H300 Wireless Headphones with Microphone,Over Ear Bluetooth Headsets, Black

I’ve gone through quite a few headsets for my office, and the COOSII H300 is easily my favorite so far. From the moment I took them out of the box, I could tell the build quality was top-tier they feel sturdy yet surprisingly lightweight. Comfort & Battery Life: The comfort level is superior. I often have to wear these for 6+ hours a day during back-to-back meetings, and I don't get that "clamping" feeling or ear fatigue that usually comes with over-ear headphones. The padding is super soft! Plus, the battery life is absolutely insane. I can go several days on a single charge without even thinking about it, which is a total lifesaver for a busy work week. The Standout Feature – The Mic: The retractable mic is a game-changer! It’s so sleek and tucks away perfectly when I’m just listening to music. But the best part? It has a clever "auto-mute" feel when you retract it or use the dedicated mute function, it’s instant and reliable. My coworkers mentioned my voice sounds crystal clear even when there’s background noise in my house. Pros: • Superior Comfort: Perfect for long shifts or gaming marathons. • Amazing Battery: Truly long-lasting performance. • Retractable Mic: Super convenient and mutes perfectly during calls. • Dual Connectivity: Works great with both the USB dongle and Bluetooth. If you’re looking for a professional-grade headset that doesn't sacrifice comfort for quality, look no further. This is an absolute 10/10 purchase!

Very comfortable and easy to connect. The sound is clear, and the microphone works very well for calls or work. I really liked that they isolate noise quite effectively, and the battery life is excellent. Plus, they feel lightweight and comfortable, even after several hours of use. An excellent purchase for the price.

I bought these headphones for my personal use because I needed something comfortable and reliable for my calls and daily activities. From the very beginning, I noticed how lightweight and easy they are to use. I can wear them for several hours without discomfort, which is very important to me, especially on busy days when I need to stay focused. The sound and microphone quality have been very good. Calls are clear, and people can hear me without any issues, even when there is some background noise. This gives me peace of mind and confidence because I can communicate better and complete my tasks without interruptions. I also like that the microphone can be easily tucked away when I’m not using it. Another feature I really appreciate is the battery life, since it lasts a long time and I don’t have to charge it constantly. Overall, I consider this a practical, comfortable, and functional product. It has met my needs, and I would recommend it to anyone looking for reliable headphones for work or everyday use

It took a hot minute to find this kind of headphone specific to what I was looking for -- one without a 'dongle' attached to the headphone cord, wireless optional, low-profile or retractable mic -- and I'm glad I finally did. Overall, it's been a really nice headset over the last week of having it. My only real gripes is that the headphones themselves don't really have cushion on the driver; they cup over the entire ear and in turn the rim of the ear rests against/is compressed against it, and in turn it becomes uncomfortable/painful to continue wearing after an hour or so -- at least for me. Only other thing is the level of bass the headphones have is enormous compared to the mids and treble; resulting in a great sound experience for games or some music, but not so much for talking with others, as voices often sound muffled, and if you're in the realm of production for music or anything audio-sensitive it gives a false sense of bass leveling. The third gripe I have is with the little voice that plays when something goes on with the headset, primarily with "Low Battery" and "Microphone Muted/Unmuted"; it's just a little intrusive, it mutes the audio then plays the voice line, then goes back to audio. Which wouldn't be so bad except that for Mute/Unmute it makes a "push to talk" type approach very difficult where timing is important, and for "Low Battery" it repeats the line about every 4 minutes. Don't need it to happen that often; just once is fine, or replace the line in future revisions with a non-interruptive double-beep noise. As far actually using it otherwise, it's been a breeze. Right out of the box it's "plug and play"; turned on the headphones, plugged in the wireless USB dongle/adapter, and it immediately connected; and swapping between my PC (using the dongle) and my phone (using Bluetooth) is as quick and easy as pressing the pairing button for 3 seconds, as is using the auxiliary cord; plug it in, the headset immediately/automatically powers off if it is on and swaps to analog. The battery only takes about an hour and a half to charge, and lasts about two cumulative days (roughly 36 hours). All in all, 4 stars from me. Just wish the bass was a little lower, and the voice lines for Low Battery/Mic Mute were non-interruptive.

I’m really impressed with these COOSII H300 wireless headphones. The sound quality is excellent — clear highs, solid mids, and surprisingly deep bass for the price. Music, movies, and calls all sound great. The headphones are also very comfortable. The ear cushions are soft and fit nicely around the ears, so I can wear them for long periods without discomfort. The adjustable headband feels sturdy but still lightweight. Pairing with my devices was quick and easy, and the connection has been stable with no dropouts. The built-in microphone works well for calls and gaming, and the battery life lasts a long time between charges. Overall, these headphones offer fantastic performance and quality for the price. If you're looking for comfortable wireless headphones with great sound, I highly recommend them!

Firstly, let it be known I am working in a call center, so I am looking for a decent set with great sound quality and comfortable design. The headphones felt great and I loved the retractable mic! I had 3 main issues with it which have led to me returning my purchase: 1. I had 2 calls that I ended up disconnecting because I was talking and there was no response. Turns out my microphone was muted even though the status light was on, and I had previously been speaking fine. This was a major reason 2. Sound quality was not great. I'm not a sound expert by any means, but there was some reverb that made understanding callers difficult. This was a big factor. 3. The toggle between Bluetooth and USB was too delayed to be practical in my work environment, so I was unable to take advantage of this feature. That only minorly contributes to my return.

I’ve been using the COOSII H300 Wireless Headphones for a while now, and they’ve honestly made my work calls so much smoother. The sound quality is clear and balanced, both for listening and speaking. The environmental noise-cancelling mic does a great job—people on the other end can hear me clearly even when there’s background noise around. The retractable microphone with mute function is super convenient, especially during meetings. I also love the USB dongle option, which makes it really easy to connect to my laptop without any hassle. The Bluetooth connection is stable, and switching between devices is pretty seamless. Comfort-wise, these are great for long hours. The over-ear design is soft and lightweight, so I don’t feel any discomfort even after wearing them for extended periods. Battery life is solid too—I don’t have to charge it frequently, which is perfect for busy workdays. Overall, a reliable and affordable headset for work-from-home, office calls, or call center use. Highly recommend

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!

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.

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

I have been using the headphones everyday from r over two months and they are fantastic. The battery life is amazing. The sound is excellent. Very comfortable as well. I highly recommend.

*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.

Works great and very comfortable
