Quite disappointed, especially as priced as a premium product. They also stick out of ears too much.

I bought these after reading the WhatHiiFi review. The sound is great for in ears, it’s just all the other issues ruin them. They would be great for home use only, as noise cancelling is useless. I travel every week using planes, trains an metro, I ear everything. I was told by Sony that these would be effective for numbing down these noises, which they don’t. Then there is the constant right earbud losing connectivity while walking in a public space. Again Sony said that this is because 2.4g WiFis frequency of stores WiFi and other people’s phones. Hence my reason they should be for indoor use only, as they don’t function outside in the elements. Then the battery is only 3 hours, which isn’t so bad if you at home and normal commute. But for travel it’s a no go.. It takes 1.5 hour recharge them. FYI Apple EarPods recharge in 15minutes. Sony did come back to me, and told me they will have connectivity 2.4 G Frequencies of other peoples devices in stores Wi-Fi as well will affect the earbuds connectivity. (Apple EarPods don’t do this btw). So they are great sounding earbuds, but poor connectivity in public areas.

I'm amazed at the sound of these headphones for music playback. They're almost as good as my old set of Shure 525's for playback of the the ACC files you get with Apple Music and much more convenient. Using them to take voice calls however was and continues to be a disappointment. When the phone rings the right unit stops sounding and you hear the call in mono only from the left unit at a much lower apparent volume (probably because it sounds exactly the same as it would if you tried to listen with only one unit in). Also my voice (apparently) sounds weak and muffled to the other participants in the call (which doesn't surprise me bearing in mind the poor quality of my user experience using them to listen to the call). For professional calls this makes them unusable and I find myself having to whip them out my ears and use my phone or quickly plug a wired headset in which defeats the object completely. I'm keeping my fingers crossed that this will be fixed with a software / firmware update as you wouldn't expect this from such a premium product. The only other problem is that they can work loose in the ear and fall out - this has happened to me a couple of times whilst walking. An easy fix for this would be to include compression foam inserts that can mould to the contours of the inner ear and hold them in more than the ones that currently one with the product. I use these on my Shure for the same reason and I'm currently scouting around to see if I can get some for the Sony.
