Sound quality is very good and it appears solid and well made. The noise cancelling function works to minimise background noise but it will still amplify sounds from the diaphragm (so scratchy clothes or moving it around may generate loud noises). The operating system was simple to use and I found that the combined half diaphragm / half bell setting was the clearest for routine cardiac anaesthesia use.
