All-New Dual-Mode Bone Conduction & Speaker Audio | Thin 11mm Profile | Magnetic Base | TF Card Playback | Built-In Hook


The Speaker That Disappears Under Your Pillow: SluTune Q2

We have all been there: you want to listen to a podcast or white noise to fall asleep, but your partner wants total silence. Earbuds hurt your ears when you lie on your side, and playing audio from your phone is too tinny. Carter Alexander is solving this bedtime dilemma with the SluTune Q2, an ultra-thin speaker designed to slip seamlessly into your sleep routine.


Project Overview

Name and Creator: SluTune Q2 (Only 11mm Thin / Sleep Speaker with Bone Conduction Mode) by Carter Alexander.

What It Is: SluTune Q2 is a dual-mode sleep speaker that is only 11mm thick, thinner than two stacked smartphones. It is designed to be placed under your pillow or right next to your ear. It offers two distinct listening modes: a private Bone Conduction mode that transmits sound through vibration (so only you can hear it) and a standard Speaker mode for room-filling audio.

Status: The project is currently active and is scheduled to end on February 4, 2026.


Key Features

  • Ultra-Thin Profile: At just 11mm thick, it is engineered to be imperceptible when placed under a pillow, solving the "pressure pain" caused by wearing earbuds while side-sleeping.

  • Dual-Mode Audio:

    • Bone Conduction: Uses a transducer to send vibrations through your pillow or skull, allowing you to listen privately without disturbing your partner.

    • Air Conduction: Switches to a standard driver to function as a portable Bluetooth speaker for hiking or travel.

  • Implosive Sound: The campaign highlights a powerful acoustic design that delivers rich audio despite the slim form factor, a feature hinted at in the project's unique URL.

  • Standalone Playback: It features a TF (MicroSD) Card slot, meaning you can load it with white noise or audiobooks and use it without needing your phone nearby (great for digital detoxing).

  • Magnetic & Wearable: It comes with a built-in hook and a magnetic base, allowing you to clip it to a backpack or stick it to a metal bed frame.

  • Battery Life: Rated for up to 28 hours of playback on a single charge.


Rewards

  • Kickstarter Pricing: Backers can secure a unit for approximately $40–$55, a discount off the planned retail price.

  • Delivery: Shipping is estimated to begin shortly after the campaign concludes in early 2026.


Concept

The core concept is "Invisible Audio." The creator wanted to build a device that removes the physical barriers to sleep audio. By eliminating the need for ear-insertion (earbuds) and head-clamping (headphones), SluTune Q2 allows users to drift off naturally while still enjoying their favorite content.


Inspiration

The project is an evolution of the previous SluTune Q1, refined based on user feedback. The creator recognized that while "pillow speakers" existed, most were bulky, wired, or sounded terrible. The goal with the Q2 was to merge the fidelity of a good Bluetooth speaker with the stealth of a bone-conduction device, creating the ultimate "bedside companion" that travels with you in the morning.
