Summary Overall , this pair of headphones are worth the price. It worked with my Samsung Galaxy Ace with a Bluetooth 2.1 (A2DP). I could even use the NFC function by downloading the app from Google Play Store/App Store. (NFC Easy Connect) . Though the volume isn't the best , but in terms of price, portability , the clean bass and all , its all worth it. No more messy chords , tangled wires and damaged wires that kills your headphones !
One more thing , the microphone is the part where i have to really praise about it. Good Job Sony ! My friend was able to hear clearly what was i talking about. I was shocked. I was talking at a soft voice and my friend could actually hear me. The controls on the headphones also work well.Volume Up and Down, Pause , Fast Forward and Replay.

Then DR-BTN200M will be the headphone that you are looking for !
