I suppose the version with cable is more comfortable, because in the Bluetooth version of the speaker is very thick and angular and therefore very uncomfortable in the ear. The keys slipping easily off the above-stitched mask and makes the operation thus heavier. An independent from the speakers Bluetooth receiver is inserted back into the band, I would prefer.
The contrast sound is acceptable if the speaker to the right places Pushes, unfortunately for me the place right also the most unpleasant to my ears.
