Best headset I’ve had ever in my life

I’ve been wanting this head set since 2014 and I was able to finally get it in 2016 when the Tr’s came out and I got them at Pax east for a deal. I’ve owned for 2 years now and it’s the best gaming purchase I’ve ever made. I would recommend getting a mod kit because the ear cups and mic and such is way better and more compfy. This is coming from a 16 year Old and these are awesome I would recommend these if you sit down in front of a desk or close to a tv. Wish they had a A50 Tr that would be awesome. OVERALL: You won’t regret this purchase most comfortable and stylish and customizable headset way worth for 250$!

Best headset I’ve ever bought

I have been waiting to do a review on these for two years now I wanted to know how good they were and how long they’d last, let me start off by saying these are very comfortable and durable I’ve dropped them several times and they still work like they Day I brought them out of the box. The mix amp software that comes with it is absolutely in credible I have 3 custom mixes that I use for my favorite games and they all isolate footsteps whilst being able to hear pins drop that’s just how good the sound quality is and how well everything flows together between the headset the mixamp and the software, I was a tritton fan boy and I was gonna buy their tritton katana headset but instead I went with the Astro a40 TR’s and I’m so glad I did, this headset is so comfortable and lightweight it’s perfect for long gaming sessions I’ve hit 10+ hours and still felt like I’ve been able to wear them if I wasn’t getting sleepy this is a 100% honest review I’m not here to sell people out I’m telling you why you should buy this amazing headset because it’s just that AMAZING!!!!

A40 TR

So far the A40 is awesome had to for 6 months and without the mixamp the headset is useless.

Amazing product

Great headsets haven't got any issues yet with the product ill keep and up date over time

Mix amp to headset wire

I love the headsets. But mine fell off my desk and broke the cable so I went to use a regular aux cable but it didn't work because the jack is different. Now I have to spend money unnecessiarily to fix it instead of using one I had.
