Basso's isolate just as well as the Tenore's. Housing is bigger but fits in the ear canals with no issues.
The Basso's will give a more colored/fun presentation over the GR07's. This doesn't mean you won't get the details in the music. It's just more engaging to listen to. If you like the GR07's, the Tenore's might be a better phone to get. Compared to the Z200's, those are in another league. The bass is overbearing and can get fatiguing after a short while. All the other phones are better balanced to which I mean nothing is boosted as much as the Z200's.
Someone asked about the realism of acoustic instruments and I'd have to say the Basso's and Tenore's pass this test very nicely. Orchestral music sounds a little better with the Basso's because of the added bass and larger stage. Singer/songwriter with single acoustic guitar sounds a little better on the Tenore's because it sounds more forward and there's a little more zip in the plucking of the guitar strings.
