Rosewill Active Noise Cancelling Wireless Bluetooth Headphones - ANC Over Ear Headset with Long Battery Life, Hi-Fi Sound for Travel, Work & Gaming | Perfect for Commuting, Office & Home Entertainment

I paid about $20 for these H9000s. I also own the Anker Soundcore Q20s (paid $35) and SkullCandy Venues (paid $100). Here is my comparison:Build quality:My Anker and SkullCandy headphones are definitely superior to the Rosewill H9000 when it comes to build quality. The H9000s are much more rigid in their movement when twisting/folding/adjusting. The ANC switch seems kinda flimsy and the buttons feel cheap compared to the Q20s and Venues. the padding isn't as soft and material doesn't feel quite as supple (although it does still feel really nice). For the price I paid though, the build quality is still fantastic.Comfort:These came in yesterday and I wore them for about 7hrs before bed. I didnt have any discomfort at all. they feel great actually. i put them on again when i woke up and have had them on for another 4 hours or so today. the ear padding isnt as soft as the Q20s, but i actually prefer that they're a bit more rigid. sometimes with the Q20's softer padding, my ear touches the inside of the phone and causes discomfort after a while. i dont have that at all with the H9000s. I mentioned that the fabric/leathery type material isnt as supple on the H9000s, but theyre still very comfortable and feel fine against my head. I dont have that issue with the Venues either, they have pretty rigid, thick padding.Sound Quality:This is where i was most impressed with the H9000s. They seem so much more crisp than my Q20s and Venues. I only listen to spotify and amazon music and have them set to full quality, but the stream quality is still kind of low. i also have my spotify sound mixer set for my ears/to my preference. that being said, the bass and treble seem to be noticeably richer on these H9000s. Theyre not insanely loud, the highest sound level doesnt seem to be too unsafe, but they get loud enough for me. Theyre just as loud as the Q20s and Venues, if not a little louder (maybe do the richness of the sound). The Q20s and Venues seem a bit muffled compared to the H9000s. They have plenty of bass and the bass is super crisp.Call Quality:I've made a few calls and havent had any issues. These definitely seem to bring more treble out of everything (music / calls), so i feel like my calls sounded a bit clearer than usual. maybe i can update this as i have more calls.ANC:It works. Can definitely tell when its turned on. Drowns out the sound of my refrigerator at least. i havent traveled with them yet but i dont see why they wouldnt work fine for plane noise reduction. again, the switch seems a little flimsy, but i think i prefer that over a button like on the Q20s. Easier to find while wearing if i ever want to turn ANC off.(update) after a few days of using these, they're still my favorites, but ive noticed some background interference when music is off and a noise is played on my phone (alert / notification), as well as during calls. It only happens with ANC is on, so I always turn ANC off when taking or making a call (which is very easy with the ANC switch). It's almost as if the ANC acts as an amplifier...music sounds much better to me when ANC is on, but when the music is quiet you can hear the interference. if there are no sounds playing from my phone (music / call / alert / notification) ANC seems to work as it should with no background interference noise.Battery Life:i havent done any real testing on the battery. i can say i havent charged them yet, put them on right out of the box and my phone read the battery level as 90%. after 10hrs or so of listening theyre down to 70%. and that's with ANC on the whole time. good enough for me! seem to last longer than my Q20s, i feel like i would have had to charge those by now.Conclusion:I bought a couple sets of the H9000s as backups to my Anker Q20s and my wife's SC Venues, but these will now be my go-to favorites and my Q20s will be my backups. If all 3 (H9000, Q20, Venue) were the same price, i would go with these H9000s. no-brainer if under $30.
