First off, these headphones and the case have a very sleek design! It took a little getting used to putting them on as they are not your typical earphones. But once on, they stay put and feel both comfortable and light on the ear. This works perfectly for my needs, as a mother who would like to hear my kids around me when they're playing, while doing things around the home! I can listen to audiobooks, etc and even make calls while still being fully aware of my surroundings. I usually get headaches after using my AirPods, by using these I did not get any! So I feel more comfortable wearing them, knowing they aren't as bad on my health. The sound was great as well over my ear- it's like a speaker over the ear without blocking out any outside noise. That's exactly what they are supposed to do and the main reason why I bought them!

I love these earphones. They are comfortable on my ears and it's so easy to use. The battery life on them is phenomenal. I've had them for somewhere between 6 to 8 months, and I use them every day. Super happy that I purchased them and I definitely recommend them keep in mind. That these earphones do allow you to hear your surroundings. So if you're looking for earphones, that's going to block out all noise. These are not them. These allow you to still hear your surroundings. But enjoy whatever you're listening to. And they're also great for conversation On the phone

I wanted a set of open air wireless ear buds for some time. I got these on sale for $30 ten months ago. I do not use them daily. All the features work well. I like being able to hear people talk and the environment around me. The sound quality is fine by my standards. I have had zero connection issues. I have dropped them enough to know they are durable. The case is well made, though a bit big to carry in your pocket. No problems, I would recommend them at the regular price.

They are very nice and sound good but they are not to my taste because despite being comfortable for my taste I prefer not to hear the outside which this one offers, you hear the music but also the outside.

I paired them with phone and the result was very good. I can hear everything around me. I measured with a lasering device and was able to have a good connection at 40 feet away. The quality of the sound is good, I can hear hiqh and low frequencies for about as well expected for this type of device.
