不過看了一些評論之後，覺得這個線控似乎中看不中用
以下這段話節錄自ThreeGMobile.net對W900i的評論
While Sony Ericsson prepared integrated handsfree control HPM-80 for W900i. The handsfree incorporates the FM radio. This arrangement rules out the RDS feature. You cannot set to store radio stations automatically and it is harder to search a radio station. In return, you can control the volume, song list, forward and backward from the handset without referring the phone. I did not feel this arrangement is good especially scarifing the RDS radio. The control and key is not comfortable. No clip is prepared to hold it on the clothes. The remote display does not support caller number displayand making the it useless. I think the actual users have to spend sometimes to overcome that feeling.
這個HPM-80雖然可以用來聽廣播，但是卻不能記憶電台位址...
也沒有一個小夾子可以固定在衣領...
線控上的螢幕也沒辦法顯示來電者的號碼...
看來只能用來控制音量及選曲了...
如果真是如此的話
那就顯得HPM-80很雞肋了...
