Our Verdict

Fitbit Flyer Wireless

Sony WI-SP600N Wireless

The Sony WI-SP600N Wireless have about the same performance as the Fitbit Flyer Wireless, but they're more customizable. The Sony have a better companion app, which gives them a lot more options and features you can tweak to better your listening experience. They're also noise cancelling, so they do a bit better for commuting. On the other hand, the Fitbit are a bit more stable for the gym with a smaller and easier to use in-line remote. The Fitbit also have a longer battery life and offer slightly better value for your money if you do not mind not having an EQ.
