Px8 S2 is a premium materials and sound choice for listeners willing to accept weaker ANC value and software tradeoffs. Try the headband range and pads, and confirm codec support on your phone before paying for aptX features. The observed Warm Stone page offers a stock notification, so its displayed sale price is not proof of immediate availability.

What changed
From Px8 to Bowers & Wilkins Px8 S2.
The immediate predecessor is Px8. Both answer the same premium wireless noise-cancelling headphones buying decision; that continuity of role is not proof that their hardware or software is identical. The accepted current-model sources document the features below but do not establish a complete generation-to-generation baseline. Exact deltas are marked unverified where the evidence does not settle them.
| Area | Predecessor | Current model | Net change | Buyer impact |
|---|---|---|---|---|
| Core role carried over | Px8 serves the premium wireless noise-cancelling headphones role. | The current model continues that role. | The buying job is carried over; exact implementation equivalence is unverified. | An existing working unit remains a meaningful baseline; a new generation alone does not establish an upgrade benefit. |
| Materials and runtime | Px8: exact specification baseline not reverified in this source set. | Px8 S2 lists leather/aluminum construction, 310 g weight and 30-hour battery. | Exact changes in weight, construction and runtime versus Px8 were not verified; lighter weight or longer life is not claimed. | An existing Px8 owner should seek a specific comfort or service need before replacing a working pair. |
| Audio and app | Px8: exact specification baseline not reverified in this source set. | S2 lists USB-C audio, aptX Lossless/Adaptive, multipoint and five-band EQ. | Which capabilities are additions versus Px8, and their net audible effect, are unverified in this source set. | Check your phone’s codec support and your existing app features before treating these as upgrade benefits. |
Independent evidence
What reviewers and owners actually found.
What Hi-Fi praised Px8 S2’s sound and build while finding weaker ANC and app, connectivity and control quirks. SoundGuys used a company-provided unit for one week, highlighting premium construction and travel use alongside no ingress rating and possible high-frequency sensitivity. That is not long-term durability evidence. An exact-model Reddit owner liked the connectivity and leather pads but found the headband extension marginal and stock bass excessive. Fit and EQ preferences are personal, so try the adjustment range before buying.
