I have been using Sony Xperia Z2 for now long time. I will try level best to get you the insight of the phone and specification. Honestly I love the phone.
Sound Reception: I personally feel the sound is very low on the open atmosphere and you need a headphone or headset to keep with you and the sound works goods. It has mono speakers which makes a sound very low and thin without using the headphones. But with the best headphones you can easily enjoy and it does a sings goods to your ears so I would rate the sound reception process on average consideration than other models in the market. My personal rating on Audio for this phone is 4/5
Ease of Use: Sony has its own interface and it easy for me to navigate, more or less it’s the same interface like many other android available in the market.
Style & Design: Its Simple and Elegant, Glass design makes its premium feel but, yet lets to finger marking which is annoying fact. Yet I love the design. I would rate on design 4.5/5
