So you have a set of old wired speakers, and you’re wondering if there’s a way to convert them to wireless. You want to be able to stream music to them from your phone, laptop, or tablet.

Can I Convert Old Wired Speakers to Wireless?


You can convert old wired speakers into wireless by using add-on adapters or wireless rear speaker kits. You just have to plug the audio cable into the adapter, and from there you can connect to the adapter via Bluetooth.

Of course, it’s challenging to figure out which wireless audio adapter is right for your speakers.

Best Wireless Audio Adapters / rear speaker kits:

Here’s a list of our recommend wireless audio adapters. You can use these to convert old speakers into fancy wireless speakers. No need to buy expensive Bluetooth speakers!

1. Logitech Bluetooth Audio Adapter

2. Mpow Bluetooth Receiver for Music Streaming

3. UGREEN Bluetooth Audio Adapter

4. Bluetooth Audio Adapter for Music Streaming Sound System

1 - Logitech Bluetooth Audio Adapter

Logitech Bluetooth Audio Adapter

For most situations, this little Logitech Bluetooth audio adapter will do the trick. You just need to plug in the right audio cables and tap the button with the Bluetooth logo on it to start pairing with devices.

The Logitech Bluetooth audio adapter has two audio RCA ports and one aux (3.5mm) port. In short, it has the most commonly-found audio ports.

One interesting feature of this Bluetooth audio receiver is it can connect to two devices at the same time. It can also automatically pair to whichever device is within 15 meters.

Keep in mind, the device does require a power source, so make sure you have a free plug near your speakers.

2 - Mpow Bluetooth Receiver for Music Streaming

Mpow Bluetooth Receiver for Music Streaming

Here we have a very budget-friendly Bluetooth receiver. The ports are the same as the model mentioned earlier on (RCA and Aux), except this one uses a USB cable for power.

It also has a built-in battery that can last for 15-hours on a single charge. As for the Bluetooth, it uses 4.1 Bluetooth technology which supports a maximum of two connected devices.

In the box, you’ll find one 3.5 mm audio cable, one 3.5 mm to RCA cable, a USB charging cable, and the user manual. I think the most notable thing about this Bluetooth receiver is the USB cable.

3 - UGREEN Bluetooth Audio Adapter

UGREEN Bluetooth Audio Adapter

The UGREEN Bluetooth audio adapter also has RCA and aux ports. It works much the same as the other adapters, except for aesthetics. The Bluetooth receiver has a silver pairing button in the middle, with a sleek black finish.

The adapter also comes with a USB cable and a built-in battery. However, the battery doesn’t last as long as the previous adapter, at 200mAh, it only has about 8 hours worth of power.

If you have a speaker or stereo that has a USB port, then you can use that as the source of power, so you can always leave the Bluetooth receiver on.

One notable feature is it has A2DP and EDR which are technologies that enhance the data rate for a much cleaner and stable wireless connection.

Here we have another budget-friendly Bluetooth audio adapter. It’s got two RCA ports, one Aux port, and one AC power adapter.

What you need to know is this is a very bare-bones product. The kit doesn’t have any special features or an internal battery. It has to be plugged in at all times, which can be a bit bothersome.

On the other hand, the range is great (10-12 meters) and the product is light, looks nice, and performs quite well. It’s a good little Bluetooth audio adapter.

How to Convert Normal Wired Speakers to Wireless

The best way to convert normal wired speakers to wireless is by using Bluetooth audio receiver. The process will vary slightly depending on the speakers you wish to convert and the ports you need to use.

Most speakers, by far, use a simple aux cable or 3.5mm cable. Connecting the Bluetooth adapter via this method is super simple. You just need a female to female 3.5mm cable and you’re good. Most wireless speaker kits include the needed cable in the box, so no need to worry.

Now, if your speakers do not have an aux port, they probably use RCA ports. That’s where the above products will come into the picture. You need a Bluetooth audio receiver that has two RCA ports for audio.

Another option: some stereo systems will have an extra USB port that you can use with a USB Bluetooth adapter. These adapters are very cheap because they don’t have any other ports, it only USB. And USB can usually provide some power, so no need for external power.

Keep in Mind

A couple of pointers to keep in mind. For starters, most Bluetooth receivers require external power, so make sure you have space for an extra cable. While some have internal batteries, the charge usually doesn’t last for a long time.

Secondly, I don’t recommend going for the cheapest receivers. There are lots of off-brand receives that break down or run into issues after a few uses. It’s always best to go with a trusted brand, such as Logitech.

I also recommend looking for a Bluetooth wireless speaker kit that uses Bluetooth 4.1 or newer because it’ll save you the hassle of pressing the pair button every time. You just have to search for the device and connect, it will automatically remember the devices and switch to the appropriate one.

Go Wireless!

So now you know how to convert an old set of dusty wireless speakers into wireless speakers. The process is very simple but you do need to use the right adapter. For more powerful speakers, you might need to purchase a Bluetooth receiver with a Bluetooth amplifier. However, most simple Bluetooth receivers should work fine. That’s how you convert old speakers into wireless speakers.
