Was skeptical at first due to the partial negative reviews. Can not confirm these reviews. I bought the speakers as an addition to my second TV, because the sound was not particularly. I was really surprised what came a sound. Opposite the TV sound increase of 500% Felt. Have you connected via the Headphone output. You have a full sound. Nevertheless, one should not expect a home theater system to purchase. There are very, very good speakers to complement on another device. The sound is well suited for normal Lautstärke.aber not for disco feeling. I can in any case recommend. There is no noise, hum, croak, or the like.
