Bluetooth strength by aiming?

I can't quite get headphone coverage in the whole house. Is there a way to "aim" the iMac to get more signal strength in a particular direction? Many thanks~~

Are you using an Apple Bluetooth headset or a 3rd party version? What is the range in feet and number of walls the signal must pass through? What other wireless devices are in range? Any or ALL of those variables can contribute to loss of signal or interference. The more information you provide the more assistance we can give you in a solution.

Thanks for your answer. I knew most of that, but what I still don't know is whether the signal strength is greater in a specific direction coming off the iMac.

No the pattern is omni not uni directional.

Reduce potential signal interference

Because Bluetooth works by transmitting signals through the air, some things can interfere with connections. Avoid situations in which metal objects come between your device and computer. Don't put your computer under a metal desk or in a metal cabinet. Keep your computer away from cordless phone base stations, microwave ovens, and other electrical devices that operate on a 2.4 GHz bandwidth. Make sure that your device and computer aren't more than 30 feet apart from each other.

Sources of interference:

Microwave ovens: Using your microwave oven near your computer, Bluetooth device, or Wi-Fi base station may cause interference.

Direct Satellite Service (DSS) RF leakage: The coax cable and connectors used with certain types of satellite dishes may cause interference. Check the cable for damage and obtain newer cables if you suspect RF leakage.

Certain external electrical sources such as power lines, electrical railroad tracks, and power stations.

2.4 GHz or 5 GHz phones: A cordless telephone that operates in this range may cause interference with wireless devices or networks when used.

Video senders (transmitters/receivers) that operate in the 2.4 GHz or 5 GHz bandwidth.

Wireless speakers that operate in the 2.4 GHz or 5 GHz band.

Certain external monitors and LCD displays: Certain displays may emit harmonic interference, especially in the 2.4GHz band between channels 11 and 14. This interference may be at its worst if you have a portable computer with the lid closed and an external monitor connected to it. Try changing your access point to use 5 Ghz or a lower 2.4 GHz channel.

Any other "wireless" devices that operate in the 2.4 GHz or 5 GHz bandwidth (microwaves, cameras, baby monitors, neighbors wireless devices, and so on).
