Worth the money
This Bluetooth headset is easy to connect and works perfectly. The sound is clear, and the microphone quality is very good for calls. It’s comfortable to wear for a long time, and the battery lasts well throughout the day. Great quality for the price. I highly recommend it.

High quality Bluetooth earpiece
This is one of the least expensive most high quality Bluetooth earpieces I've ever owned. I've tried higher end Jabra, Google and Galaxy earbuds. Most of them at least for me, work like ear plugs blocking my hearing from my surroundings. I like this form factor. This may not be for everyone but for those looking for a mono Bluetooth earpiece to wear in one ear, this is it. The soft gel earpiece does not obstruct your ear canal and prevent you from hearing what's going on around you. It's build quality is phenomenal. It has all day comfort. I was worried about comfortability at first but after wearing it all day, I realized I was checking my ear to see if I had lost it. I literally couldn't feel it because it's so comfortable. It has incredible sound clarity and the volume level is more than adequate. It's loud. Loud and clear. Also, it's very sleek and attractive. I would have liked a matte finish instead of the gloss just because of the problem with fingerprints. However, it's certainly not a deal breaker considering this is such a quality product. It is very reminiscent of my Plantronics M165 Marque 2. The functions are very intuitive and easy to use. There is a volume rocker on top. It has a mute button on the bottom. This is while wearing it in the right ear. These buttons will be inverted if wearing it in the left ear. It also has a multifunction button on the side. One tap of the multifunction button will play music. Double tap the multifunction button to redial. Long press it to turn on and off. Use the mute button during calls or to open your assistant when you're not on calls. This is a great Bluetooth earpiece at any price. The fact that it is a little over $30 is phenomenal. I would highly recommend it to anybody that likes this particular form factor. As I said earlier in this review, it's a very high quality, well built, incredibly clear sounding Bluetooth earpiece.

Works better than expected, would recommend depending on your usage
Works pretty well overall. This will connect to 2 devices at a time. I connected it to my phone & a laptop. It will work with one device at a time & doesn't toggle seamlessly between them. I have to choose to activate it on the opposite device to use the second one. A bit of effort, but pretty simple if you are sitting at your computer and expecting to take calls on both. The sound volume is better and much higher than my many years of Plantronics and Jabra similar devices. The sound also works for calls & media, music, videos etc. Some lower end similar devices only connect for calls and zero additional media or sound so this is a large step above those basics. The on/off button does take several seconds to turn on and off. My phone is set to auto answer so when on, it is not an issue for me. If you are going to turn it on/off all the time, that may be cumbersome, but that type if usage already is. The headset will stay connected to my phone for 35 or so feet away which is a little less than Plantronics or Jabra, but similar coverage within my home. The ear loop piece doesn't fit at all, but I replaced with one from a previous similar device. If you don't have a different ear hook, it would be worth purchasing a different one if possible before damaging or losing this device. It does sit light on the ear with the different ear hook. It allows some outside noise to be heard unlike traditional ear buds that block everything out which is my preference for using this device. Overall I would recommend if your usage is similar to mine. I am going to order a couple more before this technology disappears as it actually works much better than expected.

Cheaply made!
I bought this device in 2023 and replaced it in 2024 due to my fault. Then in 2025 I replaced it because the ear piece broke off. The device that I got was not the same as I purchased in 2023 and 2024. It no longer had a mute button at the end of the headset and the ear piece was smaller which is good because the other one would hurt my ear. I love this headset because it tells you the name of the person that is calling. Now the reason that I gave it one star is because when I disconnected it the part that goes on your ear broke! It came out with wires and all. Same happened to the one before. I only have had it for 3 months! No longer will buy this item and this was my 3rd time buying it! If you buy make sure you get the warranty. Trust me you will need it. Gosh I so miss my planatronics devices!

Prone to accidental powering-on.
This earphone works fine as an earphone except for what I consider a design flaw. The on/off switch is actually a button on front of the earpiece. It is raised, so that any small amount of pressure turns it of or on. It was regularly turning on if I had it in my pocket or in a pocket of my carry on luggage. It wasn't just annoying; it would run down the battery and activate the audio book on my iPhone so that I would have to search for where I left off the next time I wanted to listen. Worse, if in the car and it self-activated because of some pressure on that raised button, I would miss a call ringing in the earphone so that I was unaware of it unless looking at my phone. I replaced it with another brand that had a sliding switch not prone to accidental powering on, unfortunately too late to return this one.
