I am a big Libratone fan. I had the Libratone Zipp Mini at home, which I loved but it was with it’s the weight of 1.5 Kg to heavy. I choose to travel with the Libratone Too which I find with it’s 599 Gramm still too heavy but compared to all the other speakers it has for me the best sound. A friend of mine loves her UE Mega Boom 2 (550 Gramm). Another friend loves his Bose Soundlink (670 Gramm) which has a strong bass.
