The connectivity type of the headphones.
Bluetooth is a wireless technology standard that allows data transfers between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves. Newer versions provide faster data transfers.
aptx Adaptive is an audio codec for Bluetooth devices that is developed by Qualcomm. It has a variable bit rate (between 279kbps and 420kbps), which means it can adjust the bit rate for different scenarios, such as listening to HD audio or reducing interference from other devices.
aptX is a codec used for transmitting audio wirelessly with Bluetooth. It is developed by Qualcomm, and supports 16-bit audio at a bit rate of 384kbps.
LDAC is a codec developed by Sony for Bluetooth audio. It is capable of a very high bitrate of 990kbps, which provides high resolution audio. It can also automatically adjust to a lower bitrate of 330kbps or 660kbps to increase stability.
aptX Low Latency is a codec developed by Qualcomm. It uses Bluetooth 5.0 technology to provide low latency audio (around 40ms), which is useful when you want to avoid audio lag (e.g. when playing games).
aptX HD is an audio codec for Bluetooth devices that is developed by Qualcomm. It supports high quality 24-bit audio (at a bit rate of 576kbps).
aptX Lossless is an audio codec for Bluetooth devices that is developed by Qualcomm. It supports high quality 16-bit/44.1kHz audio (at a maximum bit rate of 1200kbps). This codec provides CD-quality audio without any loss of data.
AAC is a codec that is used for Bluetooth audio. It supports 24-bit audio at 250kbps. Because it uses psychoacoustic modeling, it can provide better results than other codecs at a similar bit rate.

I owns both headphones. MY MDR7506 is a used one, YR 1991, 30 years old and still going strong. MDR7506 is a lot better soundwise. The bass is more powerful and cleaner. MDR7506 shines when it comes to treble. It does not have noise cancellation but I am ok with it. There are a few good points with WHH910N. It is wireless, tactile, lighter and lasts very long on one full charge. I use the WHH910N mainly for watching TV, but as far as music is concerned, I would prefer MDR7506 especially when I am working on the laptop / Desktop. My opinion is that the MDR7506 is the winner when it comes to sound.

After nearly eight years

I have been using them for nearly eight years, I have changed three pairs of earpads (the last ones perforated and expensive, but fabulous for comfort). Great listening headphones to not faint. When I bought them, discounted by 50%, they were on offer, but their full price was still around € 130-150. They are not completely neutral. A little lacking in the deep bass and excessive in some high frequencies. You can noticeably improve with an equalizer, even software. On pc I use APO equalizer for Windows & PEACE. They have always been comfortable. For listening to movies and series, they are excellent, for music, as mentioned, they must be equalized correctly. They are born as a studio monitor, but I don't know how realistic the pro use is. In any case I feel very comfortable, they are quite comfortable both on the head and on the ears. I changed the first pavilions after about three years of very frequent use: 2-4 hours almost every day. Always the first pavilions are decently insulating, but the outside does not disappear and something comes out. They are very popular and still today they are good headphones, completely repairable, a sign of the pro address.
