Don't miss these stunning Sennheiser headphone Amazon Prime Early Access deals - you could save up to $200

Sennheiser Momentum 2 Wireless | $299 now $149 at Amazon

Sennheisers entry into the true-wireless in-ear headphone game is a very, very good one. The noise-canceling is excellent, and the sound quality vibrant and crisp. They are usually a very expensive option, setting you back around $300. At the moment, the Amazon Prime Early Access Sale has chopped off around $150, so they're quite a bit cheaper.

Sennheiser HD 350BT | $120 now $70 at Amazon

They may not come equipped with noise-canceling, but they sound great and Bluetooth connection is, as always, extremely convenient. They'll also last a nice long 30 hours, giving you plenty of listening time when you're out and about. In the Amazon Prime Early Access Sale, you'll save $50 off full price, bringing them comfortably under $100.

Sennheiser HD 599 | $199 now $90 at Amazon

These are not headphones for outside - anything but. They are wired and open back, which means everyone around you will hear everthing you're listening to - and it won't even be muffled. Hope your fellow bus travellers like Britney. Use them at home though and you'll have one of the best sounding headphones for under $200 - only if you buy them now, you'll have paid less than $100.

Sennheiser CX Wireless | $129 now $70 at Amazon

Sennheiser's entry-level wireless in-ears sound phenomenal, and while they don't have inbuilt noise-canceling, they'll still do a good job of making sure you hear less of the outside world. They're pretty friendly on the wallet even when they're full price, but they're now under $100 in this Amazon Prime Early Access Sale.

Sennheiser HD660 S | $499 now $299 at Amazon

Like the 599 above, these aren't a pair of headphones for the bus. They are also open-back audiophile headphones, except these ones are a fair bit more expensive. They're also some of the best sounding headphones ever made and when you stick them on, you'll wonder how you managed without them. Every other pair of headphones will sound a bit crummy.

Sennheiser CX Wireless Plus | $180 now $110 at Amazon

The plus in the name means they've got extra features, such as noise canceling. They'll be great for the bus or walking through town, and with $70 off, they more affordable than ever. You can choose your color too - there's Black and White.
