Definitely a good choice

I was given the bad reviews a bit skeptical, then have me but struggled through to buy the Groove Buds and have not looked back.
The price-performance ratio is not to exceed in my opinion.
Featuring / feel:
The headphones make a high-quality impression, the cable is just flexible enough without being too stiff, or otherwise too easily entangle. The silicone tips fit perfectly.
Sound:
Sonically, the buds do not weaknesses. The complete spectrum is reproduced sovereign, nothing is swallowed. It is always all visible, even quieter background passages. All volumes are equally well represented. (Reference: Dead Can Dance, 320kBit on Creative Zen V).
Conclusion:
I'm really looking at the good and favorable listening. The negative reviews I can not understand personally and recommend the Groove Buds fully.

An addendum this: I have the headphones still (yes, there are still the first, now 3 years old) and use them mainly in sports, so they are quite good and they make claims still outstanding.
