Until now, we studied these products individually to figure out what they have to offer. However, that still might not make the choosing process easier for many as these products are equally strong on paper, offering solid features.

As a result, we are going to compare the Sony XB 400 vs OnePlus Bullets Z so that you get a better understanding of the differences that separate the two. Therefore, here is a detailed comparison for Sony XB 400 vs OnePlus Bullets Z on the basis of the below-mentioned parameters

1. Design and Build Quality

As discussed, both these headphones sport an ergonomic design and exhibit an excellent build quality. But when we dig deep into this parameter, we see that the Bullets Z comes with three colours whereas the Sony XB 400 only has 2 colours to offer. Meanwhile, the XB 400 comes with a neckband that can be adjusted as per the user’s needs.

On the other hand, the Bullets Z weighs only 40 grams, making it lightweight, comfortable, and extremely compact to fit into small spaces. In simple words, both these in-ear headphones have a premium design and durable build quality. However, lightweight headphones such as the Bullets Z are perfect for long hours of usage as they are flexible.

2. Sound Quality

The primary purpose of every headphone is sound quality. Therefore, it is vital that you pay detailed attention to this feature. Merely having a large bass driver does not guarantee the best sound quality as the headphone needs to have the power that matches it.

Banking on this, the Sony XB 400 comes with 12mm drivers that pair well with the overall power to deliver an immersive sound experience. Meanwhile, Bullets Z has a 9mm driver in place. In terms of sound quality, we suggest you go with the XB 400

3. Features

If one needs to get the most out of their headphones, then they shouldn’t compromise on the features. But this is one criteria wherein both these headphones are equal in comparison. Both the XB 400 and the Bullets Z come with Bluetooth v5.0 connectivity that allows for quick, strong, and stable connectivity within a 10-metre radius.

Unfortunately, unlike the Bullets Z, the XB 400 isn’t sweat or waterproof, making it susceptible to early damage. Similarly, the XB 400 does NOT have active noise cancellation which genuinely puts Bullets Z in the lead.

4. Battery Life

Your headphones are only as good as the battery they come with. But with the quick charge feature, you now get a runtime of 10 hours in just a 10-minute charge with the Bullets Z. On the other head, the XB 400 only gives you 60 minutes of runtime on a 10-minute charge.

However, when fully charged, the XB 400 and the Bullets Z offer 15 hours and 17 hours of runtime. The XB 400 takes around 2 hours to charge fully whereas the Bullets Z requires only 50 minutes.

5. After Sales Service

Despite their impeccable architecture, both these headphones are susceptible to damage. Therefore, you must pay due attention to the after-sales service. Both these products have a concrete after-sales service that will respond to your grievances at the earliest. Similarly, both these brands have their service centres established in multiple parts of the country that will address your concerns promptly
