Sennheiser gives its flagship true wireless earbuds a full revamp, complete with Bluetooth 6 and replaceable batteries

Sennheiser has announced the Momentum True Wireless 5 noise-cancelling earbuds with a completely redesigned enclosure New features include Bluetooth 6.0, Dolby Atmos and replaceable batteries Available to buy from September 3 for the same price as the previous generation in the US, but more expensive in the UK and Australia Hot on the heels of the launch of the much-anticipated Momentum 5 Wireless over-ear headphones, Sennheiser has announced their flagship earbud sibling in the Momentum True Wireless 5.

While there was a five-year gap between generations of the over-ear cans, we’ve thankfully had to wait less than three years for the sequel to a pair of earbuds we’ve previously awarded 4.5 stars to — and this is speedy indeed considering they’re a complete revamp over the fourth-generation true wireless buds, including design and features.

The fifth-gen earbuds introduce a “barely there” fit, by way of a newly streamlined silhouette.

The audio brand promises that the new design is more comfortable than the previous generation, and I’m certainly keen to test that claim, especially since the previous model was “comfortable enough to keep wearing” even “after several hours of continuous use”.

Four ear-tip sizes are included to help users achieve the perfect seal, ranging from extra small to large.

Ensuring customers get a similar experience whether they go buds or cans, Sennheiser says the Momentum True Wireless 5 benefit from the “same sound-first DNA” as their over-ear sibling.

To achieve that goal, the new in-ears are fitted with the brand’s 7mm TrueResponse dynamic driver that claims to balance “remarkable detail with full-bodied, bass-driven tuning”, alongside “exceptional precision, clarity and dynamics”.

While Bluetooth 6.0 is still very much a rarity in the world of headphones, it has already found its way into a range of devices, including the iPhone 17, Google Pixel 10 and 11 and Samsung Galaxy S26.

While they’re not the first set of headphones to integrate the latest standard (the JBL Tune 530BT and 730BT also boast Bluetooth 6), they’re certainly part of a minority group at present.

Sennheiser is evidently keen to champion the latest wireless connectivity, as the Momentum 5 Wireless over-ears have also been promised Bluetooth 6.0 via a future software update.

The active noise-cancelling system in the fifth-generation flagship earbuds have also been revised.

This sees a redesigned ear tip working in tandem with a four-mic array (per bud) to "maximize noise cancelling performance”.
