Looking for headphones that won't fly out of your ears on a run or ride? These might be a good option. I have done both, but I actually prefer to go without headphones when I'm using the roads. That's just me. That said, my favorite way to use these is when I'm doing lawn work, walking the dog, and stuff like that. I can still hear environmental cues, but can enjoy music at the same time with the added confidence of not losing an earbud in the dirt or in the creek or something frustrating and preventable like that. I do find the behind the neck loop to be a bit of a pain depending on hat/hoods or whatever, but my use of the Shokz OpenRun has primarily been during the fall/winter. I think these may prove to be even more useful in the hot months. Can't wait to find out.
I have had many heart rate monitors over the years. Polar, and Garmin. This heart rate monitor is worth the extra money in terms of of performance. I have a swim Garmin HRM which is very similar but this one is more confortable. I have optical HRM but I prefer the chest strap because it uses electrical impulses to measure heart rate which is capable to detect Atrial Fibrillation; not so with optical technology. The storage is handy if you are doing a sport where you receiving device is out of range. At the end of the activity it downloads your heart rate data for the session. You have to make sure the device is connected to you HRM before you start the activity for this to work. The Bluetooth/ANT functionality works well also.
With the accuracy of modern GPS computers the speed sensor might be considered obsolete but I still like using them for one reason. I ride enough bike paths and roads with heavy tree coverage that block GPS signals so I get inaccurate readings without it, call me crazy but I like looking at my current speed and knowing it is correct, there is a slight time delay but that is easy to get used to. The Speed Sensor 2 definitely gives me accurate readings that are verified when I pass the digital street signs that display your speed, the auto-sizing feature is a really nice touch as well.
I use the Varia Tail Light/Radar on both my road and gravel bikes. I set up mounts specific to each bikes seat post. The O ring straps only last for a limited length of time before they break so attaching a tether from the device to the seat post provides extra security. A tether should be included in each package. The rubber adapter pieces that nest together are easily lost when changing bikes. Spray adhesive can be used to keep these pieces together.
