Individuals share music through portable audio devices (100) that synchronously play music by transmitting music signals from one device (unit A) to the other (unit B). Upon request, other individuals can join such a sharing group as a member, and these new members can either be accepted automatically, or through voting by existing group members. So that members of a group can converse, the fraction of ambient sound admitted by the earphones of the portable device (100) can be manually set. In order to enhance the enjoyment of the music, wearable transducers (240, 250, 260), such as light emitting diodes, respond to signals related to the beat of the music. Signals can be automatically generated, or manually specified, and signals thereafter stored for playback with the music to which it is related. Wearable transducers associated with individuals at a large music event can be set to receive common signals such that the transducers (240, 250, 260) respond in synchrony with one another.

A control message transmitting/receiving method in an MBMS-supporting mobile communication system. In the present invention, an RNC periodically transmits control messages related to MBMS RB setup to UEs. Thus, although a UE initially fails to receive an intended MBMS service, it can set up an MBMS RB by receiving a related retransmitted control message. Also, the RNC periodically provides information about ongoing MBMS services on a cell basis so that a UE can decide whether its requested MBMS service is in progress and request information required to set up an MBMS RB for the MBMS service to the RNC by individual signaling.

A headphone and method for allowing manually controlled reception of ambient sound by a user. More particularly, the invention relates to a headphone for listening to an audio signal while allowing varying amounts of ambient sound to the user. In one aspect, the headphone comprises a manually-controllable physical characteristic that controls the amount of ambient sound accessible to the user. The physical characteristic can be sound ports that can be opened or closed. In another aspect, the headphone can comprise a microphone receptive of ambient sound, wherein the user can control the proportion of sound that comes from the ambient sound or the audio signal. The microphone can be part of a noise cancellation system.
