    RayNeo’s product pages list a different connectivity spec depending on the model. RayNeo X3 Pro lists Bluetooth 5.3 alongside Wi-Fi 6. RayNeo iO, the newer everyday AI glasses, lists Bluetooth 5.4 with Apple MFi certification. GT, GT Max, and the Air lineup (Air 2s, Air 3s, Air 3s Pro, Air 4 Pro) don’t list a Bluetooth version. They connect to a phone, tablet, or laptop through a wired USB-C cable.

    A Bluetooth version number is a standard’s feature level. It doesn’t by itself tell you how a particular product pairs, how long it lasts, or what it can do wirelessly. The rest of this guide covers what each number refers to and why two RayNeo product lines don’t list Bluetooth.

    RayNeo’s Bluetooth Versions, Model by Model

    The table includes X2, RayNeo’s previous-generation model, which is listed as sold out on RayNeo’s site. It’s included as a baseline, not a current purchase option.

    Model Bluetooth Other wireless How it connects
    X3 Pro 5.3 Wi-Fi 6 Wireless pairing through the RayNeo App
    iO 5.4, MFi Certified None listed Wireless pairing through the RayNeo App
    X2 (out of stock, previous generation) 5.2 Wi-Fi 5 Wireless pairing, plus the bundled Bluetooth-connected RayNeo Ring controller
    GT Not listed Not applicable Wired USB-C (DisplayPort Alt Mode)
    GT Max Not listed Not applicable Wired USB-C (DisplayPort Alt Mode)
    Air 2s / Air 3s / Air 3s Pro / Air 4 Pro Not listed Not applicable Wired USB-C (DisplayPort-compatible)*

    *GT and GT Max’s product pages use the term “DisplayPort Alt Mode.” The Air series pages describe the same kind of USB-C video connection as “USB-C video output” and “DisplayPort-compatible.”

    X3 Pro and iO are the two RayNeo models that pair wirelessly with a phone over Bluetooth. The others plug in for video and, depending on the model, have their own audio hardware, covered below.

    What the Standard Added in Bluetooth 5.2, 5.3, and 5.4

    Each new Bluetooth Core Specification version adds capabilities to the standard. Whether a given product uses them depends on its chipset and firmware, and often on the connected phone as well. The Bluetooth SIG describes the additions in its 5.2 feature overview, 5.3 feature enhancements, and 5.4 technical overview:

    Bluetooth version Used in Added to the standard
    5.2 X2 LE Power Control, foundational pieces of LE Audio, Enhanced Attribute Protocol
    5.3 X3 Pro Connection Subrating, Channel Classification Enhancement
    5.4 iO Encrypted Advertising Data, Periodic Advertising with Responses

    These are capabilities the standard defines, not test results for RayNeo’s products. RayNeo hasn’t published which of them its firmware enables, and the practical benefit for pairing, reconnection, interference, or battery life depends on both ends supporting them and on testing conditions. A higher version number alone doesn’t show that one RayNeo model pairs more reliably or lasts longer than another.

    Does a Higher Bluetooth Version Mean Better Audio?

    Not automatically. The version sets what a chipset can support, but which audio codec is used (standard SBC, AAC, or something higher-fidelity) depends on how the manufacturer implemented it and what the connected phone supports. RayNeo hasn’t published a codec list for X3 Pro or iO.

    iO’s spec sheet lists MFi Certified alongside its Bluetooth 5.4 radio, which X3 Pro’s spec sheet doesn’t. MFi is Apple’s certification program for accessories. RayNeo hasn’t detailed what it covers for iO, so treat it as a sign of Apple’s accessory program participation rather than a guarantee of a specific feature. It doesn’t apply to Android phones at all.

    Why GT, GT Max, and the Air Series Don’t List Bluetooth

    GT, GT Max, and the four Air models are display glasses that connect over a wired USB-C cable carrying video, the same kind of connection a monitor uses with a laptop. That cable also supplies power. A product page that mentions only USB-C in its connectivity section, with no Bluetooth version listed, is a wired device.

    Audio differs by model:

    Model Speakers Microphone
    GT / GT Max Built-in quad-speaker system, tuned with Bang & Olufsen Not listed on either product page
    Air 4 Pro Four speakers, per the product page Not listed here
    Air 2s / Air 3s / Air 3s Pro Check each product page Check each product page

    GT and GT Max receive power, video, and audio through their USB-C connection, as RayNeo’s GT series support guide explains; their speakers do not need a separate Bluetooth pairing. A microphone isn’t listed, so don’t assume the glasses provide voice input for calls.

    For wireless audio with glasses that don’t list Bluetooth, the Bluetooth connection runs between your phone and your earbuds directly, and the glasses handle the video signal over the cable.

    Choosing Based on How You Want to Connect

    For wireless AI glasses with on-screen captions, iO pairs with a phone over Bluetooth 5.4 and is listed as MFi Certified. Setup and connected app features use the RayNeo app; online features need the paired phone’s network connection. iO has no speaker, so its captions and notifications are visual rather than spoken.

    For a camera built into the frame alongside a wireless connection, X3 Pro is RayNeo’s only current model with a camera. Its product page centers on temple touch controls, voice interaction, and Apple Watch control on compatible Apple Watch models, paired to a phone through the RayNeo App.

    For a cinema-style viewing or gaming display, GT Max and the lighter GT use USB-C video rather than Bluetooth pairing. The connected phone, tablet, or laptop needs DisplayPort Alt Mode output; a console needs a compatible powered HDMI adapter setup. Both glasses include B&O-tuned speakers.

    Frequently Asked Questions

    Does a higher Bluetooth version always mean better audio quality on RayNeo glasses?

    Not by itself. The version determines what a chipset can support, but the codec used depends on the implementation and the connected phone, details RayNeo hasn’t published per model.

    Why don’t GT, GT Max, and the Air series list Bluetooth?

    They connect over a wired USB-C video cable rather than a wireless link to a phone. GT and GT Max have built-in speakers, and Air 4 Pro’s product page lists four speakers. Not having Bluetooth doesn’t mean a model has no speakers; check each model’s page.

    Can I still use wireless earbuds with RayNeo Air or GT glasses?

    Yes. The Bluetooth connection for audio runs between your phone and your earbuds directly, so pairing earbuds to your phone works independently of how the glasses connect.

    Does iO’s MFi certification matter if X3 Pro doesn’t have it?

    MFi is Apple’s accessory program, so it’s relevant to iPhone users. RayNeo hasn’t published what the certification changes for iO in day-to-day use, so it’s not a reason on its own to assume better call or reconnection behavior. Pairing for both models works through the RayNeo App.

    Will a Bluetooth 5.3 device like X3 Pro still work with an older phone?

    Bluetooth is generally backward compatible, so a newer radio can pair with a phone running an older Bluetooth version, though newer features need support on both sides. The more relevant check for X3 Pro is the RayNeo App’s minimum OS requirement.

    Does the Bluetooth version affect how far I can walk from my phone?

    Range depends mostly on the radio class and on obstacles such as walls, not on the version number alone. RayNeo hasn’t published a range figure for either model.

    Bottom Line

    RayNeo’s lineup splits into two groups. X3 Pro and iO pair wirelessly over Bluetooth (5.3 and 5.4 respectively). GT, GT Max, and the Air series connect by wired USB-C. GT and GT Max have built-in B&O speakers, and Air 4 Pro lists four speakers. Which group fits depends less on the Bluetooth version and more on whether you want a wireless pair that works alongside your phone or a wired display for video.
