This also helps in reducing the surrounding sound making it an ideal option to use outdoors or in a public place.

 JBL Duet BT Review: Battery Life

One of the most important attributes of a good headphone is its battery life. No matter how good and advanced the features are, if not for a long-lasting battery, the headphone is not worth picking right? 

With JBL Duet BT wireless on-ear headphones, you need not be worried about the playback time. The headphone has an in-built rechargeable Lithium-Ion battery that gives a run time of 16 hours. This means that you can use the headphones for the whole day or at least for a good number of hours without worrying about putting them on charge.

Factors to Consider Before Buying Headphones

You will see endless headphone options available when you decide to look for one for yourself. Deciding on which one to pick up can be extremely challenging considering so many features and price ranges. Things would have been so much simpler if all the headphones were loaded with all the possible features, and you only had to select the color and the price right? Well, it isn’t always the way we want! So, to make it easier for you, here are a few factors to pay attention to, so you get exactly what you are looking for: 

Which Headphone Style Works Best for You?

There are different styles of headphones in the market. There are two different categories based on wired and wireless headphones. You need to understand which style is most comfortable for you and suits your lifestyle. 

What Do You Need the Headphones for?

Many companies make headphones for different purposes. For example, there are headphones particularly oriented for sports, work, casual use, traveling, etc. This means that these headphones are equipped with various features accordingly. Some headphones are high-end studio-grade and have high-end parts and are categorized under the premium category. If you are into gaming on Xbox, you might want to check out these best headphones for Xbox One.

Wired or Wireless- Which Is Your Type?

Both the wireless and the wired ones have their benefits and downsides. While some may prefer the wired headphones with their incredible and unmatched sound quality, some need wireless so they can move freely doing other works while talking or listening to music. Check the Bluetooth version and the class if you are planning to go wireless. 

Do Heavy Bass and Trebles Matter to You?

Well, if you are an audio enthusiast or are extremely particular about the sound then choose a headphone accordingly. For example, if you are a bass lover, then you should see which headphones deliver a deep bass or have the EQ settings where you can customize the sound settings as per your listening preference. Similarly, if you like a more balanced and neutral sound profile, then go for one that has a well-balanced sound technology for a soothing experience. 

Noise-canceling or Not:

Not all headphones are equipped with ANC. Some may just be designed externally to fit into/on the ear to isolate the external noise. If you are looking for ANC features, then you may need to go for those. 

Check Your Budget:

Different headphones have various price ranges and the price may vary depending on the integrated features in them. If you are looking for a premium feature like the integrated ANC, then you should be open to slightly higher-budgeted headphones. Professional grade headsets are more expensive than regular ones. 

Does Brand Credibility Matter to You?

Well, several headphones feature some interesting technologies/ functionalities that are specific to a particular brand which you may like to go for.  Sometimes cheaper products from unrecognized brands may end up getting damaged soon than the ones from reputed brands.
