Review: 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.
Review: 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.

### ⭐⭐⭐⭐⭐ Great for dictation and battery life!
*by J***N on December 1, 2025*

These are the bomb! I got them for dictation on my computer and they work wonderful. I don’t even know how long they’ve kept a charge because I charged them up once and haven’t had to charge them since.
