First Impression for OnePlus Bullets Wireless is “Not So good”.
4000 Rs is fair price in India for an ear-phone. For that price point Build quality is OK and very light weight. It comes with type Charging port, thumbs up for that. It has aptX (In digital audio data reduction technology, aptX is a family of proprietary audio codec compression algorithms owned by Qualcomm.) Losses are less in this codec technology. Call Quality is also good. In terms of Sound quality for Music Mid and High frequencies are good but lags in Low Frequency means Bass. I tested with Poweramp music player and keeping Bass in below Mid level in Tone Setting, sound started cracking. Also it can connect only one device at a time. These days cheapest headphone comes with two device connectivity. here we have to disconnect first device to connect other device which is very disappointing. Battery life is also not as advertised. although it charges quickly with dash charger comes with OnePlus mobiles.
