@safari I have Shokz OpenFit and OpenFit 2. Spark looks almost identical to OpenFit 2 but less expensive. I wonder what are the differences and in terms of sound quality and whether it is worth choosing Suunto Spark over that specific Shokz model.
My experience with using OpenFit and OpenFit 2 during trail runs and races has been very positive. The headphones stay put and are very comfortable, and I can wear them for hours and usually forget I have them on my ears if they aren’t turned on. They didn’t obstruct ambient sounds in any way. Usually I don’t use the noise cancelling feature. The reason I mention that is because again Suunto Spark looks almost identical, so I assume that everything I mentioned would apply to Spark as well.
Also. I should mention that the lack of a physical button may be an issue. That is the main difference between Shoks OpenFit and OpenFit 2, and the touch control on the first version is finicky and unreliable, especially in a rain or when headphones get wet from sweat. I much prefer the physical button on OpenFit 2.
