You see , this is what I hate about rreactiongifs . It just plays into the male fantasy <| sep |> Call my parents . I can ' t handle that responsibility . <| sep |> I have Titan 5 same body , but different sound . Here some of my thoughts Cable noise might be an issue , if you don ' t secure cable or wear IEMs over ear . I only could reproduce cable noise when jumping . Yes , they are heavy . I am totally fine walking long distances with them , however running might be issue . Consider wearing them over ear , if you feel pressure on ears . Since they are inear and have better isolation , outside sound will be mostly muted . I would not recommend them if you running on street . Consider your safety . Before having Titan 5 , I owned Sennheiser sport for running PMX 685 i . They were comfortable and since they are ON ear , sweat and longer running sessions were not an issue . Outside sound also gets in easier , so it ' s safer . Sound was actually good , overall balanced sound . Very like sennheiser . I ' d recommend hearing to those before you decide . Anyway , I gonna try to run with Titan 5 today and let you know my impression .
