With Bluetooth installed on my PC audio server, instead of listening thru my DAC and tube amp, I optionally can stream audio to a pair of wireless Bluetooth headphones or to a small portable Bluetooth speaker, which I can move room to room.
The PC Foobar2000 server can be in another room, while I roam about at home untethered, but connected wirelessly to the server wearing a pair of Bluetooth headphones.
I control playback using my Foobar2000 Copilot Wi-Fi app running on my Windows phone, which I carry around in my pocket.
In Foobar2000, you can route audio out to any of the audio drivers installed on your PC, whether it be to your external DAC or to any connected Bluetooth audio device.
After pairing your Bluetooth headphones or speakers to your PC, in Foobar2000 go to 'Files>Preferences>Playback>Output>Device'. Your paired Bluetooth device should appear in the 'devices' drop down list. After you select it from the list, Foobar2000 will then send all its audio to that device.
See the figure below, where I'm selecting my connected JBL Flip 3 bluetooth speaker as my Foobar2000 audio output device. Make sure you first pair your Bluetooth device to your Windows PC, before entering the Preferences screen or the device will not appear in the Device drop down list.
I don't get the kind of enveloping audio quality that I experience when playing thru my DAC, tube amp, and bigger speakers, but it's not bad sounding at all.
But many times when I'm moving about at home with headphones on, I'm listening to some Internet talk radio show streamlining from Foobar2000, so I don't need super fidelity.
There are so many Bluetooth headphones and portables speakers available today at all sorts of price points, and some can sound really good.
If I want super fidelity from headphones, I put on a pair of my bigger, wired headphones like my Grado RS1's and connect them to one of my headphone amps. I still can use my Foobar2000 servers as an audio source.
So for my particulars, I usually go for smaller, light weight and comfortable Bluetooth headphones, that also don't cost a lot.
Some of the Bluetooth devices I use and like are :
This is a small sampling of Bluetooth devices -- from headphones to speakers to receivers/transmitters to PC dongles. Today there are a myriad of Bluetooth devices available to you, with new devices being introduced almost daily.
Mpow Bluetooth 4.0 AptX headphones -- about $37 on Amazon. Nice sounding and lightweight. Comfortable, not tight fitting on my head, very gentle. Also has an embedded microphone and so can double as a phone headset.
Puro Adult Bluetooth headphones -- about $150. See the Puro site. These headphones fidelity-wise sound better than the MPOW headphone, but they also fit tighter on my head, so aren't as comfortable as the MPOW headphones.
BlueAnt Ribbon Bluetooth AptX Streamer and HeadSet -- about $22 on Amazon. Very lightweight. The earbuds it comes with actually sound pretty good, but you can also change those and plug in another pair of lightweight earbuds or headphones you may have. I clip the streamer to my shirt. The streamer part itself has a microphone so you can also use this device as a phone headset. I especially like using this headset if I'm just listening to talk shows on Internet radio.
Sharkk Bluetooth 4.0 10 Watt Portable Speaker -- about $55 on Amazon. Good sound, has NFC and can double as a speaker phone.
Another Bluetooth Speaker that I use and can highly recommend is the JBL Flip 3 -- about $70-$80 on Amazon. The Flip 3 doubles as a speaker phone as well. JBL has recently come out with the JBL Flip 4 at about $99.
Other options if you want to use an existing pair of powered speakers or transmit via Bluetooth to an amp and then out to speakers, is to get a Bluetooth audio receiver, such as the HomeSpot NFC-Enabled Bluetooth Audio Receiver about $18 on Amazon. You can transmit Bluetooth from your PC audio server to the Bluetooth receiver...
Another Bluetooth receiver/ transmitter I use is the Indigo BTR9 -- about $23 on Amazon.
It you don't have Bluetooth on your PC or if you have had driver issues with supporting older Bluetooth hardware when updating to Windows 8.1 or 10, you can add a newer, small Bluetooth USB dongle to your PC.
One Bluetooth dongle I've used and can recommend is:
SoundBot SB340 Bluetooth 4.0 USB Dongle -- about $8 on Amazon. Supports all versions of Windows from XP to Windows 10. When paired with the Mpow headphones or Sharkk speaker, I've gotten at least 30-40 feet transmission ranges, but this also depends on the particulars of your place, like how many walls you may have to transmit thru.
If you need a greater range, there are also some high gain Bluetooth transmitters, some with advertised 100 feet transmission ranges. See Amazon.
