A. Bluetooth Receiver
A Bluetooth receiver is one of the simplest and most affordable ways to convert your wired stereo, amplifier, or music system into a wireless one. All you need to do is connect the receiver to your existing system using an AUX or RCA cable. Once connected, you can pair your smartphone, tablet, or any Bluetooth-enabled device to stream music effortlessly. It’s a hassle-free solution to modernize your audio setup!
Disclaimer: Not all high-quality Bluetooth receivers are readily available in India, but you can explore options from international markets like the US or Europe. Brands like 1Mii, BluDento, FiiO, Audioengine, Auris, ifi, and Logitech are highly recommended.
i. Ugreen Wireless Bluetooth 5.1
| BT Version | 5.1 |
| Audio Output | 2 RCA, 3.5mm Aux |
B. Wi-Fi + Bluetooth Combo Devices
Devices such as the WiiM Mini and WiiM Pro are dedicated music streamers that can add wireless functionality to your existing sound system. In addition to Bluetooth connectivity, they support Wi-Fi audio streaming through technologies such as AirPlay 2, Google Cast Audio, DLNA, Spotify Connect, and more.
Additionally, WiiM music streamers can also bring these Wi-Fi streaming features to Bluetooth-only speakers and soundbars. Since they also function as Bluetooth transmitters, they can receive audio over Wi-Fi (from your phone) and wirelessly transmit it to other Bluetooth speakers or soundbars.
Another unconventional way to make a wired stereo system wireless is by connecting it to an older Amazon Echo device with an AUX output. This effectively turns your existing audio setup into a smart speaker. You can then use the Echo as a Bluetooth receiver for wireless music playback or stream audio over Wi-Fi directly from supported services such as Spotify and Amazon Music. Beyond adding Bluetooth functionality, this approach also brings voice assistant features to your sound system, making it a versatile and cost-effective upgrade.
And like any WiiM music streamer, Echo devices can also connect to Bluetooth-only speakers and soundbars. Once paired, you can configure the Echo to always route audio through the connected Bluetooth speaker or soundbar. But just keep in mind that this setup is limited to supported music services, primarily Spotify and Amazon Music.
1. Amazon Echo Devices (Launched before 2020)
i. Amazon Echo Dot (4th Gen) 2020 – Refurbished
| BT Version | N/A |
| Audio Output | 3.5mm Aux |
ii. Amazon Echo (4th Gen) 2020
| BT Version | N/A |
| Audio Output | 3.5mm Aux |
All Amazon Echo devices support audio casting through Spotify Connect and the Alexa Cast protocol. In practical terms, this means that direct casting is primarily limited to Spotify and Amazon Music.
However, Alexa can be linked with several other music streaming services, including Apple Music, TIDAL, JioSaavn, and more. Once linked, you can control playback entirely through voice commands. For example, saying “Alexa, play my Party Songs playlist on Apple Music” will start playing music from your Apple Music account. You can also take advantage of Alexa Routines to create custom automations. For instance, a phrase like “Alexa, I’m feeling sad today” can be configured to automatically play your favourite songs playlist.
There are a few limitations worth noting. YouTube Music cannot be linked to Alexa because Google does not support integration with Amazon’s voice assistant. Additionally, Alexa devices do not support Google Cast or AirPlay 2, which can be a drawback if you rely heavily on those ecosystems.
2. WiiM Music Streamers
i. WiiM Mini
| BT Version | 5.0 |
| Audio Output | 3.5mm Aux, Optical |
The WiiM Mini can cost close to ₹9,000 when imported into India. It supports popular streaming protocols such as Spotify Connect, TIDAL Connect, and AirPlay 2, making it a great option for users within the Apple ecosystem. It can also integrate with Siri and Alexa enabled devices for voice control.
However, one major limitation is the lack of Google Cast support. Since many Android users rely on Chromecast/Google Cast for audio casting, this can be a significant drawback. For that reason, Android users may want to consider other streamers that support Google Cast natively.
ii. WiiM Pro
| BT Version | 5.1 |
| Audio Output | Line Out, Optical, Coax |
The WiiM Pro costs around ₹20,000 in India, which is admittedly quite expensive. It’s best suited for those who already own a good-quality audio system and don’t want to replace it simply because it lacks Bluetooth or modern wireless streaming capabilities.
What makes the WiiM Pro stand out is its broad support for streaming standards. It supports AirPlay 2, Google Cast Audio, DLNA, Spotify Connect, TIDAL Connect, Amazon Music Casting, and more, making it one of the most versatile music streamers available. It can also integrate with Alexa, Google Assistant/Gemini, and Siri, allowing it to fit seamlessly into almost any smart home ecosystem.
C. Bluetooth Amplifier
A Bluetooth amplifier is an excellent option for those looking to upgrade their wired stereo or speaker system with wireless capabilities while also enhancing audio performance. This device combines the functionality of a traditional amplifier with built-in Bluetooth connectivity. You simply connect your speakers to the amplifier and pair it with your Bluetooth-enabled device to stream music directly.
