If you want a lightweight true-wireless set with adaptive noise cancellation and Qualcomm aptX for everyday streaming, choose Bowers & Wilkins Pi5; if you need planar magnetic drivers, the full Snapdragon Sound codec suite with aptX Adaptive and aptX Lossless, and wide-band calling, choose Edifier STAX Spirit S10.

Bowers & Wilkins Pi5 vs Edifier STAX Spirit S10 at a Glance

• Bowers & Wilkins Pi5 — biggest strength: A tidy, familiar true-wireless design with Bluetooth 5.0 and Qualcomm aptX, three levels of adaptive noise cancellation, four mics, and a charging case that pushes total playback to about 12 hours.

• Bowers & Wilkins Pi5 — biggest trade-off: It's a standard dynamic-driver in-ear with an older Bluetooth generation and no LDAC or aptX Lossless, so it won't satisfy someone chasing the highest-resolution wireless codecs.

• Edifier STAX Spirit S10 — biggest strength: A modularized planar magnetic driver with an ultra-thin diaphragm, plus the full Qualcomm Snapdragon Sound suite (aptX, aptX Adaptive, aptX Lossless) alongside LDAC and LHDC 5.0, six mics, and 32kHz aptX Voice calling.

• Edifier STAX Spirit S10 — biggest trade-off: Earbud battery life is listed at around 6 hours, it relies on the EDIFIER ConneX app for customization and controls, and the planar driver design is a more specialist proposition.

• Who the Pi5 is for: Buyers who want a simple, low-fuss in-ear with adaptive ANC and aptX for daily streaming and calls.

• Who the S10 is for: Listeners who care about codec quality, planar magnetic detail, and the best possible wireless calling.

Bowers & Wilkins Pi5: Who It's For

The Pi5 is the more conventional of the two. It's a true-wireless in-ear built around a dynamic driver with a frequency range of 10Hz to 20kHz, connected over Bluetooth 5.0 with Qualcomm aptX. That combination is aimed squarely at people who stream from a phone, tablet, or PC and want a stable, familiar connection rather than a spec sheet full of exotic codecs. It can hold two devices at once via multipoint, which is genuinely useful if you're flipping between a laptop and a phone during the day.

The noise cancellation is the headline feature for commuters. A multi-function button on the left earbud cycles between three adaptive ANC levels — high, low, and auto — so you can dial in how much of the outside world you let in. Four built-in mics handle call clarity, and the controls support both touch and voice, which matters if you like barking commands at a voice assistant while your hands are busy. Everything ships in a sturdy charging case with two 350mAh batteries, and a 15-minute quick charge gets you roughly two hours of playback. Total playback including the case is about 12 hours.

There's one practical note worth repeating: Bowers & Wilkins explicitly warns that if the earbud tips don't match your ear canals, or the buds aren't seated properly, sound quality and call performance suffer. So budget a little time to swap between the included S, M, and L tips. If you want a no-drama in-ear with adaptive ANC for streaming and calls, this is a sensible pick. If you're chasing the most advanced wireless codecs available, or you want a metallic build with a wear sensor, look elsewhere.

Edifier STAX Spirit S10: Who It's For

The S10 is the enthusiast's option, and it's not shy about it. Edifier calls it the first wireless planar magnetic noise-canceling earbud, and the driver design backs that up: a modularized planar magnetic driver with a 12mm diaphragm, an ultra-thin 10μm planar diaphragm on a 2μm polymer substrate, and second-generation EqualMass wiring that balances magnetic field variation to cut distortion. In plain terms, planar drivers are prized for fast transient response and fine detail, and this is a set built around that philosophy.

The codec story is where it separates itself from the Pi5. The S10 supports the full Qualcomm Snapdragon Sound suite — aptX, aptX Adaptive, and aptX Lossless — plus LDAC and LHDC 5.0. For anyone streaming high-resolution audio, that's a much wider net of codecs than the Pi5's aptX-only approach. It also runs Bluetooth 5.4, a generation ahead of the Pi5, and the frequency response extends to 40kHz. That's the kind of headroom that matters if you're feeding it hi-res sources.

