EOLE Beta

Announcing our High-Definition Bluetooth module

 

Hello everyone,

 

Lucas here, and I hope you are doing well 🙂

Today, I am proud to announce for the first time EOLE, our High-Definition Bluetooth module!

 

 

What is EOLE?

 

 

EOLE is a 3.5 cm diameter elegant aluminum medallion that will allow all our ODS earphones to be used wireless. Baptiste was originally inspired by pocket watches when conceiving EOLE and wanted something discrete and simple. Following our previous products names that come from various mythologies, we decided to name it of the name of the famous Wind God to symbolize its wireless technology.

EOLE was developed mechanically and electronically at the end of 2017, but we put its development on hold to concentrate all our efforts on the VK-X. Today, I am happy to announce that we just finished the assembly of the first 80 Eole Beta units at our workshop.

 

 

What are EOLE’s main features?

 

 

Fully Compatible with our ODS range of in-ear headphones

Thanks to our MMCX connectors standard, EOLE will be fully compatible with all our ODS in-ear headphones (ODS-1, ODS-D, ODS-1 Essential, ODS-D Essential), but also with all MMCX earbuds of the market. A list of compatible earphones will be published later on.

A Travel Companion

With a 10 hours autonomy (8 days in sleep mode!), EOLE will connect by Bluetooth with both iOS and Android devices to accompany you throughout your day whether you want to listen to your music or to take calls directly thanks to its built-in microphone.

High-Definition Sound

EOLE will be a High-Resolution Bluetooth module that features the following major audiophile Bluetooth codecs: Aptx HD, Aptx, AAC. You might be surprised by its sound quality: our 24 bit DAC (Digital to Analog Converter) is likely to be superior to your device’s DAC when used wired, thus offering you an impressive listening experience.

 

 

When will it be launched?

 

 

EOLE will be officially launched in 2019, but we decided with Baptiste that we would offer for the first time a discounted and limited Beta edition to our users, thus allowing us to collect feedback on the product before its public launch. We produced 80 EOLE Beta modules for that purpose, that will be available on our website for private orders on Thursday, December 6th. Those modules will be made available alone (in case you already own one of our ODS earphones), and in bundles with our ODS-1 and ODS-D earphones.

 

 

The 80 private beta orders will allow you
to benefit from 20% to 35% discounts 
on EOLE
and its bundles’ future public prices.

 

 

What is an aëdle Beta product?

 

 

By ordering a Beta EOLE module, you can benefit from a discount and be the first to own our new product, and enroll in our EOLE Beta program. We will ask you to share your feedback on EOLE through a dedicated form in the next months to help us do minor adjustments and guide our communication around it before its public launch.

 

 

 

Please let us know if you have any question or comment, by posting it on this article or by contacting us by email at baptiste@aedle.net or at lucas@aedle.net! I will publish next week a new article that will let you know more about EOLE.

 

I wish you a great day,

Lucas

BLUETOOTH AUDIO STREAMING

Part 1 – Why Bluetooth 4.2 over 5.0?

Hi everyone,

We have received an overwhelming number of responses concerning the VK-X and I would like to personally thank you for your support and commitment to our project.

Today I am going to the take the time to respond to a question that has come in a number of emails.

 

Will the VK-X have Bluetooth 5.0?

 

The answer is NO for several reasons. It will, in fact, be 4.2 and it will indeed have the same efficiency of that of 5.0 Bluetooth (that is to say compatible with Bluetooth 5 devices for audio streaming), but I am going to take the time now to explain why we made this choice.

When the Bluetooth Special Interest Group (SIG) announced the creation of Bluetooth 5.0 in 2016, there was a lot of buzz generated for this seemingly major advance in wireless technology. What is interesting, however, is to see at what point certain parties including media outlets and invested companies have questionably manipulated this information for their benefit.

Here are the ‘ameliorations’ proposed by Bluetooth 5 technology that you see everywhere:

  • Range x4
  • Throughput x2

 

What we don’t see or what is not often stated is that, firstly, one must choose between the two ameliorations. It is one or the other in relation to the radio chosen by the system integrator (“PHY”). On the other hand, these ameliorations are exclusively for BT LE (Low energy products), which is technology dedicated to the internet of things with a very low energy consumption. The Bluetooth low energy sends small packets of information and isn’t really adapted to continuous music streaming.

Bluetooth Classic is the technology used for audio applications, via a superieur bandwidth (3 Mbps in theoretically 2.1 Mbps actually) and a profile dedicated to audio applications “A2DP” (Advanced Audio Distribution Profile)

 

In all fairness, to do justice to the BT 5.0, Bluetooth 5 nevertheless sets a very solid foundation for the arrival of a new standard of audio streaming, with reduced energy consumption, to achieve a theoretical bit rate of 2 Mbps, effective around 1.4 Mbps.

Nevertheless, there are several problems to be resolved, via the creation of a new profile (like the profile A2DP used for audio streaming):

  • Recomposition of segmented data packets
  • Management of asynchronous data packets

 

 

To resume,

 

  • Audio streaming via Bluetooth is done via the A2DP profile, managed uniquely by Bluetooth Classic
  • The bandwidth of Classic Bluetooth is higher than the bandwidth of Bluetooth LE (5.0).
  • BT LE 5.0 is a preparation for the future of audio streaming that consumes less energy and yet uses enough bandwidth for high-quality audio streaming

 

 

In my next article about this topic, I will develop more. I will explain more about Audio Formats, Codecs and Bits. Please do not hesitate to post your questions: I will be happy to answer!
