Nice, solid, reliable headphones
These are very nice and are exactly what I was looking for. I wanted reliable over-the-ear bluetooth headphones that I could use in calls. These are perfect. Someone calls and I can pull out the microphone and answer. Sometimes I keep the microphone slightly out so that I can take a call without touching the headphone. NOTES * The microphone. It has a little blue light on it to show that it's active. Push it all the way in and it automatically mutes. Easy to adjust. - NOTE: One thing about the microphone is that it is sensitive to airflow. Breathe on it and the sound is very loud to the person on the other end of the line. That turns out to not be a drawback, you simply don't need to position it in front of your mouth. Voice volume was very good when the microphone was pulled straight out. * USB-C charger. Yes! It also came with a USB-A to USB-C cable, but I'm now basically able to charge it anywhere in my house that I charge my phone. I was so glad it didn't come with a finicky micro-USB cable. * The Bluetooth connection was solid. I was able to go into the garage and listen to music without interruption. My phone was about 60 ft away through 4 walls. I don't really have a comparison point, so I don't know if this is great, but I did expect to have it drop. Connecting it to devices was quick and easy. * Battery life is good. I didn't try to play music for 40 hours, but it didn't seem unrealistic. I last charged them 9 days ago and the battery is currently at 40%. I don't listen to them every day for hours, but I had a pair previously that would drain in a week with very little use. * Sound quality. I'm no audiophile, but the sound reproduction seemed very good. They handle bass better than I expected. The noise cancellation seems to work for music, but maybe that's just the earpieces fitting very well over my ear? The noise cancellation is supposed to only work through the microphone. * Portability. They fold up nicely and can go into my bag without getting tangled with cables. The microphone is ESPECIALLY nice here as it goes into the earpiece so that it doesn't grab every cable in the bag. * Hard-wired connection. I like to have this option, but I didn't test it. My kids will sometimes run out of battery in their headphones and it would be nice to have a hard-wired connection available. If you have a source that can connect that way... * Bluetooth dongle. I tested this just to test it, but my laptop has bluetooth built in, so I don't really need it. Again though, I love that it's available. Even if I don't need it for the headsets, I now have it available in case I'm ever in a situation where it's needed. Anyway, it worked just like the internal bluetooth. * The build is solid. I feel like they will last. They don't seem cheap at all. Overall, a great value.

Comfortable for lots of meetings/calls
I work from home and my job requires plenty of calls and meetings. These are comfortable and the battery lasts much longer than expected. No issues with connecting it to my laptop Bluetooth, however you want to have your screen open on your laptop. If it is closed, I found that the signal won't be as strong and the call will sound muffled. That is not a deal breaker for me as I usually have it open anyway. I went from a wired headset to these. The wireless is a must. If you need to get up to close your door or just stretch during a long call, this makes it possible. It is a good value for the money. I have had it for several months and it has held up well. It charges by USB-C which is also convenient as it is the same wire I use for my phone. I charge it once every few days. Overall I would recommend it. My wife even bought herself a set as well.

Good, not great
These headphones are comfortable. I can wear them all day at work and never get uncomfortable. Easy to set up, but the mic seems to have issues. On teams calls other participants have issues hearing me.

Unreliable - Used for over a year
I have used these headphones/headset for over a year at work and am coming back to say try a different option. These headphones are decent for the most part. Battery life is good, mic sound quality is good. The number one major issue I had was this headset would just drop sound randomly (not run out of battery & not disconnect). I mostly used the USB dongle as the Bluetooth mode did not work well with my very standard Dell work laptop. I had tried my dongle in the laptop and in my dock and had the same issue regardless. When they drop sound, I would have to reconnect the dongle or power on/off the headset or both, to get it to work again. The power off button takes a ridiculously long time to hold down to work, leaving me in a scramble in many calls to get these thing working again. If you are ever leading a call, you don't want to be messing around with this. Also, listening to tunes at work, the sound quality wasn't always great, sometimes there would be a crackle (like an old record). Like all reviews, take this with a grain of salt, maybe I had a bad pair. There are a lot of private label electronic brands on AZ and you never know how its going to go. I likely won't learn from this mistake and will try another brand that you'll never see inside of an actual store. Good Luck!

*Horrible headphones for the price. Search for others.*
This is my first time writing a review and I never thought I would make one but due to the circumstances, I was forced to write one. I've been a mid to cheap price headphone user for the last 12 years so you can trust this review that you're about to read: 1) At the beginning, the headphones were normal and as expected, but when the headphones had low battery, the headphone always shouted very loud every 3-5minutes "BATTERY LOW". It was extremely annoying because it didn't had the feature of going off to save battery like other headphones and I'm a person who goes asleep with them on very frequently, and waking up to the "BATTERY LOW" was a horrible way to get woken up to (even if you had you headphones far away in your bed). 2)Not even a month later, the headphones started to make this beeping low white noise sound when they were turned on. This isn't a one time sound, it was a permanent sound once they were turned on, which distracted you from the music or sounds that you were trying to listen to. Never in my lifetime I've encountered this situation, and I used to always buy very cheap gaming headphones when I was a kid. 3) Build quality lasted literally 1 YEAR. I've never encountered a situation were a headphone I spent a lot of money on was BROKEN a year later of it's purchase, and not only that, it also started to peel off. I really miss my razer barracudas x that lasted me almost 4 years; too bad they don't sell them on amazon anymore.

The Mic is the noise cancelling part, not the headset
I bought this after I read that it has active noise cancellation. Turns out that the Mic is the noise cancelling part, not the headset. I should have known better. but anyway, the product is good and does as advertised.

Useful for short meetings
Headphone feels heavy within 30 min of usage. Overall mic and sound quality is good.

Good quality headphone
I like the product as it is good quality voice, good plastic and fit in my budget. Over all sound quality is great and it works perfect for gamming, and online calls. Wireless feature makes it easy to use and charge time is very decent.

Failed after 9 months
*2nd update - I received my replacement unit, and I have a couple of observations. 1) The mic doesn't mute when tucked in all the way, but my old one does. I think that's technically a fault with the unit since it's advertised to do so. It doesn't bother me personally, since I didn't care one way or another for the feature. 2) The plastic doesn't creak on the new unit when you move it around, but it does on the old one. I'm not sure if that's something that developed over the 9 months, or if this band is made of different plastic and now it's fixed. I'll leave it as a 4 star review since I do think it is a good product - the speakers are very good. The mic, I'm told is good and my coworkers can hear me fine (used for meetings for many hours a day), my ears are never sweaty and they're lightweight enough that I don't get a headache or discomfort from wearing them. The pads feel exactly the same between the old pair and the new pair, so they should last for quite some time. The new pair feels slightly tighter on the head than the old pair, but I'm sure it'll stretch a bit over time. I just hope the band holds up on the replacement. *1st update - customer support has offered a replacement even though it's outside the return window. Hope I just got a one-off the first time and the replacement is better.* Original review - I really liked these headphones, used them for hours at a time for work and playing at the computer, was able switch it over to my phone quickly and go for a walk outside with them. Unfortunately, after only 9 months of use, the headband broke unexpectedly in the middle of the band. They didn't even have a crack on them previously, otherwise I would have tried to patch it before it cracked. Not sure I'd recommend based on the lack of durability.

I like this headphone very much
I like the following feather of this headphone. 1). It is not heavy, comfortable for wearing. 2). Sound quality is good. clear enough. 3). It has actually three connection ways - USB dongle for computer, wireless blue-tooth for cell phone, and a cable for general device. I can switch between computer and cellphone with one button. This is the best feature I like. 4). Retractable Microphone.
