Testing & Performance

FENDA Paragon HW620 Bluetooth Wireless Headphones

To test the F&D Paragon HW620 I used the testing suite at Audio.net. It’s a great site with a plethora of tools for testing all types of audio products. You can also download their test files to your media device and test on the go when your shopping. Testing before you purchase saves a lot of time and assists in finding the right product the first time.

Frequency Response

The first test was to evaluate the bass extension, in which a good set of headphones should go as low as 20Hz, and the second was to explore the treble extension, to reproduce frequencies up to 20Khz, the upper limit of our hearing. The F&D Paragon HW620 had excellent frequency reproduction.

Dynamic Range

Dynamic range is the ratio between the quietest and loudest signals that we can hear. It’s important to know that this test is not related to a specification, but will allow you to test isolation within a noisy environment. Noise cancelling headphones or earbuds naturally provide more isolation due to their construction. The F&D Paragon HW620 did well on this measurement as also.

Quality

We scanned the bass frequencies to define how tight the speakers were. If they are old or poorly made they would emit a rattling or buzzing noise. Again the headset performed well and the sound reproduction was clear and firm without any poor quality noises.

Driver Matching

To establish a full stereo image, the two speakers are required to have tight tolerances within their frequency responses. This will confirm the pair are matched. It’s preferable to close your eyes and listen, which should sound centered in your head. The pair I used were very well matched.

Wiring

If the headset is wired properly, the left channel should be heard on the left and the right channel on the right. This also preserves polarity. The Paragon HW620 I used had the correct polarity and performed as expected.

Binaural Test

I found this test very interesting. In essence it is a recording of someone knocking on two different doors in two different ears. The intent is to define how realistic the sounds were. I would when playing the file I would naturally turn in that direction to see who was knocking. The sounds were very believable and naturally reproduced.
