What are people's opinion on the best xb1 headset? Value for money is the main focus for me. I'm looking at turtle beach xo4, xo7, astro a40 or a50. Leaning towards the xo4 at the minute. Xo4 are about 60 euro, xo7 are about 90 euro. A40s are about 140 euro and there's a deal on a50s near me for 170 euro until Monday.
