Braun Series 7 vs Series 9
The two shavers are closer than the price gap suggests, and the difference is mostly in what Braun is willing to tell you about each one.

The short version
Buy the Series 7 unless your beard is dense or your skin complains. Both publish the same five-minute quick charge and the same full waterproofing; the Series 9 publishes 60 minutes of runtime against 50. The real gap is two figures the Series 7 does not publish at all: a cutting element count (the Series 9 states five, each named) and an 18-month head replacement interval.

Four rows are identical. One differs by ten minutes. Two are blank on one side, and those two rows are what you are actually buying.
The element count is the real difference
Braun publishes five cutting elements on the Series 9 - two gliding foils, a SkinGuard, a Direct & Cut blade and a Lift & Cut blade - plus a titanium-coated ProLift blade. Each one is named and has a stated job.
For the Series 7 Braun publishes no element count at all. Not a lower number: no number.
The honest caveat: an absent figure is not a known-lower figure. The Series 7 may well have four elements. Braun simply does not say, which means it cannot be placed on the same scale - and on a site that ranks on published specifications, that is where it loses.
The other blank: running cost
Braun publishes an 18-month foil-and-cutter replacement interval for the Series 9. It is the only replacement figure published by any foil shaver in this ledger.
It publishes none for the Series 7. Both use proprietary cassettes, so replacement heads are priced by Braun either way - the difference is that on one of them you can work out what the next three years cost and on the other you cannot.
That is a genuine argument for the flagship that has nothing to do with the shave. This page covers what to watch for when no interval is published.
What is genuinely identical
- The five-minute quick charge. The most practically useful charging specification in this ledger, and both have it. This is the feature you actually use.
- Full waterproofing. Both publish 100 per cent, so both work wet with lather - which changes the technique.
- The 360-degree flexing head and AutoSense. Published on both.
- The missing full charge time. Braun publishes it on neither, which is a gap Panasonic fills with a stated 60 minutes.
Which to buy
| If... | Buy | Because |
|---|---|---|
| Your skin gets irritated | Series 9 | Five published elements, fewer passes |
| Your beard is dense or coarse | Series 9 | Same reason, felt on the neck |
| You want the running cost knowable | Series 9 | 18-month interval, published |
| Your beard is average | Series 7 | Same charge, same waterproofing, less money |
| You shave a few times a week | Series 7 | Less cumulative irritation to solve for |
| You are not sure electric suits you | Neither yet | Find out cheaply first |
That last row is worth taking seriously. The Remington F5 publishes two cutting elements and the same 60 minutes of runtime as Braun's flagship - which is the clearest illustration on this page that runtime is not what the money buys. The budget roundup is the honest place to start if you have never owned a foil shaver.
The verdict
Series 7 for most people. It publishes the same quick charge, the same waterproofing and the same head technology, and gives up ten minutes of runtime plus two figures many buyers will never need quantified.
Series 9 if you are buying comfort or predictability. Five named cutting elements and an 18-month interval are real, checkable reasons to spend up - and they are the only two this category offers.

Our pickThe closest electric shave
Braun Series 9 PRO+
Five synchronized shaving elements — two gliding foils, a SkinGuard, a Direct & Cut blade and a Lift & Cut blade — plus a titanium-coated ProLift blade, 60 minutes of runtime, a five-minute charge for one shave, and it is fully waterproof. If the requirement is 'as close as an electric gets', this is the answer and there is not much argument about it.

What it gets right
- Five published cutting elements, each with a stated job, plus the ProLift blade
- 60-minute Li-Ion runtime, the longest of the shavers here
- 5-minute quick charge for a full shave
- 100% waterproof; usable wet with lather
Flaws
- Replacement head cassettes are proprietary and are the real long-run cost
- Braun's published 18-month replacement interval is guidance on its parts pages rather than a figure on the product specification, so it is easy to miss before you buy
- The most expensive way to remove hair in this ledger
The working behind the 7.4
- How long it lasts: not scored
- Not scored. This is a durable item, not a consumable, so how long it lasts is an assumption about service life rather than something the pack size tells us.
- Ease of switching: 9.0
- Wet-and-dry with 60 minutes of runtime and a 5-minute quick charge; nothing about daily use requires a decision (++). Braun publishes an 18-month foil-and-cutter replacement interval, which at least makes the running cost plannable (+), but the cassettes are proprietary so the price of it is Braun's to set (-).
- Refill economics: 4.0
- Only this maker's refill fits, so the ongoing price is set by the maker rather than by a market. This is where the real cost of ownership hides.
- What the maker publishes: 8.0
- 4 of 5 specifications a buyer would expect are published: runtimeMin, cuttingElements, waterproof, headReplacementMonths. Not published: chargeMin. 4 / 5 x 10 = 8.0.

2Most of the Series 9 for less
Braun Series 7 (360° Flex)
A 360-degree flexing head, AutoSense power adjustment that reads beard density, 50 minutes of runtime, a five-minute charge for one shave, and full waterproofing. It gives up cutting elements to the Series 9 and very little else, which makes it the sensible stopping point for most faces.

