As per the argument, despite claimed to have the same frame and technology as its successor did, the users of VA25 have to get the cups of their headphones replaced twice as frequently as in case of VA15. On the basis of this observation, it has been concluded that Verbal must have reduced the quality of ear-cups in VA25 to make up for additional cost of making it wireless. This argument can be weakened by bringing another factor into picture which might have led to the early wearing-off of the headphone cups. Option (e) says that sinceVA25 is wireless, it can also be worn while sleeping to reduce ambient noise. This means VA25 are used for longer hours as compared to VA15. This could be a factor responsible for the early wearing-off of the headphone cups. Thus, option (e) is the right answer.
