Never had a headset like this before and it blew my mind on how well it sounded.... my heart is still racing from playing black ops 4 and battlefield 5 with these... it’s so clear and sounds amazing!!! Great job Astro!!! I will recommend these to my friends!

Buy now you won’t regret it

I’ve had this headset for about a year now maybe a little less maybe a bit more but I will assure you this is the best headset you will ever buy, I usually get a headset and the game sound is great but the mic quality is terrible or vice versa, these have best of both worlds, battery charges overnight and I can play an 8 hour day and still won’t be dead and will still be coftorable on my head. Bottom line these are great headphones, never had a problem with them in over a year.

As Expected

Easy to set up, great quality, game and voice chat exceptional at this price point and works seamlessly. As I expected from Astro and hasn't disappointed, thank you Astro.

Amazing Value

It's been over a year since I've used a nice headset. I have experience with the A50s which were amazing and comfortable. The sound is close to the A50s, however they aren't quite as clear and don't have as much bass. All things considered for the price they are an amazing value. I work for an electronics store and Turtle Beach headphones come in broken ALL the time. I rarely see Astros with the issues TB's have. For the mid-tier priced headphones I am in love with the quality, comfort is good enough for me, and the cherry on top is Dolby Atmos support. Thank you Astro for expanding the product line.

Almost perfect

I have been using these for about a week now. A few issues but well worth the money! The first issue is that i wish the master volume was a bit louder. I mean there not low just not blasting lol. The second is even though they feel comfortable when i first put them on , they start to hurt my ears after an hour or so. Im hoping when i break them in will get better. The third issue is that on the default setting there is a small amount of white noise when the mic is flipped down and game is completely quiet. However if you connect to acc and lower the mic monitoring(i think its called side someting) just a little that noise goes away. And still plenty of mic monitoring. So over all a great set and def worth the money. Especialy at 119.00!!
