Love that I can leave my phone in a locker at the gym and have quality sound coming out of comfortable earbuds that also look really good (they don't stick out or hang down like the Apple ones). The 4gb of internal storage allows for plenty of music to be stored into the earbuds while you can put songs in different folders and hear the songs that you want to. While on a plane or even around the house I can be connected via bluetooth to my phone or another device and access whatever music I desire by streaming it to the Bragi Dash Pro earbuds. There is plenty of battery life to get you thru a workout or almost a cross country flight and the option to swim with them makes them even better!Sound QualityWhile not the quality you can get from over the ear headphones, the sound quality is quite good with the foam ear tips creating a nice seal which provides plenty of bass for me. Some have complained about the volume not being enough for those intense workouts but with the update that Bragi did in July, these things have plenty of pop for my workouts. And I am one that likes loud, hard rock music to workout to. I gave the sound quality a score of 4 stars because of the issue I'll get to in the next section.Minor IssuesEvery once in a while the music can cut out for a split second. Not sure if that is a bluetooth issue or is an issue with communicating with my phone. But I have read where people with wireless earbuds have experienced this issue and complain about it. I'd say the Bragi Dash Pro, considering all of the features you get, check so many boxes that I can live with an occaisionaly cut out. These gaps in the music don't happen too often to make them annoying AND, Bragi has the ability to update the earbuds so they may create a patch to improve that minor issue.Some have complained about the charging dock being too big and difficult to get the buds in correctly. I don't feel the charging dock is too big and as long as you pay attention to the lights on each earbud, you won't mess up and put them in the charger incorrectly.TranparencyWhen you pause music and have transparency off, you can hear all sorts of things around you like you are a superhero. Outside sound is pumped in from the direction the earbuds are facing. Helpful in that you don't need to take out the earbuds that have such a nice seal that you might have difficulty hearing a person talking to you without this feature. I wouldn't get earbuds without this feature.WorkoutsThere is a heart rate monitor and the ability to track your workouts. I haven't used these features as I am pretty simple and mainly want really good sounding music in comfortable reliable earbuds. As far as staying in place, I have had issues with other headphones or earbuds not staying in but the Bragi Dash Pro stay put even during intense hard running or even jumping around on the basketball court. You just have to find the right size foam ear tip for you and once you do, these things will stay put.ControlsWith taps and swipes you can manuever thru whatever you want to do. You have to get thru the learning curve of where to tap and swipe but it doesn't take long to figure out where you need to tap or swipe. Just be patient.SummaryI have gone thru many wired and wireless earbuds for workouts/running and Bragi Dash Pro has hit a home run with these. If you run, swim, workout, travel or want a truly wireless option for everyday life that has as many if not more features than any other earbud on the market with awesome sound quaity, then order these and don't look back. Enjoy!P.S. I was NOT given anything for this review. I waited until I used these for about a month to write a detailed review of my experience with the Bragi Dash Pro.
