Alexa itself does not have an AUX input because Alexa is the voice assistant, not a single piece of hardware. Whether you can plug a 3.5mm cable into an Echo depends entirely on the exact Echo model and generation.
In 2026, the safest answer is: do not assume a current Echo has a 3.5mm AUX input. Amazon has removed analog audio ports from several newer models.
| Echo example | 3.5mm port | What it does |
|---|---|---|
| Echo Studio (2025) | No | Wireless audio / Alexa Home Theater |
| Echo Studio (2019) | Yes | 3.5mm + mini-optical line-in |
| Older Echo / Echo Dot generations | Some models | Often audio output, not input |
| Echo Input | Yes | Designed to feed Alexa audio to another speaker |
The important difference: AUX input vs AUX output
A line input lets another device send sound into the Echo so the Echo acts like a speaker.
A line output sends the Echo’s sound out to another speaker or amplifier.
The old version of this guide mixed these two functions together across several Echo models.
Does the current Echo Studio have AUX input?
The redesigned 2025 Echo Studio does not have a 3.5mm headphone/line-in port. Australian retail specifications list no 3.5mm headphone connector on the current model.
See the current Echo Studio product specifications.
This is different from the original 2019 Echo Studio.
The original Echo Studio did have line-in
Amazon’s own compliance documentation for the first-generation Echo Studio lists a 3.5mm AUX / mini-optical line-in.
Amazon’s original Echo Studio port specification.
If another guide says “Echo Studio has AUX,” check which generation it means.
Some older Echo ports were output-only
Several older Echo and Echo Dot generations had a 3.5mm connector that sent audio out to external speakers.
Amazon’s support specification for the Echo Dot 3rd Gen, for example, identifies its port as a 3.5mm Audio Output Connector.
That does not let you plug a phone into the Dot and use it as an analog speaker.
How can I play phone audio through an Echo now?
The normal method is Bluetooth.
Amazon’s current pairing process is:
- put the phone in Bluetooth pairing mode;
- open the Alexa app;
- choose Devices → your Echo → Device Settings → Bluetooth Devices → Pair A New Device;
- select the phone/device.

What if you need a physical audio input?
If wired analog input is a requirement, choose the speaker around that requirement rather than buying an Echo first and hoping it has the socket.
For a turntable, TV, CD player or PC with analog output, a conventional powered speaker, amplifier or receiver with clearly documented inputs is usually the simpler option.
Can Echo send audio to another speaker?
Bluetooth remains available on current Echo speakers, and some older Echo generations also provide physical 3.5mm output.
Modern Echo/Fire TV combinations can also use Alexa Home Theater. Amazon currently supports the 2025 Echo Studio and Echo Dot Max in multi-speaker Fire TV configurations.
Quick answer
Check the exact Echo model. The current 2025 Echo Studio has no 3.5mm AUX input, while the original 2019 Echo Studio did. Many older Echo 3.5mm ports were output-only. For most current Echo devices, Bluetooth is the normal way to play audio from a phone.
