Similarities Between the Bose and Sennheiser Headphones

Sound Quality

Bose QuietComfort 35 II Wireless

Clearly, when it comes to headphones, sound quality is of primary importance. There are a lot of subpar headphones on the market today.

These Bose and Sennheiser Headphones, however, both boast superior sound quality. Oftentimes, Bluetooth-compatible headphones will have just one microphone. The Bose headphones have two, and the Sennheiser headphones have three. This translates to outstanding vocal clarity.

Luckily, these Bose headphones and Sennheiser headphones have cushioned, sleek designs, and can be adjusted to sit on an individual’s head snugly.

Differences Between the Bose and Sennheiser Headphones

The differences are just as important as the similarities when it comes to making an informed buying decision. While the Bose and the Sennheiser headphones have some key aspects in common, they have other facets that are completely unique. Some of these are big, like AR capability, and some of them are small, like sound card capability.

When it comes to top-notch products like these, in the end, it comes down to personal preference. To help you with your choice, we will compare and contrast some of the main features of the Bose and the Sennheiser headphones below.

Sound Quality

Both the Sennheiser and the Bose headphones have great sound quality, but one of them is the clear winner all the same. In this case, once again, Bose. You see, these Sennheiser headphones block out sound well, but the audio is altered a bit in the process. Singers, for instance, have been said to have a more nasally tone.

The Bose headphones, on the other hand, are true to sound. They cancel the noise in the area thoroughly and allow the music to really shine.

Sound Cancellation

The Bose headphones, impressively, offer three levels of sound cancellation. The Sennheiser headphones boast adaptive noise cancellation. This is a high-tech feature that is pretty impressive. Despite it, the Bose headphones eliminate out more.

These headphones can block out the engine noise of a plane, and hone in on the audio of your choice. They will also silence a TV in the area. While the Sennheiser headphones still block sound nicely, you will still be able to make out what is being said on TV or the like. This pales in comparison to Bose, clearly.

Ask Alexa

Alexa is everywhere these days! She makes tedious tasks easy. At your word, Alexa will adjust the volume, look up a playlist, play an audiobook, and even check the weather or news. Just ask. Well, these Bose headphones are Alexa compatible. Like AR, is feature is relatively rare! To find headphones possessing both is a steal.

Unlike the Bose headphones, the Sennheiser headphones are not capable of connecting with Alexa. You must turn up the volume manually, and make web searches on your phone, PC or the like.

Alexa saves you the trouble, allowing you to focus on the matter at hand -whether it be music or work. You can keep your hands busy with writing, driving, or whatever else. This is one of the biggest selling points of the Bose headphones, hands-down, and contributes greatly to their winning status in this review.

AR (audio-only, augmented reality)

This is probably what, above all, makes these Bose headphones shine. How many headphones have you had with AR? These headphones not only play sound beautifully, they will also take you on audio-journey. Use AR to learn, play and exercise.

Like most headphones, these Sennheiser headphones lack AR capability.

Contained in the Bose headphones is a multi-directional motion sensor. This is what grants the headphones AR capability. All that you need to do is unlock the AR. There is no motion sensor in the Sennheiser headphones.


These Bose headphones, compared to the Sennheiser headphones, are the most user-friendly. The Bose headphones utilize medium-sized, clearly marked buttons. The Sennheiser headphones, on the other hand, have a tiny touchpad on the right ear panel. This has a lot of complicated commands and combinations… high-tech, sure, but not exactly user-friendly.

USB Sound Card Capability

These Sennheiser headphones can be plugged into your computer for use as a sound card. Improve the fidelity of music and calls on your PC or Mac. This is a unique feature of the Sennheiser headphones.

These Bose headphones, on the other hand, do not double as a USB sound card. Most folks do not purchase headphones for this purpose, so this is probably not a dealbreaker when all is said and done.


These Bose headphones have a 20-hour battery life. This is surpassed by these Sennheiser headphones, which have a 30-hour battery life.

The Bose headphones, however, narrate the battery percentage. The Sennheiser headphones do not; they only inform you with an intrusive prompt once the battery is quite low.


The Sennheiser headphones are about half an ounce lighter than their Bose headphone counterparts. Lightweight is of course always a good feature for headphones to have.

Travel and Storage

Both the Bose headphones and the Sennheiser headphones come with a travel case. The Bose headphones are easier to fold and store. The Sennheiser headphones are a bit trickier to fold, and they have a less compact travel case.

As you can see, the Bose headphones and the Sennheiser headphones share many aspects: storage, sound cancellation, sound quality, and more.

The Bose headphones serve best for music, and for interacting with Alexa, but are also excellent at Wireless Bluetooth calls. The Sennheiser headphones are best for calls and yet serve as music headphones and the like excellently, too.

When it comes down to it, though, the Bose headphones simply have more to offer. The Sennheiser headphones do not have AR or Alexa, and their sound cancellation and sound quality are inferior.

The Bose headphones have these unique features and more So, we’d say, when it comes to the Bose QuietComfort 35 vs Sennheiser PXC 550, the Bose headphones are the clear winner. They are top-quality headphones that you can use yourself or gift with confidence.
