DELIVERY The delivery is excellent: Both cable (digital and analog jack) are included, as connection options for non-German power grids, a graphic basic instructions are included in paper form, a detailed manual on CD. Finishing and comfort: The are outstanding and high quality. The headset itself weighs with the inserted into the earcups AAA batteries just 330 grams and sits very comfortably and pressure-free even in continuous operation on the head. The charge and the main station is about 24 cm high, simple yet processed visually appealing. The headphones can be set up in both directions for loading and drop, total an eye-catcher. OPERATION: Both on the charging station and on the right side of the headphones you can activate or deactivate both volume and switchable bass and Sorround functions (the latter in two stages). Also, the general switching on and off is possible in each case here. Important: Even when the headphones resting this can be achieved directly without any problems. In my 70 square meter apartment, I have excellent reception everywhere. ANSCHLUSSMÖGLICKEITEN: The terminals (digital or analogue) are not automatically recognized, you have to specify this by means of switches on the rear of the charging station. So but you can connect two devices easily and switch between them, in my case, my Onkyo digital receiver, the TV and Blu-ray player appeals, and analog through 3.5mm jack my PC. KLANG: About the digital connection that is absolutely low-noise, analog with me not (but due to my PC and the integrated sound). After adjustments in sound of the RS 175 delivers a total of very good results. Home theater comes across perfectly, with audio CDs I often lacked that certain something when it comes to sound heat. To me it is here often too bright and brassy ... The adjustable functions bass and surround in two stages for me are sometimes vain (for audio CDs), at home theater or normal television makes sense. Definitely an added value in the latter cases. CONCLUSION: In terms of quality and processing an excellent headset that performs very well wirelessly, can appeal to two audio sources and its price is more than worth it. The slightly imperfect sound intensity at pure audio (CD or uncompressed digital) in my eyes will cost a star.
