I be past 60 and for my age , my listening be worsen day by day that too after a surgery on my right ear . earlier I use to enjoy tv program -lrb- like Discovery , National Geography , HBO , Star Movies etc -rrb- almost till midnight . nowadays the tv program be become more and more garbled -lrb- to I ! -rrb- and could not enjoy the music and understand dialogue . I think I have to settle down for the rest of my life with this deficiency . I hear about wireless headphone which can be use for listen to tv program . I read all review about Sennheiser wireless headphone and the almost unanimous recommendation by user . earlier day it be difficult to get these world class electronic device in India . however thing be improve and to my surprise I could get this headphone slightly above the international price -lrb- r . 3,500 equivalent to about $ 75 -rrb- . I have use this for the past 2 week and I think I have make the right decision to go ahead with sennheiser . once I wear this and listen to tv , I be in new world altogether . the sound be so crisp and clear and I do not miss even one small whisper in movie and I be surprised how wonderful the normal mundane song be with lot of additional instrument , which be not hear earlier ! the range be quite astonishing . I live in a two storeyed concrete building and when I wear this and go to open terrace , I could still hear tv program -lrb- of course slight deterioration because of concrete structure -rrb- . within the house I can roam around all room and still do not have to miss anything . the battery last reasonably well -lrb- I have to change only once during the past 2 week -rrb- . I feel instead of rechargeable battery of rs120 or rs130 -lrb- which have almost identical specification -rrb- , this replaceable battery be better because we can always use nimh battery and separate charger , thereby ensure better reliability . overall I feel this investment be really go to serve I well .