Calling is a genuine strength too. Each earbud packs three high-sensitivity mics — six total — with Qualcomm aptX Voice and a 32kHz calling bandwidth, which should translate to clearer vocals on calls. You also get 3rd-generation adaptive hybrid ANC, a wear sensor that auto-pauses and resumes, multipoint for two devices, IP54 water resistance, and seven pairs of ear tips for fit. Customization runs through the EDIFIER ConneX app. The trade-off is battery: the earbuds are rated at around 6 hours, and the controls lean on the app. If you want maximum codec flexibility and planar detail, this is your pick. If you want the longest stated playback and the simplest possible experience, think twice.

Side-by-Side: Which Should You Choose?

• Best for codec flexibility → Edifier STAX Spirit S10. aptX, aptX Adaptive, aptX Lossless, LDAC, and LHDC 5.0 cover far more streaming scenarios than the Pi5's aptX alone.

• Best for battery life → Bowers & Wilkins Pi5. Roughly 12 hours total with the case versus the S10's 6-hour earbud figure.

• Best for call clarity → Edifier STAX Spirit S10. Six mics and 32kHz aptX Voice wide-band calling edge out the Pi5's four-mic setup.

• Best for a simple, no-app experience → Bowers & Wilkins Pi5. On-earbud ANC cycling and touch/voice controls without needing software.

• Best for high-res streaming → Edifier STAX Spirit S10. LDAC, LHDC 5.0, and the Snapdragon Sound suite make it the more capable partner for hi-res sources.

• Best for everyday commuting → Bowers & Wilkins Pi5. Three adaptive ANC levels and a quick-charge case keep it practical.

• Best for fit tuning → Edifier STAX Spirit S10. Seven pairs of ear tips versus the Pi5's three sizes.

• Best for build and durability features → Edifier STAX Spirit S10. IP54 rating, metal-and-plastic enclosure, and a wear sensor the Pi5 doesn't list.

My Verdict

In my opinion, if streaming quality and codec support are what you're optimizing for, I'd buy the Edifier STAX Spirit S10. The planar magnetic driver, the full aptX Adaptive and Lossless suite, LDAC, LHDC 5.0, and six mics make it the more future-proof set for high-resolution streaming and calls. I'd only steer you to the Bowers & Wilkins Pi5 if battery life and simplicity matter more than codec depth — its 12-hour total playback and app-free controls are genuinely easier to live with day to day. Match the pick to your priority, and check the current price on Amazon before you commit.

FAQ

What is aptX Adaptive headphones?

aptX Adaptive is a Qualcomm audio codec that adjusts its bitrate and latency to suit what you're doing — favoring stability for video and higher quality for music. The Edifier STAX Spirit S10 explicitly supports aptX Adaptive as part of the Snapdragon Sound suite, while the Bowers & Wilkins Pi5 lists Qualcomm aptX without specifying the Adaptive variant.

What are the best earphones for streaming between these two?

For codec-rich streaming, the Edifier STAX Spirit S10 is the stronger pick because it supports aptX, aptX Adaptive, aptX Lossless, LDAC, and LHDC 5.0. The Bowers & Wilkins Pi5 relies on aptX over Bluetooth 5.0, which is capable but less flexible across hi-res sources.

Can these work as a voice assistant Bluetooth headset for streaming?

The Bowers & Wilkins Pi5 explicitly lists voice control alongside touch controls, so assistant commands are built in. The Edifier STAX Spirit S10 supports app and touch control, and while it doesn't call out voice assistants in its spec sheet, its six-mic array is designed for clear calls.

Are these deep bass open ear headphones for streaming?

No — both are in-ear true-wireless earbuds, not open-ear designs. The Bowers & Wilkins Pi5 uses a dynamic driver with a 10Hz–20kHz range, and the Edifier STAX Spirit S10 uses a planar magnetic driver with a 20Hz–20,000Hz range and extension to 40kHz.
