I'll keep this short times (radical yes in the video):
Super, small player for less money. For me more than loud (only techno stuff hear while running) with the right headphones (eg Sennheiser in ear 630). Find the Bass also OK. The equalizer is fürn A .....
The player also has a clip so you can attach it to the sleeve of the T-shirt in fine (cable arm / shoulder along out). The thing weighs indeed as good as nothing.
Conclusion:
Who needs a small, lightweight player for running should access here quietly.
