These Sennheiser deals are the surprise headphones bargain of Prime Day – but these awesome deals end soon!

Sennheiser Accentum Wireless headphones: was $149 now $109 at Amazon
Delivering active noise cancellation and 50 hours of battery life at a mid-range price, but with the well-balanced sound and strong detail of Sennheiser, these are a great deal if you consider yourself a music purist but you don't have an audiophile budget. They're comfortable and lightweight, too.

Sennheiser Accentum Plus headphones: was $199 now $149 at Amazon
The step-up model in the Accentum range adds fast-charging, angled drivers for superior timing and detail, sound personalization to improve sound further, and aptX higher-res Bluetooth support to make the most of that sound tech. This is the cheapest we've ever seen this model, and it makes a model we already praised a lot in our Sennheiser Accentum Plus review even better value.

Sennheiser HD 600 wired headphones: was $449 now $265 at Amazon
I have a pair of these open-backed wired headphones (that I built myself at the Sennheiser factory…), and they're truly a treat every time I wear them. They have super-plus ear and headband padding so that you can wear them for a while, and that's what you'll want to do, because they're so energetic and dynamic and expansive. Those looking to dabble in the audiophile world won't find better audio quality value than this, though these have fallen to $249 in the past, I should note. It's also a good idea to make sure you have a decent amp or portable headphone DAC to pair them with, but an inexpensive one would be enough for these forgiving cans.

Sennheiser Accentum Wireless headphones: was £149 now £99 at Amazon
Delivering active noise cancellation and 50 hours of battery life at a mid-range price, but with the well-balanced sound and strong detail of Sennheiser, these are fantastic deal for under £100 – it's the cheapest we've seen them. However, I might suggest that it's worth spending the small amount extra for the Plus version – but if you want to be strict on your budget, you won't be disappointed.

Sennheiser Accentum Plus headphones: was £199 now £129 at Amazon
The step-up model in the Accentum range adds fast-charging, angled drivers for superior timing and detail, sound personalization to improve sound further, and aptX higher-res Bluetooth support to make the most of that sound tech. We once saw this model hit £119, so it might drop to that price again over Black Friday – but considering how much we raved about these in our Sennheiser Accentum Plus review at full price, this £129 price is outrageously good.

Sennheiser IE 200 wired earbuds: was £129 now £94 at Amazon
These would be the ideal first step into audiophile territory because they sound simply fantastic and true to the music, and are unbelievably good for under £100. Our full Sennheiser IE 200 review was glowing at full price, where we compared them to more expensive Sennheiser models, and found that these give you so much of the high-end experience. This is the cheapest we've seen them, and we thoroughly recommend them.
