The AIYIMA S400 v1 offers impressively good sound for its price, but its major flaws significantly undermine the overall experience: the speaker relies heavily on the remote for accessing key features, yet replacement remotes are not available, and AIYIMA refuses to provide IR codes for universal remote programming, leaving users permanently locked out of certain functions if the remote is lost; combined with weak customer support and lack of parts availability, it feels like a product designed without consideration for long-term usability, making it a risky buy despite its strong audio performance.
