because it's too heavy. The Discover headset was barely noticeable.The sound quality was great. I only used it for some online meeting and a few soft phone calls, but all were crystal clear. I did not have a hook switch cable to connect it to my Polycom desk phone, but I have no doubt the quality would be the same.Lastly, the range of DECT is awesome. With my regular Bluetooth earbuds, I lose signal if I stray too far from my home office. The Discover headset allowed me to roam my entire house without loss of audio.The Discover D904 headset is a great choice for a high quality, wireless audio experience, and I will be recommending these to my customers.
