    Seller took proactive steps to resolve shipping debacle. It was circling around and around. After finally receiving package, cannot find any reasons for this delay other than the USPS incompetence. The tube is described as advertised and communication was superior throughout this ordeal.

NEW NIB HyperSonic Sound HSS-H450-B Long-Distance Ultrasonic Directional Speaker
May 02, 2016
HSS-H450-B SPEAKER
THESE ARE RATHER LOW QUALITY SPEAKERS DESIGNED IN THE FIRST YEARS OF THIS TECHNOLOGY. WHEN I CONNECTED MY I PHONE TO IT AS A MUSIC PLAYER THE VOLUME SOUNDED DISTORTED AND WAS CLIPPING THE RED OVERLOAD METER LIGHT BY THE TIME YOU GOT TO A QUARTER TURN. THE VOLUME OUTPUT IS RATED AT 85 dB! , THAT IS PRETTY LOW FOR A SPEAKER THAT HAS A BUILT IN AMPLIFIER, IT DOES NOT HAVE PROVISION FOR AN EXTERNAL AMPLIFIER LIKE SOME CLAIM IT DOES AND ONLY HAS A PAIR OF RCA'S FOR LINE LEVEL INPUT. ITS A NOVELTY ITEM THAT WILL COLLECT DUST IN YOU CLOSET AFTER THE FIRST TIME YOU USE IT.
Rupert Neve Designs RNHP Headphone Amplifier
Mar 11, 2024
A compromize compared to other cheaper amps
Noise spectrum is clean. SINAD which is the sum of distortion and noise comes in at 101 dB which is caused by 2nd harmonic. This kind of performance would have been very good a few years ago. But now? It is well below a dozen or more amplifiers: Unlike a lot of boutique audio products, the RNHP is not particularly broken. With 300 ohm load it actually sounds find and provides good objective performance. Low impedance headphones that are inefficient though give it a very hard time causing its performance to fall apart. At this price point, there is no excuse for this. If you have it, and are using a high impedance headphone with it that is getting loud enough, then it is fine to keep it. But I would not purchase one new given half a dozen superb sounding and performing headphone amplifiers with more features and lower prices. Needless to say, I can't recommend the RNHP.

THIS TAPE ISNT FOR AUDIO AT ALL, ITS STRICTLY FOR DATA LOGGING COMPUTERS FROM DECADES AGO. DONT BE FOOLED WITH WORDING. THIS WILL NOT WORK ON YOUR AUDIO REEL TO REEL RECORDER.
