It's another week and another round of excellent Android accessories. Every Sunday, we try to find great products that have been released recently and play nice with your Android phone or tablet. These include fitness trackers, speakers, and some more basic (but admittedly useful) gadgets. Without further ado, let's dig in.

READ NOW: The best new Android gadgets of the week!

1. Microsoft Foldable Keyboard

Microsoft recently announced a swanky new foldable keyboard that works with just about every platform. The Foldable Keyboard has three months of battery life on a single charge, and manages to maintain a slim 5 mm profile. It's spill resistant, which is nice to have if you're working from the coffee shop, and the ability to pair up with two devices means you can work on both phone and tablet over Bluetooth 4.0. Check out Windows Central's full review for all the details.

2. MOOV Now

Preorders for the next generation MOOV fitness tracker just opened up. MOOV set itself apart by being a sports-oriented fitness coach, rather than a passive monitor. This means detecting your strides when running or strokes when swimming, and offering tips as you go. You can use more than one of these to provide a ton of data to the mobile app, no matter your fitness regimen. The latest model is smaller and lighter than the original, and switches to a replaceable watch battery for power, which should last for 6 months of usage. Currently, MOOV Now is available at an early bird price; expect it to go up to $100 once it hits retail this fall.

3. SanDisk Connect Wireless Stick

SanDisk announced a surprisingly helpful new flash drive built for talking directly to your phone, tablet, and computer. The SanDisk Connect Wireless Stick is available in denominations ranging from 16 GB to 128 GB, and can store files from your device thanks to dedicated iOS and Android apps. Whether it's video or music, it's all wirelessly accessible. You can even stream media out to three devices at once, provided the Connect Wireless Stick has a charge.

4. Chromecast Ethernet Adapter

Google released a simple but handy accessory for Chromecast that allows you to plug the TV-streaming stick directly into an internet hardline. The ethernet adapter also provides power to your Chromecast with minimal fuss. If you're the type to watch a lot of your home content over Chromecast, this simple upgrade could make your buffering times just a little zippier.

5. Polar Loop 2

The Polar Loop 2 is another fitness tracker to make its debut this week. Like the previous generation, it keeps tabs on your day-long activity level and sleep. A dot matrix LED continues to provide at-a-glance information. New to the mix are phone notifications and vibration alerts, though you'll still need one of Polar's other accessories for heart rate monitoring. A companion app lets you see if you're meeting fitness goals throughout the day. iMore's review of the last version showed that the Loop was quite comfortable to wear and well-built.
