Review: Philips Fidelio B5

Introduction and features

The Fidelio B5 is like the Optimus Prime of soundbars. Actually, scratch that. It’s way better than the stuffy old Autobot. The Fidelio B5 is like jazz. It’s cooler, still has that Transformer vibe, and packs a whole lot more funk in its trunk.

You see, Philips’ curvaceous soundbar has a seriously powerful USP: it can switch from traditional soundbar to 4.1 surround sound system in seconds.

At first glance it might look like an ordinary soundbar, with a wireless subwoofer and front-firing speakers, but yank the end units off either side and they become individual wireless satellite speakers that you can place around your room to give you a more cinematic effect.

The switch from 2.1 system to 4.1 surround takes a single beat, and the B5 automatically switches into its cinema mode without you having to do anything. It’s even rocking some impressively simple room calibration tech, which dynamically adjusts the levels in the surround channels to cope with offset placement around your room.

It’s this ease of use which is the hallmark of the Philips Fidelio B5.

In each of the detachable end-speakers is a single, full-range 3-inch driver, and a lithium-ion battery that’s capable of delivering around 10 hours of charge when running wirelessly.

The base soundbar is left with a further pair of 3-inch drivers to make up the two central channels, as well as a pair of 1-inch soft dome tweeters to take care of the high-end audio details.

The wireless 6.5-inch subwoofer is a down-firing affair to bring depth to the cinema sound. It’s also got a relatively small footprint, enabling it to be stowed discretely out of sight.

Connectivity is straightforward enough, with aptX Bluetooth for music playback, and coaxial, analogue 3.5mm and digital optical inputs as well as a HDMI 1.4 ARC output. It also features a pair of HDMI inputs, enabling you to connect multiple devices.

But the B5’s transforming skills don’t stop at its 2.1 to 4.1 transition. Each of those detachable speakers can become individual Bluetooth speakers in their own right – both have a discrete Bluetooth module inside, enabling them to be used independently of the main bar.

With both speakers placed in separate rooms (because we all hate soundclash, right?) you can then have three different audio sources playing between the discrete satellite speakers and the main soundbar unit.

When you detach the speakers from the centre section a pair of buttons are revealed which enable you to switch from surround to Bluetooth mode quickly and easily. And they’re rocking the now-standard aptX support, so you can get its full CD-quality audio capabilities across the wireless connection.

The speakers aren’t that powerful on their own, however. Each is only rated at 8W, so they won’t be shaking the room by themselves, but they’re still able to deliver a decent audio range.


The audio performance of the Philips Fidelio B5 is impressive, whether it’s being used as a traditional 2.1 soundbar or in its more flexible 4.1 configuration.

The clarity of sound, from the constant rumbling bass of a Michael Bay ‘splode-a-thon to dialogue-heavy dramas to detailed hi-res music, is excellent. That wireless sub does a great job of adding depth to the sound while those soft dome tweeters, mixed with Philips’ Crystal Clear Sound processing, keep the aural experience precise and defined.

But how does its headline-grabbing transformation work in practice? Pretty darned well, if I’m honest.

One of the biggest reasons for not having a surround sound system in place at home is the fact that those satellite speakers always end cluttering up the room and getting in the way.

Wired solutions need a whole lot of planning to avoid a chaotic, tangled mess stretching around the lounge like Cthulu’s own tentacles, and even wireless options can be a pain with their need for regular charging.

Having a setup that can house and charge its wireless satellites in a convenient place, and still allow you to switch almost instantly to a surround sound setup, is more than welcome.

Simple surround

The other reason to opt for soundbars over complicated surround sound arrays is all about simplicity, and the Fidelio B5’s unplug and play system is seriously slick.

All you have to do is pull the satellite speakers from their docks; the B5 automatically switches to surround mode, and you can move the speakers around the room as you see fit.

The surround sound performance itself isn’t earth-shatteringly good, but it is effective – although you’re never going to get the precision of a proper Dolby Atmos kit or a 7.1 array.

Of course, if you’re that desperate for the ultimate in spatial audio then you’ll be prepared to drill out your walls to install the satellites, and carve out holes in the ceiling, to create that 3D aural experience.

The rest of us just want something quick, easy and with a decent approximation of cinema sound, which is what Philips has created with this soundbar.

And, if you’re listening to music rather than marvelling at Jessica Jones, you can switch from ‘Movie’ to ‘Music’ mode with a touch on the elegant remote control. This then alters the signal to deliver the full audio around the room, rather than just the surround channels.

That remote also enables you to adjust bass and treble, as well as nudge the audio synchronisation if the image and sound are falling out of step.


The Philips Fidelio B5 is a seriously smart bit of kit, straddling the line between straight soundbar and home cinema surround, and doing it all with ease and style.

For those who don’t want to mess up the feng shui of their living room with a permanent surround sound system, it’s a great alternative.

The soundbar market is an incredibly crowded one right now, and it’s very refreshing to see Philips doing something different with the Fidelio range.

We liked

The big thing about the B5 is the simplicity with which you can switch between using it as a standard 2.1 system and a broader 4.1 surround sound array.

There’s literally no catch – the connection is a simple dock that manages a secure connection without feeling like it’s jealously holding onto the speakers when you try to remove them.

And simply by plugging them back in you’ll start the speakers’ batteries charging, which is handy if you’ve left them out overnight and they’ve run down.

The Fidelio B5 is also rather good looking as soundbars go. It’s curved design works whether it’s sat on your media centre or attached to the wall, and the otherwise-hidden LED display only appears when something’s being adjusted, keeping things relatively understated.

I really like the ability to switch between music and movie modes too, rather than having to jam the speakers back into their housings to avoid the effects surround sound can have on standard stereo music.

And the use of the satellites when rocking out to your favourite tracks helps create a room-filling musical experience that belies the lack of serious output power behind the B5 itself.

We disliked

When the satellite speakers are in place the Fidelio B5 is a hulking behemoth of a bar. Its length means that if you place it under a 32-inch TV your wee screen is going to look rather dwarfed.

This is a soundbar that’s designed to be paired with the larger displays – which, considering its £600 price tag, isn’t much of a surprise.

Then there’s that certain lack of oomph (technical term) behind the B5 – for the money you might expect a little more output power than the 210W in total you get.

Thankfully the extra spatial sound delivered by the satellites can help to make up the difference, giving the sound a bit more presence – and we are talking about powering a home cinema here, not a three-day free party in the shadows of Stonehenge.

Final verdict

The Philips Fidelio B5 is an impressive bit of kit, and it’s almost the perfect soundbar for someone like me, who appreciates good cinema sound but has no interest in tearing up their living room to install a 5.1 surround sound system which they’ll only use every now and then.

The B5 enables you to pick and choose your movie moments, and do it on a whim. And it creates a pretty decent surround sound experience too, using both Dolby Digital 5.1 and DTS Digital Surround decoding.

The combination of convenience and good audio – the raison d’etre of the soundbar – with its transformative surround sound capabilities makes the Fidelio B5 a great option for the movie fan who can’t face all the aggravation of a proper 5.1 installation.
