Dual NuTube 6P1 Tubes:-

Developed by KORG and Noritake, the 6th gen NuTube on the iBasso PB5 operates exactly as a conventional triode vacuum tube and creates the same rich and dynamic overtones that are appreciated in a desktop tube amplifier. NuTube achieves substantial power savings with a high-efficiency design. Voltage amplification is also achieved with the NuTube, which results in a captivating and distinctive vacuum tube sound.

iBasso PB5 adopts a high-efficiency power circuit. The amplifier utilizes six batteries for a robust power supply system.

Super comfy, but side strap is a bit annoying
Size: 9, Color: Black Leather
Honest review of these shoes that I just wore to a wedding. They are SO comfortable, I wore them all night and didn't need to take them off. The only issue is that since the one strap just goes along the one side of the top of your foot, I did feel like it kind of pushed the shoe to the side. It's hard to describe, but when I was walking sometimes I could feel my food shifting off my shoe on the side.

Comfy shoe, Not a great dupe
Size: 6.5, Color: Black Leather, Size: 6.5, Color: Black Leather
These are so cute and comfy and I love them. Minus two stars because I specifically bought them for the little silver SM on the bottom so they’d look better than the ones at Walmart. These did not come with the little silver logo on the bottom.

Super cute but came damaged & really annoying to walk in
Size: 8, Color: Black Leather, Size: 8, Color: Black Leather
Super cute but mine came damaged and the straps don’t stay up great… I love Steve Madden shoes, and own a few pairs already, so I had high hopes for these heels. I ordered these for a wedding coming up and I hadn’t opened the package right away as I was out of town, when I got back I was so excited to try them on only to find that they came already scuffed on the toes and heels!! It looked like they had been worn multiple times already, so that was upsetting. In terms of fit, I ordered a size 8, and it fit true to size as far at the sole goes, as for the strap that goes from in between your toes and around your heel, it falls off after taking 3 steps and is honestly really annoying! The strap that goes across the top of your foot was also wayyy loose on my feet and didn’t help the other strap stay in place much making it super difficult to walk in them, every step felt like they were about to fly off my feet! Unfortunately, I will be returning them.
