This place is incredible. Definitely one of the best museums I've been to recently. The venue itself is gorgeous as well. As a hack cellist, this place was a delight. The headset is pretty well integrated into the exhibit as well--most times I find museum headsets annoying and not worth the extra cost or hassle, but the musical accompaniment for each exhibit was great. The experience room where you can try out instruments was probably my favorite part.
My only main criticism is that some of the exhibits basically seemed like ads for the instrument manufacturers. For example, the Steinway exhibit talked for three paragraphs about the superior quality of Steinway pianos. The Fender exhibit was the same way and so on.
