PEBBLE, Conveniently Bringing Music Back to Life


At last, an audio amplifier that actually works with your phone without all the hassles. Battery-free. Ultra-light. iPhone-compatible.

About this project

Upgrade your mobile music listening experience forever, period.

The Music Revolution – Streaming high quality videos & audio on mobile devices are high in demand, so we created the ultimate sound device to meet that demand. PEBBLE is the first light-weight, compact amplifier designed to give you the highest sound quality without limiting your smartphone functions.

As audio and video technology advance, streaming videos and music on mobile devices has become mainstream. However, most portable devices are not designed for streaming high quality sound. In the era of mobility, do you really want to carry a heavy amplifier around? No, and neither do we! PEBBLE produces the same high definition sound as a heavy duty, high end amplifier, but it fits in the palm of your hand.

Before vs. After Sound Quality Experience

Designed for iPhone lovers

Does your portable amplifier prevent you from controlling your media on your iPhone? Is the microphone on your headphones and your amplifier not compatible? Is your current amplifier bulky, uncomfortable or distracting? If you answered yes, then PEBBLE is the solution for you!

Since the introduction of smartphones, streaming audio and videos on the go has become the norm. We have the convenience to stream sound anywhere in the world, but the sound quality is often compromised for convenience and portability. Moreover, many smartphone functions won’t work with most of the current portable amplifiers in the marketplace. At TEICNEO, we believe the most important task of a phone is to communicate. With PEBBLE, we provide the perfect solution to that problem. Light, strong, yet capable, the PEBBLE is world’s first portable amplifier that allows you to use the built-in microphone of your headphones to control playback of your media, as well as make and receive calls while in use.

Who is it for?

Key Features

PEBBLE is battery-free, allowing you to access your music easily. Life with high quality sound is just this simple.

PEBBLE is fully compatible with all of your iPhone functions, gives you quality sound while still weighing less than 1 ounce! Despite its size, PEBBLE is as resilient as a natural pebble, making PEBBLE not only the lightest amplifier, but also the most durable and stylish one.

Simplicity! PEBBLE is designed for your convenience. You simply plug it into your smartphone and go. Its unibody designed without any buttons improves the overall user experience and minimizes the potential of wear-and-tear from moveable parts. The smooth outer surface is built from high quality and durable metal chassis to give it both the strength and appearance of a pebble. The naturally strong structure not only provides a beautiful appearance, but also protects your amplifier.

Most portable amplifiers are limited to just audio playback. However, PEBBLE is the world’s first portable amplifier that is compatible with your earphones. You have full control of your media through the mic box on the earphone wire, and if you receive a call while in use, simply speak through the mic on the earphones.

With the newest audio chip module, the PEBBLE provides the highest sound quality with Hi-Res Audio.

One of our stretch goals is to develop an app exclusively for PEBBLE. Some of the anticipated functions include a media player, playlist editor, and equalizer. This app will also have updates when Apple releases new software updates. You will be able to enjoy the latest apps, compatible with iOS, and of course, PEBBLE can still be used normally without the app.

Technical Specification

By using the newest audio amplifier module certified by Apple, you will be able to enjoy your music without any hassles. Simply click the button to control your media, and pick up phone calls with your original headphones.

The new integrated audio chip gives PEBBLE the ability to playback at 24-bit, or 48 kHz to 192 kHz sound, making it easy to enjoy high-resolution sound anytime, anywhere.

We used the same highly advanced metal forming technology used in aeronautical space shuttles. By applying this sophisticated metal-forming technology on a much more intricately small scale, we successfully achieved the shape, the texture, and strength of a natural pebble. Furthermore, each PEBBLE is individually formed to embody the uniqueness, natural beauty, and strength of a natural pebble.

Everything needed for performing high quality music is inside the compact PEBBLE.

Fully supports iOS devices (with Lightning input) for direct media control and call handling functionalities.

We designed PEBBLE to resemble its natural state, in serene beauty and strength. Therefore, PEBBLE symbolizes the purest sound that washes over our ear and touches our heart.

Risks and challenges

We currently have fully-functional prototypes ready and is in the process of undergoing product usability testing. In the past year, we have overcome numerous technical difficulties, ranging from applying a new metal technology (to form the pebble shape) to securing a more powerful chipset to give our backers the best performance possible. In order to ensure Pebble’s full compatibility with Apple devices, we have undergone the MFi Certification, Apple’s official (“Made for iPhone/iPod/iPad” / certification) process. As with any certification process, there are always risks. However, with our team’s extensive expertise in hardware optimization and past successful Apple certification experience, we are expecting the certification to be complete by April. With a MFI-certified Pebble, backers can focus on the music experience and not have to worry about device incompatibility issues.

With hardware projects, there are always potential risks in shipment delays due to inefficiencies in supply chain management. We are currently working with a number of qualified and experienced vendors that are within a close vicinity of our manufacturer to prevent manufacturing downtime or key component supply shortage. Therefore, we are confident that we will achieve the milestones set out in this project.
