Property me because of a review ordered the Wavemaster Pure and Philips SHE9800 and come to the following conclusion: The Wavemaster has unpacked from the already opened packaging a loose connection, sounds more center-weighted like a PC satellite speakers, if it is operated without a subwoofer when the button does not sit deep in the ear canal. I use the smallest article, the bass is overdone and wafts like a disco cellar, without the midrange and treble reproduction is improving markedly. Overall he is extremely sensitive to the fit in the ear, you will be able to elicit the same sound he hardly 2 times, probably you will even need to readjust during running. The Philips contrast sounds much more pleasant, bass is plentiful, about the fundamental range, however, is under-represented, which makes sound Männerstimmen something unnatural. Too much volume one should not expect the Philips, he distorted. My reference, a Sennheiser HD650, was also from the "High End" (haha!) - Philips can not be achieved approximate and showed how much sound quality is even rauszuholen from a smartphone. Unfortunately, I do not want to make on the road to Mickey Mouse me with that thing.
Overall, I would like to express a sneaking suspicion that a good portion of the reviews, especially for Wave Master, have been written by let's say ardent admirers of the manufacturers whose objectivity leaves to be desired, and should be considered with healthy skepticism. What is thrown around here superlatives (several times "Genial", "Top", "Super", "Excellent", "tip ..."), which should make the attentive reader already suspicious.
Of course it is also conceivable that all different ears and listening habits have, therefore: Again help again just trying out and possibly return!
