Design & Build Quality


Both OnePlus Bullets Wireless Z and Sony WI-C400 come with 4 different colour options. What a coincidence! But I have a problem with WI-C400’s build quality which I’m coming after colour options.

Other than black OnePlus Bullets Wireless Z comes in 4 different colours РBlue, Green, Orange & White and Sony WI-C400 come in 4 colours РBlack, White, Red (more like pink) & Blue,

The neckband of Bullets Z is made of silicone rubber with a very smooth finish. On the other hand, the neckband of the Sony WI-C400 is made of plastic and not as flexible as Bullets Z.

It just doesn’t have the premium feeling of OnePlus Bullets Z or Sony WI-310 last time we talked.

Overall the design of both is very clean and very lightweight. Bullets Z is slightly lighter than WI-C400. As the design and neckband make it a bit bulkier.

In my personal opinion, in terms of build quality and design, the OnePlus Bullets Z really did a great job at such a low price.


Bass & Sound Quality


OnePlus Bullets Z got the ideal frequency of 20Hz Р20KHz. The ideal range human can hear. While Sony WI-C400 got a frequency range of 8Hz Р22KHz.

OnePlus Bullets Wireless Z and Sony WI-C400 have 9.2 mm & 9 mm drivers respectively. The bass could be identical but since the low frequency is enhanced of Bullets Z bass edition, it sounds deeper.

Sony WI-C400 has a 22 ohms impedance. OnePlus haven’t mentioned the impedance anywhere but guess it will be in the same 16-32 ohms range,

Neither of brands have mentioned the sensitivity so can’t really compare the loudness but I can say both are loud enough.

To conclude, the OnePlus provide much better sound and bass quality compared to Sony WI-C400. Again the winner in OnePlus Bullets Z.


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-C400 has a great battery life of 20 hours but unlike OnePlus Bullets, it takes 4.5 hours to fully reach that limit.

In short, 10 minutes of charge gives OnePlus Bullets and Sony WI-C400 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.


Miscellaneous


Bluetooth Version: OnePlus Bullets Z has Bluetooth 5.0 but because Sony WI-C400 was released in 2017 it has Bluetooth 4.2.

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-C40 is not water-resistant.

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