What's on your mind?

Conrad • 12/17/2019, 2:17:43 PM Q. I am interested in purchasing this item for my back yard and place them about 150 feet from the house under some trees in a shaded area Would this work and how about transmitting sound from the house to these speakers? what would I require for all this to work?
Customer Service • 12/17/2019, 2:17:43 PM
Hello Conrad, The Bluetooth range varies depending on your device and whether it's an unobstructed path between your device and the speakers. 150ft should be doable if it is an unobstructed path. You can run these speakers using most smartphones and tablets.
Dave • 12/17/2019, 2:17:43 PM Can the speakers be linked together, if I wanted to have more than two?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Dave: Unfortunately you are limited to a single connection to the Bluetooth Receiver built into the main speaker. The main speaker has the stereo amplifier built in as well. The second or satellite speaker has to be hardwired directly to the Main or Sync speaker so you can have stereo right and left output. Only the signal between your Bluetooth enabled device and the sync speaker are wireless. We are working on a new technology where where the receiver may have a built in Bluetooth repeater to set up a second pair of speakers but it is still in the testing stage. I hope that helps answer your question TL/3699
John • 12/17/2019, 2:17:43 PM My Bluetooth connection is horrendous. I need to stand 5ft or closer with my Bluetooth device to connect. If the Bluetooth device is not pointed directly at the main speaker the connection fails. I bought these for use by the pool and measured what would be a 25ft unobstructed line of sight. What is the reason for the poor connectivity?
Customer Service • 12/17/2019, 2:17:43 PM
HI John: A couple of questions... Have you tried connecting to a couple of different devices with the same results? Have you tried plugging in the power supply to a different outlet? I am sorry you are experiencing a problem. We will run some tests with another Pair of Brown BTR-150 (like you own) to verify distance. TL/3736
Lorenzo • 12/17/2019, 2:17:43 PM Can you leave them on all the time?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Lorenz: Yes you can leave them on all the time. You can also unplug the Power Supply if there is better access to that versus the switch at the bottom of the Master Speaker. You might want to unplug them especially if your are not going to be using them for a longer period of time. When you plug them back in they will fire up right away. Regards TL/3799
Mike • 12/17/2019, 2:17:43 PM Are these speakers compatible with Sonos indoor speakers?
Customer Service • 12/17/2019, 2:17:43 PM
Hi Mike: I do not believe they are compatible with the SONOS system. These are Bluetooth wireless that have Bluetooth Receiver built in. It can only be controlled by a Bluetooth enabled device like a smartphone or tablet. The SONOS has its own proprietary Wi-fi connection where you set up a mesh network among all the SONOS devices that you utilize throughout your house. The more devices you add the stronger the network but no interface with Bluetooth. You can add the BTR-150 to your outdoors but it would be an independent system that you would control with your Bluetooth enabled device which can access or duplicate many of the apps like Pandora or Internet Radio stations that are part of the SONOS app as well. SONOS does not have outdoor speaker but people use many of our outdoor speakers with the combination of the SONOS Connect and our OSD Power Amplifiers. In this application you can drive more than a single pair of speakers. Our speakers also work well with the SONOS Connect Amplifier (up to two pairs can be connected to the Connect Amplifier). Also by adding the SONOS connect in this way it becomes part of the system and functions as another zone. And you have complete access to the SONOS network including the SONOS app and access to your network libraries. I hope that answered your question... TL/3810
