Short answer: the two are close, and bass depth is the shared compromise. Our notes call the Teufel Rockster XS a good sounding speaker, though its bass is not quite as deep as others. The B&O A1 2nd gen is more neutral than the first A1 but is not stereo and has less deep bass than the A1.
Buy the B&O Beosound A1 2nd gen. It is rated higher for sound quality; the Teufel Rockster XS is no longer sold new.
