Sony WH-CH720N vs Sennheiser ACCENTUM Plus Wireless

What you'll actually notice

Both are neutral-platform over-ear ANC headphones, but they feel like different ownership propositions once the specifications are translated into daily use.

Sony WH-CH720N is the lighter route at 192g, with 35 hours ANC-on / 50 hours ANC-off, multipoint and passive 3.5mm playback. ACCENTUM Plus is heavier at 227g, lists up to 50 hours battery, adds aptX and aptX Adaptive, and has a 10-minute = up to 5-hour fast charge.

So Sony's clearest advantage is physical lightness. Sennheiser's clearest advantages are codec flexibility and charging recovery. Neither set of facts proves better sound, ANC or comfort.

What changes the choice

Does lower weight matter every day?

Sony is 192g; ACCENTUM Plus is 227g.

What this means: Sony removes 35g from the published wearing/carrying figure. That is a meaningful physical difference, especially for long desk sessions or frequent bag carry.

It still does not prove comfort because clamp, pad shape and head fit are personal.

Switch when: choose Sony if you repeatedly prioritise low mass. Choose Sennheiser if the extra 35g is acceptable in exchange for its source and charging features.

Which battery figure is actually comparable?

Sony explicitly states 35 hours with ANC on and 50 hours with ANC off.

ACCENTUM Plus gives a up to 50 hours battery figure without the same ANC-mode split in the current exact record.

What this means: both clearly support long everyday use, but the numbers are not perfectly mode-matched. It would be misleading to call Sennheiser the battery winner on those fields alone.

Switch when: treat battery as broadly strong on both. Let weight, codec support and charging recovery do more of the deciding unless your own mode-specific evidence expands later.

Does fast charging solve a real problem?

ACCENTUM Plus is rated at 10 minutes for up to 5 hours.

Sony's current exact record gives a 3.5-hour full charge but does not establish an equivalent quick-charge claim.

What this means: Sennheiser has the clearer emergency-recovery story for buyers who often discover a low battery just before leaving.

Switch when: choose ACCENTUM Plus if opportunistic charging is part of your routine. If you charge predictably overnight, fast-charge advantage should remain secondary.

Do the codec differences match your sources?

Sony supports SBC and AAC. ACCENTUM Plus adds aptX and aptX Adaptive to SBC/AAC.

What this means: Sennheiser gives compatible source devices more codec options. That is a compatibility advantage, not evidence that it automatically sounds better.

Switch when: choose ACCENTUM Plus if aptX-family support is a specific source requirement. If you mostly use AAC/SBC devices, do not pay extra attention to codecs you will never use.

Does wired playback separate the pair?

Sony supports a detachable 3.5mm cable with passive operation. ACCENTUM Plus includes an auxiliary cable.

What this means: both have a conventional wired fallback, so wired access itself is not a strong separator.

Switch when: do not choose either simply because it has a cable. Focus instead on whether Sony's low weight or Sennheiser's charging/codec package changes your daily use.

One point that matters less than it first appears is multipoint: both products already qualify for multi-device use, so phone-plus-laptop switching does not create a clean winner here. Likewise, both provide a conventional wired fallback. Once those shared capabilities are removed from the decision, the comparison becomes much more disciplined: Sony asks whether 192g is worth prioritising; Sennheiser asks whether aptX-family compatibility and strong fast charging solve recurring problems. That is a more useful distinction than counting the total number of features.

The practical choice

Choose Sony WH-CH720N when you want a very light over-ear ANC headphone, 35-hour ANC endurance is already enough, and your sources do not need aptX-family codecs.

Choose Sennheiser ACCENTUM Plus Wireless when the extra source flexibility and 10-minute = up to 5-hour recovery are more valuable than Sony's lower weight.

If those differences are irrelevant, this becomes a close mainstream ANC comparison where current price and owner feedback should carry more weight than unsupported performance claims.

When to choose Sony WH-CH720N

• Low 192g weight matters for long wear or travel.
• 35-hour ANC-on battery is already ample.
• SBC/AAC support matches your devices.
• Passive 3.5mm fallback is enough.

When to choose Sennheiser ACCENTUM Plus Wireless

• aptX or aptX Adaptive support matters to your sources.
• Quick top-ups are important.
• You accept the higher 227g weight.
• You want Sennheiser's music-first midrange role.

Choose neither when

Choose neither if the real requirement is true wireless pocketability, sport-secure fit or physically open awareness. Both remain full-size sealed ANC headphones.

PIQSY conclusion

Choose Sony when low 192g weight and straightforward everyday ANC matter most; choose ACCENTUM Plus when broader codec support and much stronger fast-charge recovery are more useful.

The decision should turn on weight, source compatibility and charging behaviour—not an invented sound or ANC ranking.
