• SoundPEATS Air5 — biggest strength: Dual-certified hi-res wireless audio (LDAC at 990kbps plus aptX Lossless) with Adaptive Hybrid ANC, up to 37 hours total playtime, and IPX5 water resistance.
• SoundPEATS Air5 — biggest trade-off: It's a Bluetooth earbud, so your music lives on your phone, and it relies on a charging case and app for the full feature set.
• RUIZU 64GB — biggest strength: 64GB of built-in storage expandable to 128GB via microSD, with a CNC aluminum alloy body and wide lossless format support (FLAC, APE, WAV, ALAC, DSD256).
• RUIZU 64GB — biggest trade-off: It's a wired, standalone player with no Bluetooth and no streaming — you manage your own files, and battery life is around 5–7 hours.
• Who each pick is for: SoundPEATS Air5 is for commuters, gym-goers and phone-based listeners who want wireless ANC sound; RUIZU 64GB is for people who want a pocketable offline library and zero notifications.
The SoundPEATS Air5 is built around one idea: getting high-resolution sound through the air without wires. It supports both LDAC (990kbps) and aptX Lossless, and it carries Snapdragon Sound and Hi-Res Audio certification. In practice, that means the earbuds are designed to transmit far more data than standard Bluetooth — the manufacturer states over three times as much — so listeners who care about detail in their streaming service or local files get a path that preserves more of it. The 10mm composite driver with a multi-layer PU+PEEK diaphragm and an N50 dual magnet system is the hardware behind the tuning, aimed at smooth mids, clear highs and controlled bass rather than a boomy one-note low end.
Then there's the quiet part. Adaptive Hybrid Active Noise Cancelling pairs with an isolated rear chamber design that acts as a physical noise barrier, so the feature set is clearly aimed at commuting, open-plan offices and flights. Add Bluetooth 5.4 with LE Audio support, AI wind noise reduction, an IPX5 rating and up to 37 hours of total playtime with a 10-minute quick charge giving roughly 2 hours of playback, and you have a pair designed for all-day, on-the-move use. The PeatsAudio app handles EQ presets and customization.
Buy it if you want wireless earbuds for the gym, commute or calls, and you want your music to come from your phone with strong noise cancelling. Skip it if you want a screen-free device with no phone involved, or if you prefer wired listening with local files and no charging case.
The RUIZU 64GB goes the opposite direction. It's a standalone digital audio player machined from CNC aluminum alloy, measuring 2.36 × 1.81 × 0.55 inches and weighing 1.76 oz. It has 64GB of internal memory, expandable up to 128GB with a microSD card, and it supports a long list of formats including MP3, WMA, OGG, APE, FLAC, WAV, AAC-LC, M4A, ALAC and DSD256. If you have a folder of lossless albums you actually own, this is the kind of device that plays them without asking you to sign into anything.
The interface is a 2-inch HD IPS touchscreen with a Home button, and the playback controls are unusually flexible for a player this small: customizable EQ, four favorites or folder playlists, and shuffle, repeat-one, folder-loop, sequential or all-loop modes. There's a useful detail here — you can skip tracks with the screen off, which matters when you're jogging and don't want to look down. Rounding it out are extras like a stopwatch, calendar, volume limit, sleep timer, 21 languages and power-saving shutdown. Battery is a 380mAh cell rated for roughly 5–7 hours, and it charges and transfers over USB-C. A pair of 3.5mm wired headphones and a protective pouch are included.
Side-by-Side: Which Should You Choose?
• Best for wireless listening → SoundPEATS Air5. Bluetooth 5.4 with LDAC and aptX Lossless; the RUIZU has no Bluetooth at all.
• Best for noise cancelling → SoundPEATS Air5. Adaptive Hybrid ANC plus an isolated rear chamber; the RUIZU is a wired player with no ANC.
• Best for battery life → SoundPEATS Air5. Up to 37 hours total with the case versus roughly 5–7 hours on the RUIZU.
• Best for a phone-free music library → RUIZU 64GB. 64GB internal, expandable to 128GB, with no phone or account needed.
• Best for lossless file hoarders → RUIZU 64GB. It plays FLAC, APE, WAV, ALAC and DSD256 from local storage.
• Best for workouts and running → SoundPEATS Air5 for its IPX5 rating and secure in-ear fit; the RUIZU works too, thanks to screen-off track skipping, but it's a wired setup.
• Best for kids, seniors or gift buyers → RUIZU 64GB. Simple touchscreen navigation, a volume limit, a sleep timer and 21 languages make it easy to hand over.
• Best for commuting and calls → SoundPEATS Air5. AI wind noise reduction and touch controls suit noisy streets and open offices.
If I had to pick one for myself, I'd take the SoundPEATS Air5. My reasoning is simple: for how most people actually listen in 2026 — from a phone, on the move, in noisy places — the Air5 covers more ground. Lossless-grade Bluetooth codecs, adaptive ANC, IPX5 and up to 37 hours of total playtime make it the more versatile everyday tool. In my opinion the RUIZU 64GB is the better buy only for a specific person: someone who wants a self-contained, phone-free player for a local lossless library, or who's shopping for a kid or senior who needs simplicity. If that's you, the RUIZU wins clearly. Otherwise, the Air5 is where I'd put my money — and you should check the current price on Amazon before deciding.
FAQ
No. Its connectivity is Aux and USB only, and there's no active noise cancelling. It's a wired, standalone hi-res player. If wireless audio and ANC matter to you, the SoundPEATS Air5 is the one that has both.
No. It's a Bluetooth earbud, so your music comes from your phone, tablet or computer. The RUIZU 64GB is the opposite: 64GB of built-in storage, expandable to 128GB via microSD, so it holds your files directly and needs no other device.
It depends on how you listen, and prices change, so check the current price on Amazon for both. The Air5 packs more features per use case for phone-based listeners — ANC, lossless codecs, 37 hours. The RUIZU gives you local storage and format flexibility without needing a phone. Neither is universally cheaper; match it to your setup.
