Question: London-born violinist and conductor John Georgiadis is in charge here, exhuming and enlivening long-forgotten dance music from the pen of Josef Strauss. After he was bulldozed into joining the family dance-music business, engineer-trained Josef (1827-1870) proved to be the most industrious of all the Strauss family during the remainder of his short life. I reckon, having collected and listened to all the volumes so far issued in this Marco Polo Josef Strauss Edition, that inspiration and innovation did not always keep up with his gruelling work schedule. Reliance on the family formula seems evident in most of the items on this CD, where you'll find a spanking little march, three waltzes, a quadrille and a variety of polkas, heard best at concert hall volume so that subtle lifts in rhythm and phrase and the skilful orchestration are heard to best advantage.

Answer: Positive

Question: Good, sturdy platform for squatting under a barbell. Very firm. Laces are long enough to wrap around ankles, and back of shoe forms a fair notch to retain the laces and keep them from sliding up and off the shoes - would have been better had there been a rear loop. Shoes are better without the insoles because they put a spongy foam wedge under the heels. I replaced them with thin flat insoles from a pair of water shoes. One could cut the foam wedge and use the included insoles. There is no raised heel other than that foam wedge. They run true to size or slightly tight.

Answer: Positive

Question: These may work for some people, but for others like me, they're worthless. The fit was horrible and they did not stay in my ear. They also caused my Jawbone Prime to protrude far enough so that the front part no longer touched my face (which is required for their noise reduction circuitry to work). I threw these away and am now using the stock earbud with the ear hook.These are designed for people with a certain ear shape. If your ears don't conform to this shape (which is likely the case for many people), these will be useless. If you want these, I suggest buying from a local store where you might be able to try them on, or at least to return them without having to pay return shipping.

Answer:
Negative
