Compatibility should remember, no other radio (eg. S5230)

1) The earbuds fit very well and but sit tight, not oppressive, but pleasant, thanks to rubber lip. Processing well. Lettering "Samsung" is both the listeners as well as on the adapter on it.
2) The sound is much more powerful than in the headset, which is included in the delivery of mobile phones. However, the sound is actually a total of somewhat dull, the highs stay a little on the track. Depends on the type of music that can be heard if this is very annoying or "over audibly".
3) also can be used as a headset for making calls. The adapter is a button for answering / Select, including Micro and this works well.

Large drawback however, is that in my phone with this headset is no radio reception is possible. On Adapter While "FM" is expressly imprinted, only noise is produced (as opposed to the supplied headset, which 1a radio reception offers). Not a single sender can be received.

Since I had specially selected this headset because of the property "radio reception", it was for me as a result a bad buy.

Well, in the compatibility list of the headset here at Amazon, the S5230 is not even listed .... Just funny that everything else works, not only just the antenna function ...
Keep your eyes peeled and watch whether full compatibility is assured ... otherwise the disappointment is inevitable.
