I purchase almost exclusively Anker. When my cheap Bluetooth headphones had a hard time connecting to my phone they just sent me a more expensive pair. I have their cords, wall charger, battery pack, headphones, outdoor speaker, and indoor speaker. All work well and when they stopped or seemed to function inadequately they just sent a new or updated version. I can't recommend them enough.
