The Sennheiser HD 450BT wants to change that. It sounds like Sennheiser, but it’s a lot less expensive. It has ANC, which stands for “active noise canceling.” These headphones look great, have USB-C and other modern features, and you can use them for a long time without having to charge them.

We will also compare it to other well-known brands, such as the Sony WH-CH720N. Is this the best active noise cancellation (ANC) you can get for the money? Let’s take a look.

Taking a Closer Look at the Sennheiser HD 450BT

The Sennheiser HD 450BT and the Sennheiser HD 450SE special edition both sound great right away. It was made to sound good without costing too much.

The Best Sound Quality Winner

People know that Sennheiser makes things that sound good. This is true for the HD 450BT. The sound is clear and steady. It can easily play music and podcasts with a lot of bass.

Some competitors make the bass sound better than it is. The Sennheiser HD 450BT, on the other hand, sounds more like what you would hear in real life. People who love music and want to hear it the way the artist meant it to sound will love this. With the Sennheiser Smart Control app, you can change the sound to what you like. Sennheiser has the best studio headphones mixing recording sound quality in this price range.

Comfort: Your Style Should Make You Happy Above All Else

The Sennheiser HD 450BT has the most problems in this area.

This might not be a problem for people with best earbuds small ears. People will say that it’s too tight, though. People say that the clamp is strong and that the ear cups fit over their ears instead of around them. This can make you feel bad and sweat if you listen for a long time.

You should think about this if you want to wear your headphones for a long time. The design isn’t as comfortable or roomy as that of more expensive models or even some of its direct competitors, like the Sony WH-CH720N.

Does ANC Block Out Noise?

Imagine what it would be like if a train, an airplane engine, or an air conditioner were always on. This is where the HD 450BT comes in. It makes the trip to work less stressful.

It doesn’t pick up high-pitched sounds very well, though. People talking, babies crying, and cars honking in the office will still be heard. The Sennheiser PXC 550-II and the Sony WH-1000XM series are the best headphones for blocking out noise. You should know what to expect, but the noise-canceling feature makes it worth the money.

How Easy It Is to Use and Keep Up With

You might need to get used to the Sennheiser HD 450BT headphones. The right ear cup has a lot of buttons on it.

You can talk to it, change the volume, turn it on and off, and skip songs with a button. You might forget what each button does if you don’t look. You have to get used to the buttons before they work. This could be better because some other headphones’ touch controls don’t always work.

How to Charge It and How Long the Battery Lasts

The battery on the Sennheiser HD 450BT lasts a long time. If you turn on ANC, you can listen to music for up to 30 hours on a single charge. This should be enough for a week of driving to work or a long flight.
