In short
Keep your Px7 S2 or buy one used; Px7 S3, the current model, adds aptX Lossless, Bluetooth 5.3 and eight microphones. The 2022 S2 has 40mm bio-cellulose drivers, aptX Adaptive, six microphones and a 30-hour battery, and weighs 307 grams. On paper it matches the 2023 Px7 S2e, which mostly added a retune and new colors. Bowers & Wilkins has archived it, so skip it if you want to buy new.
Who it is for
- Secondhand shoppers on a budget. A used Px7 S2 has the drivers, battery rating and weight that the 2023 Px7 S2e kept.
- Owners of the 2019 PX7 ready for a newer pair. Px7 S2 moved to Bluetooth 5.2 and gets about 7 hours from a 15-minute charge, two more than the original.
- Current owners whose pair still works. The next real step is Px7 S3, and only if you'd use aptX Lossless or its eight microphones.
Who should skip it
- Listeners whose phones can stream aptX Lossless. It arrived with Px7 S3, the current Px7, along with Bluetooth 5.3, eight microphones and a 300-gram build.
- Buyers who want a new pair in the box. Bowers & Wilkins has moved Px7 S2 to its archive, so you'll be shopping secondhand.
What sets it apart
- 40mm bio-cellulose drivers, the same driver Bowers & Wilkins lists for Px7 S2e.
- Faster top-ups than the 2019 PX7: about 7 hours from a 15-minute charge, against 5.
- Two devices connected at once over Bluetooth 5.2, with aptX Adaptive at the top of its codec list.
Caveats
- A used pair's battery has aged, so don't count on the full 30 hours Bowers & Wilkins rated when it was new.
- There's no IP rating to lean on if you get caught in the rain or wear it for a workout.

Px7 S2 next to S2e and S3
Bowers & Wilkins put Px7 S2 on sale on 29 June 2022, three years after the original PX7, which had 43.6mm drivers, Bluetooth 5.0 and a 310-gram weight. The S2e followed in September 2023, and Px7 S3 is now the current Px7, while the S2 itself has moved to Bowers & Wilkins’ archive.
| Spec | Px7 S2 | Px7 S2e | Px7 S3 |
|---|---|---|---|
| On sale | 29 June 2022 | 19 September 2023 | Current model |
| Bluetooth | 5.2 | 5.2 | 5.3 |
| Best codec | aptX Adaptive | aptX Adaptive | aptX Lossless |
| Microphones | 6 | 6 | 8 |
| Weight | 307 g | 307 g | 300 g |
Apart from the dates, the first two columns match, which is what makes a used S2 worth a look. Px7 S3 is the real step up, with aptX Lossless (from a phone that can send it), Bluetooth 5.3 and eight microphones.
Battery and charging
| Mode | Px7 S2 |
|---|---|
| Streaming, noise cancelling on | Up to 30 hours |
| 15-minute charge | About 7 hours |
| Full charge | About 2 hours |
Codecs, pairing and noise cancelling
On Bluetooth 5.2, Px7 S2 handles aptX Adaptive, aptX HD and aptX Classic, and falls back to AAC or SBC for phones without aptX. It can stay connected to two devices at once, which suits a phone and a laptop, and it remembers up to eight.
Hybrid noise cancelling and Ambient Pass-Through are both there, and a wear-detection sensor knows when the headphones come off.
Buying a used Px7 S2
It launched at $399 in the US, £379 in the UK and €429 in Europe, in Black, Blue and Gray. Bowers & Wilkins has archived it, so the secondhand market sets the price; compare any offer with a discounted Px7 S2e before you buy.

Frequently asked questions
Is Px7 S2 the same as Px7 S2e?
Mostly. Both list 40mm bio-cellulose drivers, 30 hours, six microphones, aptX Adaptive on Bluetooth 5.2 and 307 grams. S2e, from 19 September 2023, is Bowers & Wilkins' retune of the S2, and it added colors such as Forest Green and Ruby Red.
What should come with a used Px7 S2?
The carry case and two 1.2m cables, one USB-C to USB-C and one USB-C to 3.5mm. The case matters more than it would with a fold-up Sony 1000X: Px7 S2 isn't described as folding, so its 189 × 63 × 233 mm case is how it travels.
Which app does Px7 S2 use?
Bowers & Wilkins Music, on iOS and Android. It's where you set the EQ, noise cancelling, Ambient Pass-Through and the wear sensor, and where firmware updates come from.
What impedance does Px7 S2 have?
33 Ω input impedance, by Bowers & Wilkins' figures, with distortion under 0.1% at 1 kHz and 10 mW.
