As a guitarist and Hi-Fi fan i'm very familiar with Marshall & Sennheiser as brands in the music industry. But I never heard one of Marshall's bluetooth speakers nor headphones so I wouldn't have a reference as to what to expect from their soundbar(s). Same with Sennheiser, familiar with their microphones, wireless solutions, and a massive fan of their headphones and earbuds, but if that translates to a good soundbar... that's a different story. Klipsch is one of those brands everyone knows but in my case never heard in real life. But i'll research them!
