OnePlus Bullets Wireless Z Bass Edition comes equipped with Bluetooth v5.0 and is fully compatible with all smartphones.
PROS :
1. Sound quality has been amazing. The mid-tones and lows are well balanced and I was able to hear the sound separation pretty well. These earphones are as good as Sony Extra bass wired earphones actually in SOUND QUALITY. Great for watching videos /youtube /Movies /listening to music.
2. Call quality is good.
3. Bluetooth connection quality is good. Pairs quickly.
4. Magnetic power on/off is available. Conserved battery too. But once you put them back into your ears, you have to use the buttons to play your audio again if you are watching videos /music.
5. Buttons are tactile. They perform a variety of functions like - pause/play, forward/backward, call receive /reject, and increase /decrease sound.
6. Comfortable. They really feel good in the ears, no pressure is felt inside the ears even after 5 hours. The quality of the neckband itself is good.
7. Battery life is good. Doesn't really give 20 hrs. More like 15-17 hrs depending on how you use it. Yes, the 10 min quick charge is as advertised.
CONS :
1. Can't pair with 2 devices at once. Sometimes this feature can be a pain when the earphone automatically connects to a device you don't want to connect to, while you're using it on your phone. It's not a deal-breaker.
2. Lacks in-ear detection, basically doesn't continue playing once put your earphones back into your ears. Have to do manually.
3. Had a crackling sound in the right earpiece. Then I reset it. Had to do that a couple of times, and now I don't have that problem anymore. It's working smoothly.
4. Only supports sbc and aac codec. No ldac or aptx support. But it didn't affect the sound quality.
Latency- 100ms Low-Latency Mode, compared to 110ms on the original Bullets Wireless Z. It has a neckband design with a power button on the neckband and has in-line volume and music/call controls. Super Low latency is available for these earphones only if you pair it with a OnePlus 6 and higher edition.
