In a Nut Shell:
Bose QuietComfort 25 vs 35 – If high-quality sound, digital assistant support, and wireless are important to you, then the Bose QuietComfort 35-II is the best model for you to buy. Being able to walk around for up to 33 feet / 10 meters with your headphones on is a convenience that should never be underestimated.
However, if you want an admirable brand name, high-quality, and don’t care if your headset has wires, then go with the Bose QuietComfort-25 instead. You will save enough on the price tag, and the audio performance between the two models makes it barely noticeable.
The Bose QuietComfort35-II headphones are the pinnacle of Bose audio technology and you would find them hard to beat against any competitor. Bose QuietComfort-25 is priced to be accessible to a wider and more budget-conscious audience, and there are minuscule performance differences between the two that make a difference depending on your audio requirements.
You’d be forgiven if you got the Bose QuietComfort 25 Acoustic Noise Cancelling Headphones and the QuietComfort 35 Wireless Headphones II mixed up from just looking at them. These Bose products are the same size and have the same basic design. Is there a difference between the two headphones where it counts: performance and audio quality?
This review is here to find out the difference between the Bose QuietComfort 25 vs 35 Wireless headphones. Which one is best? The Bose QuietComfort 25 vs. 35 begins here.

Bose Headphones
Think noise-canceling: Think Bose. The Bose Corporation has been dominating the high-quality audio equipment market since Amar Bose first redeveloped the home stereo system. The Bose calling card through the years has been building the most outstanding noise cancellation tech in the audio world, as well as producing headphones that make sounds great.
If you are on this page to find out if it’s worth it to dig deeper into your pocket for the Bose QuietComfort 35-II or settle for the Bose QuietComfort-25 instead, that’s where this Bose QuietComfort 35 vs 25 review can help you.
Design
Let’s discuss the most obvious difference between the two headphones: the QC-35II is wireless and the QC-25 is wired. Bose makes this distinction clear in the product descriptions. As anyone who has used wireless headphones will happily state: wireless headphones are so convenient to use and they make sense when desktop mice and keyboards are free to move around the room with you now too.
The fact is though, wired headphones deliver better audio. Is it possible that Bose has managed to crack this conundrum with the QC35 II? Back to the design features of these two products, they are similar and can only be distinguishable from one another because one has wires (QC-25) and the QC35-II has a slightly more serious tech appearance.
Comfort
Both headphones are lightweight and have been designed to be worn for hours without discomfort or irritation. The place where noise-canceling headphones are worn, such as public transport, study rooms, and dorms are made bearable thanks to the chunky padding applied around both of the ear cups. The clamp setting grip tight enough to remove other sound waves from penetrating, but not hard enough to give the wearer a headache.
Both the QC-25 and QC35-II provide excellent levels of comfort for hours.
Sound
- The midrange audio performance of both headphone models is well-tuned.
- Warmer tonality has been added to both headphones’ low to mid-range levels.
- Effective high to mid-range levels give guitar and vocal production mixes a nice edge.
The most significant difference between the two headphones in this review deals with the high-end sound. The QC-25 has a pure, immediate delivery which is hard to match. This is because it isn’t wireless.

Noise Cancellation
Both Bose headphones offer cutting-edge noise cancellation capabilities. This makes them perfect for public places or anywhere you need to concentrate, sleep, or be peaceful. The QC-25 and QC35-II are the best devices on the market when it comes to noise cancellation.
This is why the Bose brand is considered the only audio equipment choice for consumers who are serious about blocking out noise. Sony WH1000-XM3 matches Bose for sound delivery, but Bose dominates when it comes to noise cancellation. Between these two models – the QC25 vs QC35 – there is no difference in the product’s ability to block out noise.
Performance
The Bose QuietComfort 35-II headphones and Bose QuietComfort-25 headphones both support Bluetooth. This means that both models get comparable connectivity between them. They provide a listening range of approximately 33 feet (10 meters), but performance-wise, there is a massive difference when it comes to each model’s battery life.
The Bose QuietComfort-25 model headphones provide a solid 35 hours sit-in for the life of one solo AAA battery. That’s an impressive amount of sitting-in and is easily enough juice for a long-haul flight. The Bose QuietComfort 35-II headphones function for up to 20 hours when set in wireless mode. This time frame can be expanded considerably by using this model in wired mode, up to 40 hours.
If you’re content to use your headphones in wired mode during an extended trip using public transport, then the QuietComfort 35-II offer a longer time frame.

Extra Features
If you are continuously using your device to operate Siri or Google Assistant, the major difference between the Bose QC25 vs QC35 II is that the QC 35-II offers digital assistant support. If you find being able to activate functions by simply saying “Hi Siri” out loud, then you should find this extra feature the QC 35-II offers very helpful.

In Conclusion: QuietComfort 25 vs 35
It’s hard to make a judgment call on which headset you should buy. If the highest quality sound, digital assistant support, and wireless is important to you, then the Bose QuietComfort 35-II is the best model for you to buy. Being able to walk around for up to 33 feet / 10 meters with your headphones on is a convenience that should never be underestimated.
However, if you want an admirable brand name, high-quality, and don’t care if your headset has wires, then go with the Bose QuietComfort-25 instead. You will save enough on the price tag, and the audio performance between the two models makes it barely noticeable.
Bose has always provided value when it comes to getting enough bang for your bucks. If you want the best noise cancellation, these are the headphones you need. If you want wireless, then it’s definitely worth shelling about a bit more for the Bose QuietComfort 35-II.
