These really work well but the plastic snap together construction will break apart eventually. Also, these are not brass. Also, I used the headset to listen to Spotify on my laptop, and the audio quality for music was somewhat lackluster. Just received today. Size and fit were perfect. Just like another reviewer I too got 4 pod plugs instead of 5 like in the picture. I dont know that they will last the entire summer, but we can buy another pair in the next size. My fourth is now 16 and in the throws of this, reacts to everytihng! Built-In Microphone: For clear, hands-free calls. I?m not too picky .
