Xvive Audio T9 In-Ear Monitors

Featuring dual balanced-armature drivers, the T9 In-Ear Monitors from Xvive are designed to deliver an audio performance rivaling a customized set of earphones, but at a much more attractive price point for musicians and music lovers. The unified crossover has been engineered to ensure that each driver is only sent the frequencies it is capable of accurately reproducing. The low-frequency driver provides powerful mid/bass down to 20 Hz, while the custom-tuned, custom-ported micro tweeter supplies high frequencies up to 16.5 kHz, almost the full range human ears are capable of hearing.

The T9 delivers a clear, natural, and unhyped sound that ensures musicans can trust their mixes and recordings. Audiophiles will appreciate the headroom to accommodate customized EQ settings from source material, letting you boost the bass or dial in more high end without having to worry about distortion. The detachable 3.9' cable connects to a wide range of audio gear and mobile devices via a common 3.5mm TRS connector; a 1/4" adapter is also provided.

Features
  • Sound-isolating earphones
  • Dual balanced-armature drivers
  • Hand-assembled
  • 3.5mm earphone jack, compatible with all systems
  • Carrying case and cleaning tool included
  • Durable, replaceable cables
  • Custom-designed unified crossover ensures that the drivers are sent only frequencies they are designed to reproduce
  • Pairs perfectly with U4 wireless in-ear monitor system (available separately) for hands-free monitoring for stage and studio applications

Very nice pillowcases
Color: 06 - Beige, Size: Standard (20" X 26")
These pillowcases are really nice. They're soft and wash well. I really like the pocket on the end. It makes your pillows look nice and neat. The price is good too.

Love the sheets but GOSH THEY STINK
Color: 19 - Forest Green, Size: Queen (20" X 30")
I have the dark green sheets and bought these for extra cases to match. I would give them 5 stars if it weren’t for the fact that they smell absolutely horrible. I am so surprised after reading reviews that more people don’t mention it?! Maybe it’s more prominent in darker colors but I have washed these now 3 different times even with scent beads and still hate the smell. I wish I could accurately describe what it smells like— it’s just not good and for some reason, body heat only exacerbates it and makes the smell even worse and I wake up feeling like a smell like the sheets… which isn’t a good thing. Besides that, I do really enjoy them. They feel great on your skin and I love the color. I wish the smell didn’t kill them so badly for me ☹️

Comfy soft pillow covers
Color: 02 - White, Size: Queen (20" X 30"), Color: 02 - White, Size: Queen (20" X 30")
Absolutely love these pillow cases! I bought 2 sets. After I received them & washed & dried them they did remain wrinkly. I just went ahead and put them on my pillows & the wrinkles went away. I continue to love the feel, coolness & comfort. Will definitely buy more.

These Bamboo Pillowcases Made Me Realize I Sleep Hot
Color: 07 - Cream, Size: Queen (20" X 30"), Color: 07 - Cream, Size: Queen (20" X 30")
I bought these mostly because I kept hearing people talk about bamboo pillowcases and honestly thought it sounded a little overhyped, but I totally get it now. The first thing I noticed was how cool they felt compared to regular cotton. I tend to get warm when I sleep and flip my pillow a million times during the night looking for the cold side, and these actually stay noticeably cooler longer. They also feel really soft without having that weird slippery texture some silky pillowcases have. My skin has been less irritated lately and my hair definitely looks less frizzy in the mornings. I have thick hair that tangles easily overnight, and these have helped more than I expected. Another thing I appreciate is that they’ve washed well so far. I was worried they’d pill or lose softness after a wash cycle, but they still feel smooth and nice. They also just make the bed feel cleaner and more comfortable overall. One of those small upgrades that ends up making a bigger difference than you’d think.
