Who has a Hi-Fi stereo in the living room or in the living room knows very well when its sound performance is high, also thanks to the support of audio CDs or vinyls, able to give a unique sound, difficult to reach with other systems. audio playback. But the passage of time has rather obsolete stereo systems, also due to the growing diffusion of music through streaming services and music videos on smartphones; all the plants are so forgotten that they become real "knick-knacks", left to gather dust.
If we want to rediscover the sound of Hi-Fi systems with modern streaming services, in this guide we will show you how to connect your mobile phone to the Hi-Fi stereo in your home, so you can listen to any music in streamin g at the highest quality, using the smartphone as if it were a remote control .
Hear music from your smartphone on the stereo speakers
There are various methods to be able to connect a smartphone to the Hi-Fi system, it is up to us to choose the one that best suits our needs or that better integrates with our lifestyle.Bluetooth AUX receiver
The simplest method to connect the phone to the Hi-Fi stereo in the home is to use a Bluetooth receiver, so that you can send the smartphone audio to the speakers of the system without using any cables.
The receiver must be connected to the power outlet using the appropriate cable and to the Hi-Fi system via a simple 3.5mm Jack cable, using the socket identified as AUX on the system. Once connected, all we have to do is connect via Bluetooth to the receiver and start streaming music from apps such as Spotify, YouTube or Amazon Music. Obviously to be able to listen to high quality music we will have to stay close to the device (ideally within 5 meters).
One of the best Bluetooth receivers compatible with the AUX sockets is the AUKEY Bluetooth 5 receiver, which we can view here -> AUKEY Bluetooth 5 receiver (18 €).
Bluetooth receiver with RCA
If our Hi-Fi stereo does not have AUX input but RCA inputs (with the classic red and white plugs), we can use an RCA compatible Bluetooth receiver .
The connection is similar to when already seen with the AUX receiver: we connect the power socket, connect the red and white RCA cables to the respective sockets on the back of the system then connect the smartphone via Bluetooth to the receiver to transmit the audio. Also in this case we must remain close to the device in order to transmit the sound of streaming apps at the highest quality.
One of the best Bluetooth receivers compatible with RCA is the esinkin Bluetooth system, which we can view here -> esinkin Bluetooth system (24 €).
Optical Bluetooth receiver (SPDIF)
Do we have a large Hi-Fi system with a digital optical input and do we want to use it to obtain the maximum audio quality? In this case we will have to connect an optical Bluetooth receiver with SPDIF output .
The connection of this receiver is very simple: we use the Toslink optical cable included in the package to connect the SPDIF Out output of the receiver to the optical input of the system (usually referred to as Optical In, SPDIF In or Audio Digital In ), we set the necessary buttons on the receiver body (in this specific case the selectors will be positioned on RX and SPDIF ) and we connect the socket. Now all we have to do is connect our smartphone via Bluetooth to the receiver and start streaming music from your favorite streaming apps, taking care to always stay close to the device.
One of the best SPDIF-compatible Bluetooth receivers is the TaoTronics TT-BA09 2-in-1 Bluetooth 5.0 receiver transmitter, which we can view here -> TaoTronics TT-BA09 2-in-1 Bluetooth 5.0 receiver transmitter (29 €).
Chromecast and HDMI audio adapter
Another innovative method to connect the smartphone to the Hi-Fi system involves the use of the Chromecast, the Google HDMI dongle, which can be connected to any system via a specific HDMI audio adapter .
The Chromecast will be connected to the adapter's HDMI IN port, while the stereo system will be connected to the AUDIO OUT socket (via AUX cable or via AUX-RCA cable) or to the SPDIF OUT socket (via Toslink cable) on the other side of the 'adapter. Once connected all the audio cables and the dongle we supply electricity to both, we carry out the configuration procedure of the Chromecast to connect it to the home Wi-Fi network then we use the cast icon to transmit the audio of the streaming apps from the phone to the stereo, even if we are in another room or if we close the app (playback will continue on the Chromecast).
The best HDMI audio adapter that we can use for this purpose is the Ozvavzk HDMI Audio Extractor, which we can view here -> Ozvavzk HDMI Audio Extractor (17 €).
Echo Dot
The last method we recommend you try is the Echo Dot, Amazon's intelligent speaker also equipped with a 3.5mm AUX audio output.
To use it as a Bluetooth adapter and as an intelligent speaker via audio system, just connect one end of the AUX cable to the port on the back of the Echo Dot and the other end to the AUX input of our system.
In this way we will be able to connect the smartphone via Bluetooth and reproduce the sound of the multimedia apps and launch Alexa's voice commands to listen to music via TuneIn Radio, via Amazon Music or via Spotify Premium.

If you want to save money, you can also buy, instead of the Echo Dot, Echo Input to add Alexa to the stereo .
Conclusions
As seen above the home Hi-Fi system can still be exploited to the fullest, just add small devices to enable the Bluetooth connection, to enable voice commands and to make the system speakers available to any Wi-Fi device present in the home network (thanks to Chromecast and the HDMI adapter).If we want to add Wi-Fi and Bluetooth also inside the car radio, just read our article on How to add Wi-Fi and Bluetooth on each car .
If, on the other hand, we want to bring audio to every room through speakers, we invite you to read our guide on wireless speaker boxes to bring audio to every room or outside .
