H300 Wireless Headphones Bluetooth with Microphone, Over Ear Headsets with USB Dongle & Mute, Environmental Noise Cancelling Retractable Mic for Work Office Meeting Laptop Computer (Black)ClimatePartner certified

The media could not be loaded. 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.

I am pleased with this purchase I made five months ago today. The seller shipped it fast, and the headphones arrived safely. I am also very happy with the headphones. They are, in my opinion, a good quality and sound good for the price. They are comfortable and put together nicely. I love, love how fast they charge and how long they last when charged. I would recommend this product and the seller.

TL;DR: great output, good range, mediocre input, pretty reliable.Audio quality is rather good, the sounds from gaming and meetings can be clearly heard.The range is pretty good, I can to my living room and it'll still connect, much further it gets cracklyThe only bad thing is the microphone, I am a quiet speaker and the microphone makes is worse as it too is pretty quiet, even if I put it right in front of my mouth and talk loudlyit has lasted me over a year so far, still holding on despite the rough treatment I often put them through, only damages are one of the folding parts broke off, which is understandable as that's a point of failure due to how it can't be directly supported, and the cover of the top padding slightly pealed off on the front, most likely from the common quick shifting in positions I have to do due to it's decent noise canceling.

Unexpected Customer Service. They did not have to help resolve my issue but they did. This says alot about company integrity. You've earned your 5. Thank you!These headphones were solid 5 until the left pin shifted and pops loose daily. Headphones still work, but left side is a bit wobbly. Unfortunately this happens 5 months post purchase.

This is the 3rd pair of headphones I bought from COOSII. The first two were the P80C and they worked great. I work from home by phone and the mic was great and audio clear. I could pair these headphones with my iPad and my phone. Unfortunately, the P80C is no longer available, so I bought these. I can only connect my phone OR iPad at one time. The mute button used to be on the mic arm, now it’s on the side of the ear so it’s not as convenient. Setup was easy and they’re comfortable enough to wear all day. I wish they hadn’t changed those two important features, so that’s why I gave it only 3 stars.

I love it that's a good product

Worked great at first. Has wonderful background noise filtering. Comfortable headset. Unfortunately it won't connect to the dongle anymore after just a few months of use and I cannot use Bluetooth on this particular device.

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!
