*I ordered this on Sun. Oct 17th and it showed that I should get it by Weds., but instead got it the next day, just lucky that my local distribution center of Amazon had it in stock here in South Florida.*I'm writing this review on Nov. 16th, so just under a months usage.*I explain at the end of the review why I rated it a 4 instead of 5Every day I take my 16 year old, non verbal Autistic son out for a bike ride and a walk every day. I like how with the Bludio, I can listen to my music without covering my ears with speakers, so I can still hear what's going on around me. I go out every single day rain or shine for between 5-10 miles, or between 45 to 90 min on the bike and then for about an hour walk. Usually the battery only gets used up around 10-15% per hour, so I imagine that it could go on for several hours. Never had it die on my so I don't know. About a week ago, we were out biking and it started raining HARD... remnants of the last Tropical storm. The speaker got SOAKED and stopped working. When I got home, I hung it up on a hook with the port parts draining down. The next morning I wrapped left it out in the Sun, on top of a picnic table in my back yard. I had to bring it back in later because it started raining again, but repeated the process the next day. Within a couple of days the speaker started working again, once it was fully dried inside. Yesterday it started raining while we were out on our bike ride again, but this time I was prepared and wrapped the open ports in a sandwich bag.*I've also used this to listen to Youtube or Podcasts on my Alexa Show at a low volume in the kitchen, while the rest of my family is in the Family room watching TV.*Why I rated this a 4 and not 5When I first saw the Bose Soundwear, I thought it was a fantastic invention. I tried one out at Best Buy and REALLY wanted one, but couldn't see myself spending $400.00 on such an accessory. Even now, that it's dropped to $299.95 here on Amazon, for me is just way too much. I REALLY liked the soft flex design of the Bose and when I first saw this, I thought it was a copycat for a tenth the price so I bought it. What I didn't realize is that it's a very hard and inflexible plastic. While not as comfortable as the Bose, it's actually very comfortable ... just not what I was expecting, and as a side note I wear this both with and without a shirt, but usually without... especially when I'm, biking.*The main reason I rated it a 4 is because the speakers sound pretty flat with very little range. Again, my only other experience was with the Bose which costs 10X more, but I've even had ear pieces that have better Bass than this. It's not horrible, just a bit worse than I expected.*Final Thoughts.If you're looking for wearable speakers, but don't want to spend a fortune these are a very good buy. You are sacrificing a bit of Bass, compared to most headsets, but this has decent sound quality and is especially good if you want to listen to music, the TV or a Podcast at a low volume without disturbing others in the household. Great for biking, but not as good for running as it does tend to jump around on your shoulders a bit.
