JBL T501 BT and comapring with the T500 model

First before reading the story please oblige yourself to send your comments below. The writer  needs to know  your opinions .This will be a serious reason to  terminate this free service  

 ----------------

The model was purchased with the aim of using a BT model in the city shack where I conduct most of my audio work, including Dxing, cross-testing audio equipment, and experimenting with antennas and wires to achieve the clearest possible radio reception in town, particularly for shortwaves and LMF. Additionally, it involves printing Dx and other related internet material at the lowest possible cost compared to the roughly double cost in the village.

This Bluetooth model is used mostly to remotely adjust the loop antennas for the lowest noise. The author mentions using it to remotely listen into shortwaves etc while assisting his elderly mother. Additionally, this Bluetooth model is used in part to remotely adjust the loop antennas for the lowest noise.

 

The BT500 and T501 have an identical design, with the only difference that the T500 is cabled while the other model includes a USB C socket for charging and a control panel . Unlike the other tested models, this model utilizes a separate button to initiate or terminate Bluetooth connectivity. When connected to either a PC or smartphone, it is identified as 'JBL Tune 510 BT'.

 

 

After conducting a sound comparison between the T500 and the newer 501BT, it was found that the sound level of the T500 is 14 steps higher when set to level 50. This equates to roughly a 10db difference. However, the T500 has higher bass while the 501BT has lower bass and slightly higher treble, resulting in a more 'linear' sound.  

When testing the audio quality between a smartphone and a laptop on the same channel, the sound is nearly identical.

Hope later to conduct the final test by using a tone generator file fo better crosstesting between both models
