Summary: I'm using these to listen to our TV; they are connected to the headphone out.
I bought them to replace my failed Sony MDR-RF4000K, but I'm not too sure if it was worth it. Compared to Sony, I can't really say there is *any* improvement, maybe only when playing GT5 - Sony had a very weird problem when sound was "travelling" between ears, possibly because it was dolby-encoded? Not sure, but these don't seem to have the same problem.
Pros: Sound fairly decent
Cons: Cut out when input volume is low; cups are too shallow for my ears, manual switch on
Summary: As others have commented, the buttons and their placement are horrible. They should have been raised slightly so they are not flush with the ear piece and they should have been spaced out slightly. Perhaps they should have used the rubbery type of buttons like the ones that are on a TV remote control to give the user some feel to promote confidence when trying to adjust the volume, surround sound or bass boost while they are on the listeners head.
Pros: Comfortable on the Head, Adjustable Headset, Great Sound, Decent Wireless Range, Effective Bass Boost.
Summary: My rating: 3/5 Would you recommend to a friend: No. A lot of reviews said this was a great product, so I bought it. I would not rate it above "okay". Cons: - To me, the product seems very frail / fragile. - You have to press a button to switch between "single mode" (using only one headset) and "multi mode" (using multiple headsets). This seems like a very obsolete approach to me: it should always be multi mode.
Summary: Hyvä äänenlaatu ja häiriötön signaali. Eivät toki pärjää kaikille saman hintaluokan langallisille kuulokkeille, mutta langattomien luurien parhaimmistoa. Rakenteeltaan perus Sennheiser-laatua ja sangassa riittää vääntövaraa varsin hyvin, eikä ylimääräisiä natinoita tai kitinöitä ole edes yrittämällä. Keinonahkainen pinnoite saattaa alkaa pidemmässä käytössä hiostamaan ja kuppikoko voisi olla aavistuksen suurempi.
Excerpt: Produto com muito boa qualidade de som. Infelizmente quanto ao alcance, fiquei triste, pois o objectivo era utilizar os auscultadores em toda a casa, e isso não é possível. O alcance anda a volta de 10 metros entre paredes. Para quem quiser utilizar os Phones para aspirar, por exemplo, não optem por este tipo, mas pelos rs 120,com transmissão por FM.
