I'm addicted to these type of earphones! I already bought a sleep mask from the same company. They both have the same quality, which please me immensely.UPDATE: I'm sad to report that I've been getting headaches from this item. The band squeezes too much from extended wear. But I found a hack to decrease the tension it causes.HACK: If you feel like the band is too tight, move the control out of the "pocket" and let it float in the headband while wearing. It decreases the tension and is still usable. Solved my headaches I got from wearing it. :)FABRIC AND WASHABILITY: This is a lightweight headband type pair of earphones. It has breathable fabric, like those stretchy type shirts you use for working out. I'm just worried the stretchy feel will become "too stretchy" over time. I imagine after washing it and drying, it will retain it's original shape. And yes it's washable. You can remove the electronics part as a unit. You need to remove all at same time because it's all attached together. There is room to slide them through, it entails stretching the fabric to pry it out.USES: I plan to use it to go walking outdoors and while on treadmill while watching my shows on tablet. I also think I can squeeze in meditation sessions and perhaps to work as a delivery driver.BUTTONS: Sensitive to touch. The placement of buttons are above the buttons you see on the headband. It makes a clicky sound. The forward and back buttons will take you to and from the next song by pressing once. Holding it down will increase or decrease sound. The middle button (power button) serves as a pause and play button. I have not tested answering or rejecting a phone call via buttons yet. You cannot feel the buttons individually, you'll just have to get used to it.BATTERY: Long battery life. It seems to last longer than my phone, lol! I'm a heavy phone user so my phone doesn't last as long as it should. I'll update with how many hours on average I was able to use.BLUETOOTH: I was able to set my phone down, walk away outside and scold my dogs for harassing the neighbors, lol! That's at least one wall between my phone and headset with no disruption.PHONE CALLS: I already received a phone call through this set. Caller was able to hear me clearly and I could hear them as well. Such a great plus.SIZE: I'm not used to wearing things on my forehead, so I guess it will take getting used to. I decided to file the front half inward, to give my face breathing room...we already have to wear masks outside our homes. My face feels overwhelmed by the size of it, by folding it in half at the front area, it did not disrupt the electronics.AS A SLEEP MASK: You can pull these over your eyes like a sleep mask. It's not a complete darkness like the other set the store sells. But for quick naps on the go or a meditation session, it's great.SOUND: Generally great. IT IS NOT SOUND CANCELLATION HEADPHONES. The speakers sit next to your ears. The sound gets loud enough to enjoy music and phone calls but noise will come through. I like that because for the purposes I need them for, I need to hear surrounding noises. While walking outdoors, is a matter of safety. As a food delivery driver, I hate having to remove ear pieces to speak to customers or restaurant hosts.NOTE: My phone has an app that came with it that affects sounds quality. It's a Motorola G Stylus. The app makes sounds louder and more crisp. I think this can greatly affect your enjoyment of these earphones. Try to download an app to increase the quality before giving up on this set.I'm planning on buying more for gift giving :)
