I have the headphones for a long time. For the undemanding listening to music in between you are exactly right. They are cheap and have a reasonably good sound quality. Exterior noise is well shielded and the design is been a while. For people who value good quality music they are less suitable. The bass is acceptable but not overly good. What I headphones but is highly anrechne that they survived a wash and still function properly.
Conclusion: For short on the bus listening music but OK for the perfect music Feeling not very suitable.
