If you love making calls with your headphone, it’s probably one of the reasons you’ll love this product. It comes with an invisible microphone for calls. Physically, the headphone is made of plastic, and it feels light. Nevertheless, it is still a solid headphone. It did withstand all the harsh conditions we subjected it to with the controls at the right side of the headphone. Also, we got confused a couple of times regarding which ear is right and which is left. Nevertheless, it was easy to navigate the control as you could easily tell which button does what.

One of the ways this headphone differs from its competitors in the same range is the sound quality. Although the bass it produces is not perfect, even for its price, the mid and treble are amazing.

Review methodology:

The Sennheiser HD 4.4BT comes in a regular black box. We’re not sure if the box is eco-friendly as the manufacturer didn’t specify it. On the rectangular box is splatter information about the spec of the headphone. Other details are also written all around the box.

Unboxing these headphones doesn’t require rocket science. You need to open the box the regular way you open other product boxes and, viola! You are in. Once you open the box, you’ll see the headphone and a few other items casually lying in a transparent plastic holder. Aside from the black headphone, you’ll also find a soft carrying couch, a 2.5 mm to 3.5 mm cable, and a leaflet filled with warranty information.

When it comes to reviewing wireless headphones, we are the best, and we’ll tell you why. Wireless headphones fascinate us, and we made it into a hobby to always check out any new wireless headphone model that’s released in the market regardless of the brands. While we sometimes receive special requests from the brand to test and check the new headphone model, we purchase others from our pocket.

Now we’ve prided ourselves in testing headphones, observing how it looks, what it sounds like, and if it truly meets the standard set by the brand itself. Of course, we do not do this in a vacuum, but wireless headphones are supposed to meet based on their price points within the context of the standards.

We take these headphones through the highs and lows, subjecting it through various testing methods and models to be 100% sure of the functions it delivers. Our research methods are pretty practical. Our experts ensure that they experience the models first hand and for months so that they can boldly note down their discovery.

For instance, when a brand calls their headphone noise isolation headphone, we take it for a walk in the crowd to be certain that the noise isolation feature actually functions at the level the manufacturers claim it does. If it’s waterproof, we take it for a run and do rigorous exercise that makes our experts sweat profusely.

We do it for a while and observe the headphone’s reaction to it. Once we are certain, we put our discovery into writing. Now that you know our review methodology, let’s dive into our test results on the Sennheiser HD 4.4BT wireless headphone.

Sennheiser HD 4.4BT features

Sound Quality

The sound quality is excellent for the price range. It produces a bass, mid and treble sound range. Although the bass sound isn’t perfect, it is pretty good, and you’ll enjoy it more when watching a movie. However, if you enjoy getting that bass hit that high-end headphones produce while listening to music, you might not like the bass this headphone makes when playing any music. The treble and mid-range come out smoothly, nicely, and it’s enjoyable. Overall, it produces clear and crisp sound quality. 

Noise Isolation

This headphone deploys noise isolation property. When we tested the extent of its noise isolation feature, we realized that it fairly isolates you from the noise in your environment. Now, don’t get discouraged because we used the word ‘fairly.’ Here’s what we mean. On a plane, bus or car, the headphone pretty much isolates you from the noise. You most likely won’t hear the noise around. If you do, it would be minimal and not intrusive. The best part is, we also tried to see what the noise isolation feature was like with no music on. Of course, we could still hear the noise, but it was much quieter.

Wireless Connection

The wireless Bluetooth connection is perfect for the price range. Once you connect your phone to the headphone, you won’t encounter issues with disconnection, except when the battery is extremely low.

Benefits

  • An impressive benefit of this headphone is the battery life. After charging for two hours, you can go an entire day without charging it as the battery life lasts up to 25 hours. But we noticed that the battery lasted for more than 25 hours when we didn’t increase the volume to the highest.
  • With these headphones in use at a certain level, you would enjoy blocking out every noise in your surroundings.
  • The headphone is also comfortable. With the earphones and headband padded, you’re in for a manageable level of comfort. Manageable because it might start to get uncomfortable after wearing it for extra long periods. You can also adjust the elastic headband to fit your head shape.
  • The materials used to forge this headphone is solid as it can withstand any harsh condition or treatment (not that you should treat it badly, though)

Drawbacks of the product

  • Surprisingly, Sennheiser didn’t make this headphone compatible with YouTube and Audible. So, if you play most of your music from YouTube or Audible, you might not enjoy using these headphones at all unless you have an alternative music streaming platform.
  • Although it brings a level of comfort, the ear pads are not as wide as we would have loved them to be. If you purchase this, though, you might be comfortable with how wide it is.
  • You can only use the control buttons and slider on the right ear cup when the headphone is connected via Bluetooth.

Verdict

Generally, the Sennheiser HD 4.4BT headphone is a good deal. It offers amazing value at the price it goes for. With the elastic headband padded enough to give you comfort, its general durability, and long-lasting battery life, you sure are in for a treat. If you are on a budget, you should definitely opt for these headphones. It is quite affordable and impressively functional. Although the design doesn’t exactly look flashy, the audio quality would leave you feeling satisfied.
