Sennheiser is on a serious roll. The German audio firm recently launched its brilliant Momentum 5, which are without doubt among the best over-ear models I’ve tested this year. Now it’s back with a new pair of earbuds — and once again, Sennheiser has knocked it out of the park. The MOMENTUM True Wireless 5 feel premium from the moment you prise them from the box.

Even the charging case makes an instant impression. It has a reassuringly solid build with a lid that snaps open and shut with a satisfying click. There’s also an embossed silver Sennheiser logo on top, adding another touch of class.

It might sound odd to get excited about a charging case, but I’ve tested plenty of so-called premium earbuds that look and feel surprisingly cheap. That certainly isn’t the case here.

The classy design continues with the buds themselves. They have a nice weight without feeling bulky, while my silver review pair certainly stands out from the ever-growing crowd of boring black and white wireless earbuds.

Sennheiser includes a selection of ear tips in the box to suit all ears, while its companion app features a clever sound test to help you find the right fit and stop sound leaking in.

Once the MOMENTUM True Wireless 5 are firmly in your ears and the music starts playing, the premium experience continues.

Sennheiser has packed a 7mm TrueResponse dynamic transducer into each compact bud — and it shows.

These earbuds sound fantastic. There’s plenty of bass, but it never overwhelms the rest of the track, while vocals and instruments remain crisp and well separated. Even busy songs never descend into a muddy mess.

There’s plenty to play with in the app, too, including a full EQ that lets you fine-tune the sound to your liking.

Then there’s the excellent active noise cancellation (ANC), which does a remarkable job of blocking out the world around you.

I’ve worn these buds on the busy streets of London, the noisy Underground and even on a plane, and they’ve handled all environments brilliantly.

In fact, the ANC is almost too good. When walking around town, I’d recommend switching to one of the ambient modes that lets outside sound in. At one point, I nearly got clipped by a car because I simply didn’t hear it approaching.

Audio quality gets another boost from Snapdragon Sound and aptX Lossless support, while Dolby Atmos with interactive head tracking adds another layer of immersion when watching compatible movies and TV shows.

Calls have also been improved thanks to a redesigned eight-sensor system featuring six microphones, which helps keep your voice clear.

Battery life is impressive, too. You can get around 12 hours from the earbuds before they need a top-up from the case, with around 40 hours of total listening time.

Run them flat and an eight-minute quick charge can add up to another hour of listening.

Perhaps best of all, Sennheiser has fitted user-replaceable batteries in both the earbuds and charging case.

That could make a big difference to the lifespan of these buds, potentially keeping them going long after many rivals would have ended up in the drawer or headed for the bin.

So, are they perfect? Not quite.

My first gripe is the USB-C charging port. It sits on the bottom of the case, meaning you have to lay it flat to charge. It’s not a deal breaker — especially as wireless charging is also supported — but it’s an odd design choice and one that reminds me of the criticism levelled at Apple’s infamous wireless mouse.

The cream-coloured case supplied for my review also picks up dirt surprisingly easily, so you’ll need to give it a regular clean if you want it to retain that box-fresh look.

My biggest frustration, however, is Bluetooth multipoint, which allows the buds to connect to two devices at once.

Unlike AirPods, which seamlessly switch between my MacBook, iPad and iPhone, I’ve had several problems moving audio between devices.

On numerous occasions, after connecting the buds to my laptop, I simply couldn’t get them to switch back to my phone until I went to the Bluetooth settings and disconnected the buds..

Hopefully this is something Sennheiser can iron out with a software update — or perhaps I’ve just been unlucky — but it can become seriously annoying.

Those niggles aside, I’ve got very little bad to say about the MOMENTUM True Wireless 5.

They look fantastic, sound superb, offer excellent battery life and give you plenty of options to fine-tune the audio.

At £249, they certainly aren’t cheap. But sometimes you really do get what you pay for. If you’re a Sennheiser fan and have the budget in your bank, the MOMENTUM True Wireless 5 come highly recommended.

In fact, they may just be my new best buds.
