Yes. In general it's just muffled but once or twice we could really hear them though not enough to make out more than every few words (it was another T and a client). T and I had a good chuckle at trying to keep on with our own conversation while having another one punctuating. At one point I think the other T said something during a lull in our own and she actually made a fair point (with regards to my own session even though she was responding to her own client).
