6.What about the BASS performance of the EM5?

Open earbuds are born naturally with a wide soundstage, yet with the shortcoming of bass signals easily exposed. In order to minimize the loss of the bass signals, the EM5, being printed with 3D technology, is designed with acoustic tubes and bass pipes that can greatly keep its independence, to finally lay down the foundation of low frequencies with deeper extension. To acquire better bass performance, it is recommended to couple the EM5 with foam ear tips.
