Range Top, sound Well

The wireless headphones I bought so I can listen to music wirelessly in the building and few meters outside in the garden and satisfies the Sony MDR-RF865RK wireless headphones. You can hear without being interrupted and of course in the garden through 2 walls as still 30-40 meters distance far music itself by 3 or 4 walls. So I am fascinated by the Sony. The sound is to me, however dull and powerless. The detailed highs for a clear sound and a pleasant surround sound missing, something comes up no real listening pleasure. This may be the Sennheiser RS180 better, I had bought the day before, due to the laughable range (and at 189 euros) have, however, exchanged for these. But at home it's more, I keep the handset also. Who does not have great demands on the sound that these can indeed times listen in business.
