I wouldn't recommend Beats as you're paying for just the name and a pair of earphones that have an EQ forced within them. If you are looking for good quality, and something that is easy with the ears, I would recommend the Shure SE535 IEMs. Paired with lossless audio (WMAL), you'll have a great sound coming from the phone (when the EQ is compensated correctly to remove any flatness to the sound).
I know the SE525s are in-ear but they don't feel like earbuds in that sense. The way they fit to the ear, it makes them more like a hybrid really.
Bluetooth earphones are never a good idea; the lack of bandwidth will seriously degrade the audio quality, and should someone be using Bluetooth nearby, it can also interfere.
