In newer SoCs data packets are processed as follows. Because of it in our PoC we use Arduino and MAX3421E to control early initialization of USB. SET_ADDRESS, see this for more info) sent by OS before we can work with device. This algorithm is fully described here by littlelailo.īut, if we use any normal OS with default USB stack for exploitation, then we can't avoid standard device requests (e.g. So, to be able to write to the freed io_buffer, we do steps 1-4, then send an incomplete HOST2DEVICE control transaction to set global state, then trigger bus reset.

ctrlReq(bmRequestType = 0x21,bRequest = 1,wLength = 0x40) with any data.

Because of this we can't use ctrlReq(0x21,4,0) to reenter DFU. So, if we send any HOST2DEVICE control request without data phase, then ep0_data_phase_length will be reset to zero. wIndex) = 0, then data phase length will be touched anywayĮp0_data_phase_length = request_handler_ret || (request_handler = *( int (_fastcall **)(setup_req *, _DWORD *))(ep_array[ LOBYTE(g_setup_packet.

With that said, the TWS-X9 wireless earphones batteries have a working voltage of 3.7V which seems to deliver enough power to the speaker drivers so the sound isnt tinny. Most earbuds tend to be set below 16 ohms since the higher the impedance rating the more power is required hence a headphone amplifier dac is needed. The sound is good with clear highs, a touch of bass and loud volume even though they are rated at 32 ohms which is unusually a very high impedance rating for earbuds of this size.

Once paired, you also wont need to pair a second time as the earbud will re-connect with your phone automatically when you turn them on and Bluetooth is turned on your phone. Pairing procedure is simple and only requires pairing one earbud to your smartphone because both earbuds are already paired to each other from factory.

The TWS-X9 are wireless earbuds with Bluetooth 4.2 connectivity so you get a more stable bluetooth signal range (10 meters in direct line of sight). You can also activate your phones smart assistant by tapping either button three times. The led glows constantly during use and there is no option to turn the led off.Īside from volume control, you can play pause (single tap), skip to next song (double tap), answer and reject calls by single tapping either button during an incoming call. Speaking of calls, when answering a call audio is only heard on the right earbud which is by design (all true wireless earbuds deliver audio to one single earbud). The TWS-X9 have a high gloss black finish with a single touch sensitive button on each earphone and a built-in microphone with CVC 6.0 noise cancellation which drowns background noise during a phone call.

The charger case has built-in to it a 400mAh rechargeable battery that can power the earphones for an extra 16 hours as the earphones built-in battery can power them for 3.5 hours on high volume from a single 1 hour charge.Īfter full charge is complete, the charger case stops charging the earbuds automatically, which is good to know since constant charging does decrease a batterys life expectancy. There are four led indicators to let you know the amount of charge being held. The TWS-X9 charger case can fully recharge the earphones four times over and takes just 4 hours to fully charge. The earbuds are held in place with magnets so they wont fall out from the charging cradle. The top section of the box is magnetized so it soft-closes staying shut securely.

The earbuds slide out halfway because of a built-in bumper stop that prevents the earbuds sliding out fully. The TWS-X9 charger case has a similar design to a kitchen cabinet draw so the earbuds slide out when you pull the top section apart.
