Audio-Technica's Solid Bass ATH-WS990BT headphones do a great job and mind your safety

ATH-WS990BT is the flagship model of Audio-Technica’s Solid Bass series that feature Bluetooth connection, noise cancelling and High-Resolution Audio when used with a provided cable.
It can also be used as smartphone headset with built-in microphone and control buttons.
The ATH-WS990BT wireless over-ear headphones combine exclusive 53mm Deep Motion Drivers with large, high-flux magnetic circuitry and Bluetooth technology to deliver vibrant full-range wireless audio with invigorating bass. The drivers have frequency response of five to 40,000Hz, so the WS990BT supports Hi-Res Audio when used with the provided 1.2-metre headphone cable. 
When connected in Bluetooth, it doesn’t provide Hi-Res Audio quality because the the Bluetooth protocol used does not provide enough bandwidth for the high sampling rate of Hi-Res Audio.

The headphones have high sensitivity of 101dB when the noise-cancelling function is not turned on. When the noise-cancelling function is turned on, the headphones have high sensitivity of 107dB. The WS990BT has impedance of 30 ohms when not using noise-cancelling and 150 ohms when using noise-cancelling.
Audio-Technica says the headphones’ powerful magnetic force of the circuitry results in dynamic, well-tailored diaphragm response to reproduce deep, clear low frequencies and detailed mid-to-high frequencies. 
The sound is further enhanced by the exclusive dual-layer, memory-foam earpads, comprised of a firm internal layer and a soft outer layer, that provide excellent sound isolation and comfort. 
The WS990BT uses built-in lithium polymer rechargeable battery that takes about five hours to charge from 0 to 100 per cent. The headphones last about 25 hours when using Bluetooth and noise-cancelling. When using only Bluetooth and turning off noise-cancelling, the battery can last for about 30 hours.
The battery can last up ot 35 hours when using noise-cancelling only. This is because when you use the headphones with a headphone cable, the Bluetooth will automatically turn off, while you can still turn on the noise cancelling to enjoy Hi-Res Audio music in quiet environment.
The noise-cancelling function turns on automatically when you turn on the headphones with the power switch. When the noise-cancelling function turns on, the built-in microphones pick up the noise around you, and the headphones will produce signals to cancel and reduce the noise.

I found during the test that the headphones reduced the humming sound of my air-conditioner and provided a quiet listening environment for me to enjoy the music.
Anyway, you can turn off the noise-cancelling function by double-tapping the touch sensor on the right ear cup. When the noise-cancelling function is turned on, a lamp indicator turns green. The lamps turn off when the noise-cancelling function is also turned off.
Apart from the noise-cancelling function, you can select the hear-through function that allows voices in the surrounding area to be heard through the headphones. This lets you listen for important announcements, say in a train station or airport, and hear the voice of anyone who might engage you in conversation. 
When you use the headphones on the road, it can be dangerous if you don't hear the sounds around you, such as the sounds of vehicles coming up behind you.
The hear-through mode can help you be aware of what’s happening around you. You can turn on the hear-through mode by pressing and holding the touch sensor for about two seconds. When the hear-through mode is turned on, the touch sensor indicator lamp will flash green. And in the hear-through mode, the volume is automatically lowered to assimilate to the sounds around you.
You can turn off the hear-through mode and return to noise-cancelling mode by pressing and holding the touch sensor for about two seconds and the touch sensor indicator lamp will turn solid green.
There is a jog switch next to the touch sensor. When the WS990BT is Bluetooth-linked to your smartphone, you can use the jog switch to control music playback and volume and to answer and end phone calls.
You can slide the jog toward the plus sign on the front to increase volume by one level or you can slide and hold the jog by two seconds to skip the next track. Or you can slide the jog toward the minus sign or to the back of your head to decrease the volume by one level. You can slide and hold the jog back for about two seconds to play the previous track.
When the WS990BT is connected with Bluetooth to your smartphone, you can press the jog switch once to answer an incoming call and during the call, you press it once to end the call.

When there is an incoming call, press and hold the jog switch for about two seconds to reject it. When on a call, press and hold for two seconds to switch to the phone.
During the test, I found that headphones reproduced good quality music on a Bluetooth connection, using aptX connection protocol.
But the music quality was much improved using the cable with the noise-cancelling function still on. I tested playing Hi-Res Audio songs in FLAC 24bit/192kHz format from my Sony XZ Premium and the music quality was great with good details and powerful and solid bass.
ATH-WS990BT is distributed by RTB Technology and it is available at Studio7 shops and IStudio, dot.life, Siam Discovery, Jaymart, Munkong Gadget, Betrend, Power Mall and Lazada for Bt9,900.
