As a musician and a regular traveler between North America (110V for power outlets) and England (230-240V), my aunt needs an excellent speaker to listen to her classical music and opera on her laptop, because the laptop's built-in speakers have too poor sound quality.
What solutions can help my aunt? She has tried:
taking her speakers (that she uses now and purchased in the US) and a Voltage Transformer but this is too inconvenient and bulky.
purchasing USB speakers, but they suffer from too poor sound quality.
User 'cfinley' edited this question earlier, and suggested: a speaker system that she can take with her that works in both the USA and England without any Voltage Transformers and has good sound quality. What products would you recommend for her?
