These earphones have great bass quality. Once again sony's performance is up to the mark. Better than almost every earphones in the range of 7k. Battery also good. You can use it whole day long. No drawback till now. BOUGHT THIS AFTER A LOT OF RESEARCH.

This is it, Bass Daddy of Bluetooth Earphones..

Bluetooth earphones always fall short of that thumping bass, I am a Fan of Sony XB series because i mostly listen to Trap and anything with Bass, i bought these to replace the Flagship XB75AP, The key word in my purchase decision was the 12mm drivers, However i Still Wasn't sure if these will perform the same as the XB75 but when i started using them, these blew me off my Zone, What an awesome pair of earphones. USB type C and Bluetooth 5.0 is double Icing in the Cake... If you are into Anything BASS Close your Eyes and click on Buy Now...

Headphone Zone Was Soo quick with the Delivery.. i ordered them yesterday Got them Today... Plus i got the Best Price here...

Good but Over Hyped product

- The audio from these earphones is good. Not that bass heavy but good enough to produce that thumps. I would give 4 stars for sound
- Battery life is great when compared to other products in this price range. 5 stars for battery
- Built Quality is at the down side. Although buttons are well placed and gives you touch feedback, the plastic seems to be bit cheap (looks like the material used in the products < 2k)
- Another major concern is that there is no audio filter mesh at the ear tips. The sound will directly hit your ears and over the time dust can easily get into your buds.

Just awsome

this earphone excels in both sound quality and performance, if you are music lover just like me... this delivers just the same u expect with its tremendous 15hr battery and superior call quality accompanied with the Sony's 12mm driver set up, u have no blind spots.

Bluetooth with

Wireless Range

You must have most likely noticed that wireless signals do not travel an infinite distance. The farther a wireless signal goes, the weaker it gets. This loss is known as path loss, and it defines the range of connectivity. This range of connectivity is dependent on the wireless protocol in use like Bluetooth. Three classes offer standard ranges of connectivity with Class 1 devices transmitting at 100 mW with a range of 100 meters or 328 feet. Most Bluetooth headsets and headphones are Class 2 devices that transmit at 2.5 mW with a range of 10 meters or 33 feet. Lastly, Class 3 devices transmit at 1 mW with a range of fewer than 10 meters.
