Those are likely to be quite good, Nokia has made some decent bluetooth gear over the last few years. I'd be worried about moisture from sweat destroying those over time though, that's what happened to the same style Moto S9's I used whilst exercising a couple of years ago (and is a very commonly described fault of that headset).
Personally I'd recommend the Samsung HS3000. It's a small bluetooth receiver with playback and volume controls that you can plug whichever headphones you like into (or connect to stereo via 3.5-3.5mm cable etc). Very versatile because of that - I use it with my over-ear hook Sony IEMs for cycling, and occasionally for connecting to stereos, or my Senn HD25-1 IIs. It is bluetooth 3.0 and crucially has Apt-X, which gives far better bluetooth sound quality and a degree of future proofing. To top it all off it can be purchased very cheaply online too.
