Best Buy

Compatibility is less about a single spec and more about how a gadget connects to what you already own. Some products in this group lean on a phone app, some tether to a phone or computer, and some run their own operating system. Knowing which model a device uses helps you avoid surprises after purchase.

This page compares eight gadgets, from wearables like the Garmin Vivosmart 5 and Oura Ring 4 to the BOOX Note Air5 C e-ink tablet and the XREAL Air 2 Ultra glasses. Scores come from GizmoDrift's DriftScore, and the details below come from the specs and notes we have on file. Check the connection type, app requirements, subscription terms and regional limits for each product against the gear you use every day before you buy.

How to choose

Check how the device connects

Connection type decides what the gadget can pair with. The Ultrahuman Ring uses Bluetooth 5.0 and the Oura Ring 4 uses Bluetooth 5.3, so both depend on a phone app to show your data. The Plaud NotePin S adds Wi-Fi to Bluetooth, and the Withings Body Scan also lists Wi-Fi plus Bluetooth. The Garmin Vivosmart 5 gets GPS through a connected phone rather than built-in hardware. If a device needs your phone nearby, confirm you are comfortable with that daily dependency.

Know which gadgets need a tether

Some products only work when linked to another device. The XREAL Air 2 Ultra requires a tethered connection to a phone or computer, so it will not run on its own, and its AR app ecosystem is limited. The Meta Quest 3S, by contrast, is a standalone headset built on the Snapdragon XR2 Gen 2 chip, though it comes with Meta's account requirements. Decide whether you want a screen extension for gear you already own or a self-contained device with its own store and sign-in.

Weigh subscriptions and cloud dependence

Ongoing costs and cloud services affect long-term compatibility. The Plaud NotePin S needs a paid plan for full AI features ($99.99 per year for Pro) and depends on cloud processing, with a free tier of 300 minutes per month. The Oura Ring 4 lists an optional $5.99 monthly subscription for full features. The Garmin Vivosmart 5 and Ultrahuman Ring are listed as requiring no subscription. If you want to avoid recurring fees, that difference matters as much as the hardware.

Confirm software support and regional limits

Look at the platform each device runs and where its features are cleared for use. The BOOX Note Air5 C runs Android 15 with Google Play Store access, so it can use many apps you may already have. The Withings Body Scan lists ECG clearance that varies by country, so check availability where you live. The Garmin Vivosmart 5 was released in 2022, which is worth remembering if you expect the newest software features to keep arriving.

Frequently asked questions

Which gadgets here work without a phone?

The Meta Quest 3S is a standalone headset, and the BOOX Note Air5 C runs Android 15 on its own. Most wearables, including the Oura Ring 4 and Ultrahuman Ring, rely on a phone app to display your data, and the XREAL Air 2 Ultra needs a tethered phone or computer.

Do any of these avoid subscription fees?

The Garmin Vivosmart 5 is listed as needing no subscription, and the Ultrahuman Ring is listed with all features available without monthly fees. The Oura Ring 4 and Plaud NotePin S both have paid tiers for full features, so check the terms before buying.

Do I need an internet connection for these devices?

It depends on the product. The Plaud NotePin S relies on the cloud for AI processing, and the Withings Body Scan connects over Wi-Fi and Bluetooth. Wearables like the Ultrahuman Ring store up to 16 days of data on the device before syncing to the phone.

Is the XREAL Air 2 Ultra a replacement for a VR headset?

No. It is a lightweight pair of AR glasses with a 52-degree field of view that must stay connected to a phone or computer. If you want full VR immersion or standalone use, the Meta Quest 3S is a better fit for that goal.
