True Wireless Stereo (TWS) Earbuds & Smart Charging Case with Touchscreen


The purpose of this topic is to discuss True Wireless Stereo (TWS) Earbuds that come with a Smart Charging Case featuring a touchscreen, which limits or eliminates the need for an iOS or Android app to access most or all features.


JBL Tour Pro 2

The first product to match this description is the JBL Tour Pro 2, which was released in 2023.

Smart Case Features

The smart case features a 1.45 inch touch screen, wireless charging, USB-C fast-charging, and magnets (to hold the earbuds inside the case and to hold the lid closed).

The smart case can be used for the following features:

  • Status bar displays Bluetooth status (off/on/connected), Spacial Sound icon (if enabled), and battery percentage of each earbud & smart case
  • Playback controls (:previous_track_button: :play_or_pause_button: :next_track_button:)

iOS/Android App

The JBL Headphones Android app is not open source, but it can be used without internet connectivity.

The iOS or Android app is required for the following features:

  • Personi-Fi personalized sound configuration (hearing tests)

    • Audio Mode (optimized for music and enabled by default)
    • Video Mode (optimized for low latency)

      • Equalizer
      • VoiceAware

I bought a pair of JBL Tour Pro 2 last year, and I love them! I hope that competition will eventually bring the ability to use a Linux computer to manage firmware updates and other settings, but that is probably not happening anytime soon. I’m just glad that I can access all of these features without an iOS or Android device, and they sound really good too.


JBL Live 3 series

At CES 2024, JBL introduced three different styles of JBL Live 3 earbuds, which will be available in Summer 2024.

The last TWS I owned were the Noble Audio Falcon TWS over 5 years ago, so seeing a touchscreen on charging cases is a huge surprise for me.

Do they work with the Librem 5?

Are they open source? Can they be verified? Do you trust them?


Yes, the JBL Tour Pro 2 earbuds work with the Librem 5; I’m using them right now to listen to an internet radio station using the Shortwave flatpak.

Are they open source? Can they be verified?
No, I don’t think so.

Do I trust them?
They have no network connectivity features, so I don’t feel like I need to trust them. What malicioius things could they even do? I can’t think of anything.

I borrowed a degoogled phone from a friend and verified that the JBL Headphones Android app can be used without internet connectivity, whereas the Sony Headphones Android app requires an internet connection when you click the buttons to agree to TOS and Privacy policy, which makes me distrustful of Sony products.

Besides the PineBuds Pro, which do not have a touchscreen-enabled smart case, there aren’t any other open source TWS earbuds yet. If Purism decides to make their own TWS earbuds, I will absolutely buy them.

But even if there is a nice free software linux app for controling them, the touchscreen-enabled smart case is a game-changer for convenience and usability that makes for a platform-agnostic product. That is what should be the focus of companies like Purism when making products like TWS earbuds. If a non-linux user were looking for such a product, the requirement for a free software linux app would be a strong deterrent.


Can you elaborate on what connects to what and how?

Even without internet connectivity, a comprehensive investigation of the security and privacy risks would have to consider what RF transmissions are involved.


I’m not an expert here, just a user. If my understanding is correct, TWS earbuds only connect to each other, the charging case, and the transmitting device - all using Bluetooth; there is no Wifi involved.

Bluetooth itself seems to be greatly lacking in security. Using Bluetooth devices is inherently risky, to an extent, and it’s a risk that I currently accept.
