Blayz Bluetooth Sports Wireless Headphones with Microphone Noise Cancelling Sweatproof Earphones

They were good headphones. Purchased them in May of 2016. Took great care of them and usually put them in their case when traveling. Good sound quality. Then one day I unplugged them from the charger, went to the gym and.....nothing. Thinking that I didn't plug them in correctly to charge previously I made sure they were correctly plugged in to the micro USB charger. Waited until the next morning and nothing. Oddly enough I pressed the power button for 45 seconds (some suggest 10 seconds), released, then pressed it again and I heard "Power On". Alas, there was no connection and the headphones only teased me. They were durable as I dropped them a few times, but apparently only meant to last more than a year.

Ultimately I gave these 3 stars as they fit well and were relatively inexpensive (as opposed to high end options) but were fragile and had connectivity and battery issues (Additional details below):I purchased these for my wife to use at the gym with her apple watch, series 1 and iphone 6s. She was not a big fan as she ended up having connectivity issues with the Bluetooth and battery did not hold its charge as expected. As a result the headphones would stop working mid-workout or loose connection even when fully charged prior to the workout.I started to use them after she tossed them aside and had similar connectivity issues but not as bad as she decribed (I used with the iwatch series 2) and I was able to utilize them for my workouts as the earbuds did stay in while running. My biggest issue was that the quality of the headphones was sub-par. The headphones fell from my neck to the ground in the locker room and landed poorly. As a result the piece of the headphone with the power button popped off and I was not able to fix.

I hate bulky Bluetooth headphones, I don't just use my headphones to hear music or moves when on the go, I use them to separate myself from those around me. I have PTSD and need a distraction in waiting rooms, shopping basally anywhere where there are more than a few people. I don't like heavy headphones kind of negates the who Bluetooth idea these are great I have not used them for more than maybe 90min at a time but I have not ever ran out of power. they take some getting used to the whole cable over the back of the neck but if you forget and one falls off it will pull the other off as well. They are great and powerful compared to size much louder than I thought which is good I can drown out people easier now.

So far, these work well for me. I use them to listen to audio books on my Android Moto G (3rd Gen) smartphone with the Smart AudioBook Player app but haven't yet used them for a phone call. Pairing was simple. Sound is good. Volume works well - louder when needed than my wired headphones. They seem to last 6+ hours on a charge. The multi-purpose button works great for power on/off and start/stop play. They feel light on the head. The connecting cable (no noise when bumped, unlike my wired headphones) is a bit long, but a clip is provided to help manage it. Earbud fit was OK, but I use spare earbuds for a better fit. Three sizes were provided, which seems typical with headphones - as I said, one of these sizes fit me OK. Connectivity is good in the same room, but begins to drop off one or two rooms away. Connectivity also seems to cut out when I bend down with the smartphone in my front or rear pant pocket. I now use these instead of my wired headphones.I did test the headphones briefly with an iPod Touch (4th gen) and was disappointed by the function. The multi-purpose button started the built-in audio book player, but would not stop it. I didn't test it with a player app. Volume control was not as good either.I wanted Bluetooth waterproof headphones for swimming, but I haven't tried these yet and may not risk it. The waterproof screens on the tips of each headphone side came loose when I removed the earbuds so they aren't well attached. Also, the rubber charging cover seems to fit loosely. I have used Sony Walkman Waterproof headphones for years and have found the earbud fit it critical, but sometimes water still leaks past and the screens are then needed to protect the headphones - I don't trust these screens.

I returned these headphones for the following 2 reasons:1. When I connect via Bluetooth I have to do this 3-4 times before the sound stabilizes and stop cutting in/out. I go to settings/bluetooth and the device is fully connected, no wavering, when this is happening. All the fiddling around interferes with my exercise routine.2. The headphones work better when my iPhone is on the right side of my body. The sound quality is more distorted and wavers when my iPhone is on the left side. The sound also waver if I put my iPhone in my pockets when I walk.I like the sound quality once they finally start working.Note: I’m using this mostly with and iPhone 5S and sometimes with my iPad. Software IOS 10.0.2 is on both devices.
