Below, 7You reveals the models to invest in.

ACCENTUM Wireless Headphones $139 (save 54 per cent)

Sennheiser’s ACCENTUM range has always punched above its weight in my opinion.

And the ACCENTUM over-ear Bluetooth headphones are no exception.

They have a 50-hour battery life, great noise-cancelling and a great Bluetooth dongle to make connecting to your computer easy and super stable.

Out of the box they sound fantastic (no surprises here) but if you like to tinker with your EQ the Sennheiser Smart Control Plus app will give you five-band EQ, customisable sound zones and a stack of other personalisation options to get your sound just right.

The ACCENTUM Wireless headphones normally retail for $299.95 which is already a steal but as part of the Prime Big Deal Days sale event you can snap up a pair for $139.

These are a great option for someone who is looking for a new pair of headphones which wont blow the budget.

Momentum 4 Wireless Headphones $259 (save 55 per cent)

Hot take — the Sennheiser Momentum 4 Headphones are under-rated. 60 hours of battery life, aptX Adaptive audio, clean modern design... Really great pair of headphones.

The Momentum 4 Bluetooth headphones were first released around four years ago and they still hold their own against more expensive newer models.

They deliver very good noise cancelling and the 42mm drivers open up the sound signature to hear more detail in your music.

The Smart Control Plus app again lets you get your settings just right and the 60 hour battery life is backed up by fast charging so long flights and commutes are a done deal.

The Sennheiser Momentum 4 Bluetooth Headphones normally retail for $579.95 but right now you can get them for just $259 on Amazon.

HDB 630 Premium Bluetooth Headphones $749 (save 25 per cent)

These are the best sounding Bluetooth headphones on the planet. I will die on that hill.

If audio quality is the most important thing to you and you don’t mind forking out a bit extra then I honestly couldn’t recommend these any higher.

Sennheiser set out to bring audiophile level quality to a wireless pair of headphones and seriously they nailed it.

One of the biggest things I look for in the upper end of headphones is clarity and separation between instruments and they just knock this out of the park.

The HDB 630 supports super high resolution audio and the included BTD 700 transmitter unlocks that quality for more and more devices.

Seriously I cannot speak higher of these headphones, the only thing that stops me from recommending them to more people is the usual thousand dollar price tag.

But $749 while still a big investment, is a lot more approachable and a great opportunity to treat your ears to some stellar sounding headphones.

What is Amazon Prime Big Deal Days?

Amazon Prime Big Deal Days is Amazon’s major fall shopping event designed exclusively for Prime members, offering deep discounts across dozens of categories ahead of the holiday season.

Often referred to as “Autumn Prime Day”, the event serves as a kickoff for holiday shopping, similar to the summer Prime Day event.

It comes as a precursor to Black Friday and Cyber Monday discount periods.

Discounts span more than 35 categories, including consumer tech, Amazon devices (Kindle, Echo, Fire TV), fashion, beauty, home and kitchen goods, and toys.

Major participating brands include Shark, Sony, Lego, Dyson, KitchenAid, and more.

This year’s Prime Big Deal Days gives savvy Aussies seven days to find savings across the brands and categories they love most and make their dollars go further – whether that’s getting ahead on Christmas gifting, stocking up on pantry staples, or treating themselves to something they’ve been eyeing for months.

New research from Amazon Australia has uncovered the “deal threshold” that tips Aussies from browsing to buying, with seven in ten (70 per cent) saying a discount of 30 per cent or more is their tipping point to make a purchase.

Nine in ten (90 per cent) Australians plan to hold or cut their Christmas gift budget this year, and more than half (56 per cent) are planning to stockpile everyday essentials such as groceries due the cost-of-living crisis – with half (49 per cent) expecting their weekly grocery shop to rise by $100 or more over the festive period.
