Setup
1. Powering the Transmitter Base
- Connect the USB charging cable to the POWER DC 5V port on the transmitter base.
- Plug the other end of the USB cable into the provided power adapter.
- Plug the power adapter into a wall outlet.
2. Connecting to Your TV/Audio Source
The SM-828D1 supports Optical, RCA, and 3.5mm AUX audio outputs. Choose the appropriate cable based on your TV's available ports. Only one audio cable connection is needed.
- Optical Connection: Use the Optical Audio Cable. Connect one end to your TV's 'Optical Out' port and the other end to the 'OPTICAL IN' port on the transmitter base. Important: When using the TV's optical audio output, you MUST set your TV's audio format to PCM. Refer to your TV's settings menu for this adjustment.
- RCA Connection: Use the RCA Audio Cable. Connect the red and white plugs to your TV's 'Audio OUT' RCA jacks (usually labeled R and L) and the 3.5mm end to the 'AUX IN' port on the transmitter base.
- 3.5mm AUX Connection: Use the 3.5mm AUX Audio Cable. Connect one end to your TV's 'AUX Out' or headphone jack and the other end to the 'AUX IN' port on the transmitter base.
This chart indicates which TV audio output jacks are compatible with the SM-828D1 headphones, including Optical, RCA, and AUX 3.5mm. It also notes that for Digital Optical connection, the TV audio format must be set to PCM.

3. Charging the Headphones and Spare Battery
The headphones and the spare battery can be charged using the 3-in-1 transmitter base.
- Headphones: Place the headphones onto the magnetic charging slots on the top of the stand. Ensure the charging contacts align.
- Spare Battery: Insert the spare Li-ion battery into the dedicated charging slot located on the base.
A full charge typically takes approximately 3 hours and provides up to 7 hours of playtime. The spare battery ensures continuous listening by allowing you to swap batteries when one runs low.
Operation
1. Wearing the Headphones
The SM-828D1 features an ergonomic neckband design and comes with various sizes of silicone and memory foam ear tips. Choose the ear tips that provide the most comfortable and secure fit for optimal sound quality.

2. Powering On/Off
- Transmitter Base: Use the ON/OFF switch on the base to power it on or off.
- Headphones: The headphones automatically power on when removed from the charging base and power off when placed back on the base or after a period of inactivity.
3. Adjusting Sound Settings
- Volume Control: Use the '+ VOL -' slider on the headphones to adjust the listening volume to your preference.
- Balance Control: Use the 'L BAL R' slider on the headphones to adjust the audio balance between the left and right ears. This is useful for individuals with different hearing levels in each ear.
- Tone Control: Use the 'TONE' switch on the transmitter base to select between Treble, Normal, or Bass settings. This allows you to customize the audio frequency response for clearer dialogue or richer sound.
- Stereo/Mono Mode: Use the 'STEREO / MONO / OFF' switch on the transmitter base to select between Stereo for Hi-fi music or Mono for clearer TV conversations.
4. Using the By-Pass Feature
The innovative 'By-Pass' feature allows simultaneous audio transmission to both the wireless headphones and a wired soundbar or AV receiver. This is ideal if your TV has only one audio output and you wish for others to listen via external speakers while you use the headphones.
- Connect your TV's audio output to the 'OPTICAL IN' or 'AUX IN' of the transmitter base.
- Connect your soundbar or AV receiver to the 'OPTICAL OUT' or 'AUX OUT' of the transmitter base.
This diagram shows how the by-pass feature allows audio from the TV to be transmitted to both the wireless headphones and a wired soundbar simultaneously, eliminating the need for an external splitter.
5. Multiple Headsets Support
One SIMOLIO SM-828D1 transmitter base can transmit audio signals to multiple SM-828D1 headsets simultaneously. This allows several individuals to listen to the same TV program using their own headphones.
This illustration demonstrates that a single SIMOLIO transmitter can broadcast audio signals to several wireless headsets simultaneously, allowing multiple users to listen to the TV.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the headphones and transmitter base. Avoid using harsh chemicals or abrasive materials.

Troubleshooting
- No Sound:

- Poor Sound Quality/Static:
- Ensure the headphones are within the operating range (up to 100ft/30M) of the transmitter.
- Check for potential interference from other 2.4GHz devices.
- Adjust the 'TONE' switch on the transmitter base.
