Head-to-head

Bowers & Wilkins Px7 S2e vs Px7 S3: Both drop phone Bluetooth during USB listening

The short answer

Choose Px7 S3 for five-band EQ or a verified aptX Lossless source. Px7 S2e remains a sensible choice if bass/treble adjustment and its existing connections cover your needs. For travel, both still need battery power with the analog cable. For work, USB audio disconnects Bluetooth on both, so plan how phone calls will reach you.

Before you choose

The reasoning and the trade-offs

A cable will not rescue an empty battery on a flight

Both require charged, switched-on headphones for analog listening. Pack and charge accordingly. During analog playback, adjust volume and playback on the source rather than expecting the headphone controls to work.

What this is based on

Both English manuals document powered analog operation and source-side playback controls. An airline seat adapter still depends on the aircraft connector.

Main trade-off

Bowers & Wilkins Px7 S2e

The frame is heavier than Px7 S3 by 7 g.

About this comparison

Compare Px7 S2e and Px7 S3 by weight, codec source requirements and wired options. The newer model keeps the same 30-hour advertised playback claim.

Winner by situation

Start with what you need it to do

  • I need airplane audio after the battery dies

    The supplied analog connection requires the headphones to remain charged and powered on.

    Not suitable
    Bowers & Wilkins Px7 S3
    Not suitable

  • I want USB laptop music and a Bluetooth phone call available

    USB mode disconnects Bluetooth. Use the documented wireless multipoint setup if wireless laptop audio is acceptable.

  • I want finer tone adjustment on my current phone

    S3 offers five-band EQ. S2e offers bass and treble controls. This is useful independently of aptX Lossless compatibility.

  • I mostly listen through USB

    Both already support USB audio. The new codec does not affect that wired path.

  • I have a verified aptX Lossless transmitter

    S3 can use the additional codec when source and connection requirements are met.

  • I want longer advertised battery life

    Both claim 30 hours, so the newer model does not solve that request on paper.

What matters in practice

The differences that matter

A cable will not rescue an empty battery on a flight

Both require charged, switched-on headphones for analog listening. Pack and charge accordingly. During analog playback, adjust volume and playback on the source rather than expecting the headphone controls to work.

How we reached this conclusion

Both English manuals document powered analog operation and source-side playback controls. An airline seat adapter still depends on the aircraft connector.

USB music and Bluetooth phone access do not combine here

Connecting USB audio disconnects Bluetooth on both. If you want laptop listening interrupted by phone calls, their documented two-device Bluetooth mode is the relevant setup.

How we reached this conclusion

The manuals distinguish USB audio from Bluetooth multipoint. Multipoint receives one audio stream at a time and allows a call from the second connected device to interrupt the first.

The weight saving is 2.3%

S3 removes 7 g from the published S2e weight.

How we reached this conclusion

(307 − 300) ÷ 307 × 100 = 2.3%.

Two battery claims are unchanged

Both list 30 hours of playback and seven hours from a 15-minute charge.

How we reached this conclusion

30 − 30 = 0 hours. 7 − 7 = 0 quick-charge playback hours.

The new codec adds no benefit to a USB-only routine

Both provide USB audio. aptX Lossless concerns the wireless path rather than that cable.

How we reached this conclusion

The codec requirement applies to Bluetooth transmission. Both manufacturers’ product records list a USB audio interface.

Check your own setup

Which headphones work with the way you listen?

Start with the way you listen. USB charging is not the same as USB audio, and some headphones need power even with a cable. These choices are examples until you apply yours.

Bowers & Wilkins Px7 S2e

Meets these checks

Bluetooth listening.

Bowers & Wilkins Px7 S3

Meets these checks

Bluetooth listening.

Battery figures are manufacturer claims for the stated mode, not measured travel time. Volume, codec, calls and battery age change runtime. Closed earcups can still leak sound. Weight alone does not predict comfort. USB audio needs a compatible source and cable. This check does not assess sound quality, microphone quality or amplifier power.

Choice A
Bowers & Wilkins Px7 S2e

Bowers & Wilkins, Px7 S2e

Px7 S2e

A straightforward alternative to Px7 S3 when USB audio, an analog-source cable and a carry case cover your needs. The newer S3 is 7 g lighter, not a step up in advertised playback hours.

Best matched use
Bass and treble controls are enough for your listening.

Checked facts

  • Weight: 307 g
  • Advertised playback: 30 hours
  • Quick-charge claim: 7 hours from 15 minutes
  • Digital USB audio: Supported

Choice B
Bowers & Wilkins Px7 S3

Bowers & Wilkins, Px7 S3

Px7 S3

Choose Px7 S3 for its 300 g build and updated connection support. It shares the 30-hour playback claim and included USB and analog-source cables of Px8 S2, so those alone do not justify paying more.

Best matched use
You want finer five-band EQ without replacing your phone.

What you give up

Every choice has a cost

If you choose Bowers & Wilkins Px7 S2e

  • aptX Adaptive still needs support from the phone or transmitter.

If you choose Bowers & Wilkins Px7 S3

  • The earcups turn flat but the headband does not fold inward.

What matters in practice

How to make the call

01

A compatible source is the first upgrade check

aptX Lossless is not a universal property of every smartphone. Check the actual transmitter and operating mode before paying for it. A buyer who mainly uses USB audio does not need the new wireless codec to satisfy that routine.

02

Do not oversell seven grams

S3 is lighter, but a 7 g change is small beside differences in pad feel and clamp. Try the new frame if comfort is the reason to upgrade. The weight figure alone is not enough to establish a winner.

03

An older offer can still be the sensible one

S2e already includes the two useful cable paths, a case and the same advertised playback duration. Choose S3 for a specific updated capability or a preferred fit, not because an unchanged 30-hour claim has been repackaged as a benefit.

Check these before buying

  • Choose between USB audio and Bluetooth multipoint before buying for a laptop-and-phone routine.
  • Neither reviewed manual establishes USB microphone support. Confirm that separately if wired calls are essential.
  • Verify aptX Lossless support on the exact source, not merely the presence of Bluetooth.
  • Check seller, condition and cable contents on older S2e offers.

What this comparison cannot tell you

  • Both English manuals attribute up to 30 hours of wireless playback to ANC enabled at average volume. These are manufacturer claims, not a matched real-world endurance test.
  • No audible sound-quality gain is inferred from the codec or product generation.
