OnePlus Bullets Wireless Z vs Sony WI-C310

OnePlus and Sony are some great brands. I barely need to introduce either of them to you.

But when you get to choose from two very popular brands, it’s very normal to get confused. That’s why I’m writing this article to help to get the best deal.

This Oneplus Bullets Wireless Z vs Sony WI-C310 ultimate comparison article will go deep into each earphone and include all the things you need to choose the right one for you.

So, let’s dive in.

Design & Build Quality

Both OnePlus Bullets Wireless Z and Sony WI-C310 did a great job in terms of design. Both offer some cool colour options but the original solid black is good enough.

Other than black OnePlus Bullets Wireless Z comes in 4 different colours (Blue, Green, Orange & White) and Sony WI-C310 comes in 2 colours (Blue & Gold) aside from black.

The earbuds of both have a strong and durable metallic finish but it often makes earphones heavy. OnePlus got a very unique shape while Sony chose to go with the regular shape.

The neckband of the Bullets Z also feels very smooth even though it’s made of silicone rubber.

On the other hand, the neckband of Sony looks the same as the flat cable with a matte finish. Bluetooth earphones with flat neckbands tend to be lighter.

Both of the earphones are equally good in terms of design and build quality. But in my personal opinion, Sony Wi-C310 looks better because of the finishing and the overall design.

But everyone has their taste. Also, Sony WI-C310 is a lot lighter than the OnePlus Bullets Wireless Z, which increases comfortability.

In this section, both are good in their own way. Just listen to your taste.

Bass & Sound Quality

To begin with, both have the ideal frequency response, 20Hz – 20KHz.

Sony WI-C310 & C400 are very similar in specs and sound quality. OnePlus Bullets Wireless Z and Sony WI-C310 have 9.2 mm & 9 mm drivers respectively

Thanks to the bass enhancement the bass edition of Bullets Z produces much deeper bass now and of course deeper than WI-C310.

The same goes for sound quality as well. Sony WI-C310 has a 24 ohms impedance. Not sure about the Bullets Z due to lack of information.

Not sure about the sensitivity of either of them but I guess both are lower than 100dB SPL (Sound Pressure Level). Most budget Bluetooth earphones have 96dB-98dB SPL/sensitivity.

Bullets Z is cheaper but and the sound and bass quality is way greater than Sony WI-C310. So, you know who’s the winner of this section.

Battery Life & Charging Time

This is the thing I like most about OnePlus Bullets. Charge for 10 minutes and you are good to go for 8-9 hours straight. OnePlus say it is 10 hours but it varies a bit on the usage. The max limit of battery backup is up to 20 hours.

On the other hand, Sony WI-C310 has a great battery life of 15 hours but unlike OnePlus Bullets, it takes 3 hours to fully reach that limit.

In short, 10 minutes of charge gives OnePlus Bullets and Sony WI-C310 10 hours & 60 minutes of battery life respectively. A day and night difference.

Remote & Functions

Both earphones have a remote and mic with all the necessary buttons to pause/play songs, control the volume, and power on/off.


Bluetooth Version: Both come with Bluetooth 5.0 that is compatible with all the latest devices with a 10 meters range.

Water-Resistance: OnePlus Bullets Wireless Z is IP55 sweat and water-resistant. An ideal choice if you want to use it during exercise. Unfortunately, Sony WI-C310 is not water-resistant.

Accessories: Both provide a USB-C cable for charging, earbuds of different sizes, and all the required papers like the manual, warranty card, etc.
