A:AnswerAs implied in its title description, the LG XBOOM 700W 2.1ch Mini Shelf System with Built-in Subwoofer and Bluetooth®, Model # CM4550 is a Bluetooth enabled unit that can be paired with any Bluetooth device that supports the A2DP (Advanced Audio Distribution Profile) profile which is a Bluetooth stereo profile which defines how high-quality stereo audio can be streamed from one device to another over a Bluetooth connection. Although many products may have Bluetooth enabled for voice calls, in order for music to be streamed from one Bluetooth device to another, both devices will need to have this A2DP profile. If both devices to do not contain this profile, you may still be able to connect using a standard Headset or Handsfree profile, however, these profiles will not support stereo music...^IFV
A:AnswerClass II Bluetooth devices like your cell phone, Bluetooth Headsets and this LG XBOOM 700W 2.1ch Mini Shelf System with Built-in Subwoofer and Bluetooth®, Model # CM4550 have a range of 10m (33 feet). However, as you are aware from your own experiences, because many Wi-Fi access points use the same 2.4-GHz bandwidth as Bluetooth, they can often interfere with each other to the point where your Bluetooth device may not work properly. Most routers have an option to switch to the 5-GHz frequency. Other Bluetooth devices can also interfere with signals, so sometimes it's necessary not to be using several Bluetooth devices at once. Some cordless phones also operate on these frequencies, as do wireless speakers, cameras and wireless baby monitors. Some LCD monitors can also interfere, not because they use wireless technology, but because they can emit harmonic interference in the 2.4-GHz band, especially when you're using a laptop with the lid closed and an external monitor directly beside it. All electrical devices radiate RFs, but some do more than others. A microwave oven is a prime example of an unintentional RF radiator. If you turn on a microwave oven while using a Bluetooth device, it can interfere with the signal and, in some cases, block it entirely. Power lines, power stations and electrical railroad tracks can also emit enough RFs to disrupt Bluetooth. Some physical objects can interfere with RFs more than others. In the case of Bluetooth and Wi-Fi signals, the worst culprits are metal objects like filing cabinets, metal doors, refrigerators and even metal studs in walls. Plaster, concrete and bulletproof glass aren't as bad as metal, but can still interfere with Bluetooth signals, particularly if the objects are thick and the Bluetooth signal is weak. Water, bricks, and marble have a medium capacity for blocking Bluetooth...^IFV
