Sennheiser BTD 700 Reviews

Waste of $$

This is the second one I've tried, this newer version is no better than the BTD 600. Tried using them on my Macbook Pro, tried using them on my iphone 16 pro. They don't connect, they blink and blink and blink but never establish a connection. Waste of money.

Needed a better connection...

My tv is a bit older and the bluetoooth connection with my accentum plus was a bit-- skiddish? Popping in and out, vis a vis connection, too frequently. Short lasting, but enough to aggravate. This has lessend the frequency 100 fold. Thought I read it would work for other items but that seems a fallacy, for my sammy buds at least. Not your fault. Prompt service as always, in well managed packaging.
