Sennheiser BT600

This is to replace an existing BTD800. Connection was greatly improved in terms of range and quality and no longer experiencing choppy or paused audio during audio streaming on conference call and media playback.

Almost perfect BT Dongle/Transmittor

I own a M3 headphones, despite it does not support the latest codec APTX Adaptive, with the HD and APTX, it already blow the built-in BT from the smart phones and laptop off the chart. With the same device (Smart phone or Laptop), the range to the same headphones (M3), gets so much further then befoe. Pairing to another device, is so much simple, just hold the button for 3 sec, put your headphone into pairing mode, and thats it. You can get another SG brand BT dongle but, higher pricetag and does the same thing but, a bit bigger in size. Its future proof as its BT V5.2. Get the BT600for Good for it if you want the seamless connectivity.

BTD 600

Was using iPhone which only support AAC format. I own a Momentum True Wireless 3 earbud and this allow me to play aptx adaptive codec using my iPhone.