What it gets right
- 360-degree head adaptation, published by Braun
- AutoSense adjusts power to beard density rather than running flat out
- 50-minute runtime with a 5-minute quick charge
- 100% waterproof, wet and dry
Flaws
- Fewer cutting elements than the Series 9, which a very dense beard will feel on the neck
- Same proprietary-cassette running cost as the Series 9
The working behind the 6.3
- How long it lasts: not scored
- Not scored. This is a durable item, not a consumable, so how long it lasts is an assumption about service life rather than something the pack size tells us.
- Ease of switching: 9.0
- 50 minutes of runtime, a 5-minute quick charge, waterproof, and a head that adapts without input (++). Braun does not publish a cutting-element count for this line, so it cannot be compared numerically to the Series 9 (-).
- Refill economics: 4.0
- Only this maker's refill fits, so the ongoing price is set by the maker rather than by a market. This is where the real cost of ownership hides.
- What the maker publishes: 4.0
- 2 of 5 specifications a buyer would expect are published: runtimeMin, waterproof. Not published: chargeMin, cuttingElements, headReplacementMonths. 2 / 5 x 10 = 4.0.

3Speed on a dense beard
Panasonic Arc5 ES-LV67
A 14,000 CPM linear motor producing up to 70,000 cross-cuts a minute across five blades, a head that flexes in 16 directions, and a beard sensor taking 220 readings a second. It is the fastest shaver here on dense growth. The trade is 45 minutes of runtime, the shortest of the three.

- Five blades and a 16-direction flexing head
- Beard sensor with a published 220 detections per second and 14 power adjustments per second
- 3-minute quick charge for one shave; wet and dry
Flaws
- 45 minutes of runtime, the shortest of the shavers here
- Proprietary foil and cutter assemblies
- Louder than the Braun units, which is a real daily consideration
The working behind the 7.2
- How long it lasts: not scored
- Not scored. This is a durable item, not a consumable, so how long it lasts is an assumption about service life rather than something the pack size tells us.
- Ease of switching: 8.5
- The most completely specified shaver here — motor speed, cross-cut rate, sensor rate and head articulation are all published figures (++). 45-minute runtime is the shortest of the three (-).

4The cheapest foil that is not a false economy
Remington F5 Power Series
Skip this one. On this page as the floor rather than as a pick. It publishes two cutting elements against the Series 9's five and the same 60 minutes of runtime as the flagship - which is the cleanest illustration of the argument here. If you are deciding between two Braun tiers, the useful context is that the budget end matches both of them on the figure people compare first and loses badly on the one that actually matters.
Two flexing foils, an interceptor trimmer between them, a pop-up detail trimmer and 60 minutes of cordless runtime from a two-hour charge. It is a fraction of the Braun's outlay and it does not pretend to match it — but for an occasional or travel shaver it is enough tool.

What it gets right
- Published 60 minutes of cordless runtime
- Twin flexing foils with an intercepting trimmer for longer hairs
- Pop-up detail trimmer included
- Costs a fraction of the premium foils here
Flaws
- Two-hour charge time, the slowest here
- Not designed for wet use with lather in the way the Braun and Panasonic units are
- Replacement foils and cutters are proprietary and worth checking the price of before you buy
The working behind the 6.2
- How long it lasts: not scored
- Not scored. This is a durable item, not a consumable, so how long it lasts is an assumption about service life rather than something the pack size tells us.
- Ease of switching: 7.5
- 60 minutes of published runtime (+), pop-up trimmer (+), but a 2-hour charge and no published waterproof rating make it a worse daily tool than anything above it (--).
- Refill economics: 4.0
- Only this maker's refill fits, so the ongoing price is set by the maker rather than by a market. This is where the real cost of ownership hides.
- What the maker publishes: 6.0
- 3 of 5 specifications a buyer would expect are published: runtimeMin, chargeMin, cuttingElements. Not published: waterproof, headReplacementMonths. 3 / 5 x 10 = 6.0.

Questions people actually ask
Is the Series 9 worth the extra?
If your skin gets irritated or your beard is dense, yes - five published cutting elements means fewer passes, and passes are what irritate. If neither applies, you are paying for two published figures rather than a shave you will notice.
What is the actual runtime difference?
Ten published minutes - 60 against 50. That is roughly the difference between three weeks and two and a half weeks of daily shaving, which is not a decision-grade gap for most people.
Do they use the same replacement heads?
No - Braun's cassettes are model-specific, and that is worth checking before you buy either. Braun publishes an 18-month interval for the Series 9 and no interval at all for the Series 7, so the running cost is knowable on one and not the other.
Does the Series 7 have AutoSense too?
Yes - Braun publishes AutoSense power adjustment on both, along with a 360-degree flexing head. On the published feature list the two shavers are remarkably close.
Which for sensitive skin?
The Series 9, on the element count. It is the one specification with a direct mechanism behind comfort - the sensitive-skin roundup weights it the same way.
