Great Audio, easily pairs and long battery life
Longtime Plantronics user here - I decided to try this headset as the Plantronics headsets have become so expensive. In my experience, this headset ROCKS! Noise cancelling is very effective. Battery life is so much longer than my Plantronics headsets and it has paired easily with my devices. I have a Samsung S23+ as my primary phone and an S21 for my work phone. Headset works beautifully with both of those. This doesn't have all of the bells and whistles of the Plantronics headsets, but it really shines where it counts - audio quality, noise cancelling and battery life. Not going back to Plantronics devices.

Was nice, but stopped working. [Updated]
UPDATED REVIEW>>>Happy to report that the customer service team did come through.After reaching out to them for a second time, they responded and promptly shipped me a replacement item.During the email exchange, I did see that the company attempted to contact me after my initial outreach, but for whatever reason, I was unable to locate their message (even after searching for key words in my inbox). Not sure if that was an issue with Gmail, or if the company's CRM/email platform just didn't fully execute on the email to me.At any rate, I was happy to see that they attempted to resolve my concerns in a prompt manner.As such, I've updated my rating from 1 star to 5 stars.As I mentioned in my original view, I enjoyed the product and found it to be a nice option for the work calls I took from my phone and computer.In addition to the original customer service team reaching out, a different team saw my review and reached out as well.As most people have experienced first hand, no company and no product will always be perfect. In a day and age when things can be hit-or-miss, I've come to place a greater value on the company's response and the level of customer service they provide.This company has demonstrated that they are willing to resolve issues and make things right, which is one of the reasons they have earned my business should I need new/additional devices in the future.ORIGINAL REVIEW>>>Initially I enjoyed the product, as a cost-effective option for taking work calls privately.Sadly, the product recently stopped working and no longer passes audio through the mic or earpiece.Although I wasn't excited about the item failing, I didn't get too mad because I recalled it coming with a 2-year warranty...and the product is only one year old.Unfortunately, I reached out to the seller via the support email provided in the original box and I haven't heard back about how to get a replacement device.I've now been without a working device for over a week, which makes virtual meetings very challenging when I'm in the office.I guess I'll just have to wait to see if the company will stand behind their product and warranty.Definitely wished the customer service was a bit more prompt and responsive.

noise cancelling microphone
1. The best possible noise cancelling feature.2. Connects easily.3. Holds charge very long.4. I would change warning talk to a beep sound, because until it says "your mike is now connected" you miss what they are saying on the other end.I was desperately looking for a headset with a noise-canceling microphone. This turned out to be the one. Background noise is cancelled probably by 95%. Even if I move the microphone a little up/away, they can barely hear me. This resolved many issues I had when talking to clients on the phone. Now, I can walk in the street with ambulance sirens on, and motorbikes roaring. They can hear something faint, but only notice if I ask. It is a little difficult to fit it on the ear. Be careful not to touch the disconnect button. Once you learn it and get used to it, it is simply perfect. Holds the charge very long. If I use it 8 hours a day, never dies on me.Additional benefits is that, if charged fully, blue light comes on. It has on/off button, connects with the phone immediately. I have JBL also, which is good, easy to put on your ear, but has no noise cancelling feature and picks up conversations from all the way far. It is very annoying for whom you are talking to.

lightweight, fairly comfortable
features are easy function. off and on button is difficult to see or find by touch, if not used to the length of mouth piece, can be a bit distracting, or you may think it would fall off or out of ear but it won't if you placed it in your ear properly. If you wear glasses depending on your frame and or shape of your ear may not fit as well over the ear, but that also would be a personal preference or taste in style. It is fairly lightweight and once you start wearing and using it you get used to it. Charges up fairly quick, Connectivity and pairing is good. appears to have a long battery life, meaning charge up in the morning or night before and your good to go all day and then some.. Distance from phone is about 40 Ft with out it being auto disconnected, but connection back within range is fairly quick as well. Quality is pretty good, Value for the money, I'd say yes. Ear piece size is pretty good but there again depends on your preference, I personally did not really care for what came with the unit for your ear, but found a style of ear piece cover that works much better.would I recommend this Yes!

Qualcomm fast and reliable connection but..
It is built with successful technology and a fast Qualcomm connection. But the speaker's sound was not much different from others and mostly required to be set near maximum.The battery life was great.Quality mediocre at best - the microphone lever broke in a few months....It didn't make it to a year...
