    Great if and when they both work

    I initially purchased 2 pair, they were great out of the box. At least until the first pair quit pairing together after about 3 months, then 2 months later they quit charging. So I fired up the second pair and they made it a whopping 2 months before they quit pairing together, still charging but it's not hardly worth it. And support is not something that I've been able to find here on their website.

    This is my 3-4th order from RS, including the awesome Hyphen (I want them to die so I can get Hyphen 2 but they just keep rolling year-after-year.

    For this order of a Tau & Edge complete kit, everything was great. Good sale, fast shipping, correct order. My only concern is either the Edge sticks out from laptop when configured to work both vertical and horizontal, or I installed wrong. I can see how to have it flush and not protruding if I wanted only one of those options, but to have both it is trade-off. It’s not a major issue and it appears to come off if I decide to change it. Or maybe I should look at the coming Edge Pro and see if that one solves this issue. Overall, very satisfied with RS stuff. I want everything they make! What’s next?

    I got the hyphen earbuds and liked them so when the hyphen 2 earbuds came out I jumped on the Kickstarter immediately. They're my absolute favorite earbuds. Honestly the only negative thing about them is that I've misplaced mine and they're sold out. I hope they make more again soon because I'm lost without them! Sound is perfect. Actually hold the charge And the fit is incredible.

    HYPHEN® 2

    The Best Wireless Earbuds at an affordable price.

    We have designed HYPHEN® 2 with components used in earbuds that cost three times as much. We then added new technologies never seen before on other wireless earbuds, and cut out the middlemen to make them truly affordable.

    Pocket sized Charging Case

    HYPHEN® 2’s case has undergone months of real-world testing to achieve the best shape and size needed to be truly comfortable in your pocket.
    Extensive work by our engineering team allowed the case to be packed with technology, while retaining its portable size. Wireless charging, gyroscopic sensor, and an industry leading battery life didn't come at the expense of compactness.

    QI Certified Wireless Charging

    Still absent from most models on the market, wireless charging is the future of portable devices. HYPHEN® 2 features Qi wireless charging without compromising in size. After AirPods®, it’s the smallest model to feature this technology.

    Premium audio quality

    HYPHEN® 2 guarantees a truly immersive listening experience, thanks to:

    aptX™ Audio
    aptX™ technology compresses and decompresses audio in order to transmit the audio waves over Bluetooth without losing any quality. This process ensures you get the most out of every sound you hear through your HYPHEN® 2.

    6μ Composite PEEK Driver
    Our 6μ polymer composite PEEK driver provides a full range listening experience, satisfying even at lower volumes.

    FHS™ eartips

    The inner foam precisely adapts to different ear canal shapes for the best fit and isolation.

    Hard Silicone Canal
    HYPHEN® 2's custom designed silicone shore delivers accurate audio quality, with thick bass and crystal clear mid-high frequencies.

    Soft Silicone Dome
    The soft silicone layer provides comfort and grip, so you can listen to music for hours at a time.

    anti pressure holes

    Anti Pressure Holes eliminate the annoying Stethoscope Effect, allowing you to keep your HYPHEN® 2 on all day long.
    Additionally, they provide the needed airflow to the driver's diaphragm, further enhancing the audio delivery.

    Full touch control™

    HYPHEN® 2 gives you a level of control over your phone never seen before, with 8 different commands.
    Our Full Touch Control™ technology will let you stay off your smartphone for most actions.

    Qualcomm® Chipset

    One of the most stable and compact Bluetooth 5 chipsets ever made by Qualcomm, the worldwide leader in chipsets, with 35 years of experience.
    A powerful tri-core processor architecture ensures secure and instant connection, supports aptX™ audio delivery and optimises battery consumption.


    A suite of algorithms works on the transmission and receiving paths of voice calls to deliver optimal voice quality. It suppresses background audio such as ambient noise, road noise and other people talking, to deliver a clear call quality.

    4 microphones

    Each HYPHEN® 2 features two microphones facing opposite directions.
    The cVc™ algorithm analyzes outside noise along with your voice to emit cancelling sound waves. The result is an isolated voice, as if you were calling from a quiet room.

    IP55 dust waterproof certified

    HYPHEN® 2 has been certified for resistance against dust ingress and water jets from any direction, allowing you to run under the rain without having to worry about your earbuds.
