title: SIMOLIO Digital 2.4GHz Dual Wireless TV Headphones with Spare Battery for Hearing Impaired and Seniors, Tone and Balance Control, Personal Sound Amplifier, 100 ft Work Range, No Audio Delay, SM-824D2
text: Product Description What’s the difference between the normal wireless TV headphone and SIMOLIO professional hearing protection and assistance TV headphone? 1.Normal wireless TV headphone: Amplifying all the sounds on the TV, it’s very hard for the seniors to pick up the TV conversations from the magnificent background sound, so they have to constantly increase the decibel levels, which eventually makes their hearing worse and worse. Pairing and sound delay of Bluetooth are annoying. 2.SIMOLIO professional hearing protection and assistance TV headphone: Voice highlighting and noise cancelling tech dynamically reduces the TV background sound, making the TV dialogue stand out, allowing you to easily understand the TV dialogue at a safe volume level. You can customize your sound at a most comfortable volume level, via balance and tone controls plus mono/stereo option. The built-in microphone lets you separately amplify people’s voice nearby. You don't have to take off your headphone to hear what people are talking to you. NO pairing required, NO delay. IMPORTANT! Before purchasing, check audio output of your TV/related audio source first, Digital Optical (Toslink/SPDIF), RCA or 3.5mm AUX audio out port is what we need. When using TV optical audio out, MUST set your TV audio format to PCM. Not for TVs with non-functional audio out ports (test before purchase). When hooking up an external audio device, some TV internal speakers might not work or become muted. This is TV’s feature. Please refer to the related video and product comparison table at this page for details. If you experience any problem when connecting to your TV system. Pls refer to the user instructions or email to support(at)simolio.com, we are confident to get one good solution for you. The under-chin headset weights 2.04 oz, for sensitive ear canals, please check SIMOLIO neckband in-ear headset SM-828D1/SM-828D2, or over-ear wireless TV headphone SM-825D Pro, or wireless TV speaker SM-621D as alternative. Check the comparison table down the description part for more models designed for TV listening. These RF products are not available for pacemaker carrier as well as people with severe hearing loss. The personal sound amplifier function is designed as an additional & unique feature to help hearing impaired people to temporarily hear what people are talking to him when watching TV. Press the MIC button at the rear of the headset to pause the TV sound and turn to “ personal sound amplifier ” mode, it will amplify the sound around, press it again to return to the wireless listening function. Note: It can't be replaced or used as a hearing aid. Spare Battery Included / Convenient Charging with Two Main Charging Slots / Intelligent Power Saving Equipped with a spare battery and an extra battery charging compartment to avoid TV watching being interrupted by the charging process. For protection of transmitter and power saving, the transmitter will go into standby automatically if there is no audio signal for 5 minutes, if there is no audio signal from the transmitter within 5 minutes, the headset will be shut off automatically. If the audio signal returns, the transmitter will be automatically re-start, but your have to restart the headset by switching it off then switching it on by hand. Comfortable, Durable and Flexible The under-chin design headset will put pressure on your ears if you wear it for a long time. For those who have sensitive ear canals, we recommend choosing SM-621D, which is a portable TV speaker. The unit incorporates "memory stainless steel strips" at the headset beams for adjusting to more comfortable wearing angle and shape. Super- soft and body-heat activated memory foam make you feel much more comfortable. BALANCE (left / right) The BALANCE control is specially designed for people with different hearing levels of the left and right ears. They can adjust the balance control as needed to best fit their listening requirements. MONO/STEREO option, TONE (Treble/Normal/Bass) The MONO/STEREO switch is designed for different sound effect requirements. MONO is better for voice clarity, STEREO is better for music enjoyment. The TONE switch is specially designed to deliver improved dialog clarity for people who have different sound frequency sensitiveness. Select Treble to enhance female voice and kids’ voice, select Bass to enhance male voice. Multiple Audio Out Ports Supports Compatible with most TVs on the market, the SIMOLIO SM-824D2 supports Optical, RCA and 3.5 mm / AUX audio outputs. For Optical connection, make sure the audio format of your TV/TV related AV device must be set to “PCM”. For RCA connection, make sure the RCA ports are labeled as ” AUDIO OUT/OUTPUT/AV OUT” . For 3.5mm/AUX connection, it’s better to try it with a wired headphone to see whether it will disable your TV internal speakers. For TVs with only Optical audio out and occupied by a sound bar, you will need to purchase an optical splitter for installation. For TVs with only Coaxial output, you will need to purchase a Digital to Analog Audio Converter for installation. For TVs with only HDMI (ARC) audio out, you will need to purchase an HDMI to RCA converter for installation. For AV receivers with a 6.35mm phone jack at the front, you will need to purchase a 6.35mm to 3.5mm audio adapter for installation. TV Sound Out and Audio Format Setting For TVs that support only single sound out, we don’t recommend to use this SIMOLIO unit to watch tv together with your family. Unless you have a sound bar + splitter. For some TVs, you can play audio through TV internal speakers and an external audio device simultaneously by setting the “Sound Out” to “Internal TV Speaker + Audio Out(Optical)”. For digital optical connection, make sure to set your TV/TV related AV device’s audio format to PCM. Dolby / DTS is not supported. The menus for sound out and audio format setting are not the same from different TV brands. please refer to your TV manual for details. TV & TV Related AV Devices' Volume Setting Sufficient sound output is needed to ensure Simolio working properly. VOL.1 > 40%, VOL.2 > 30%, just for your reference. The bigger the VOL.1 and VOL.2, the better the S/N (Signal-to-Noise) of your Simolio unit. Usually we suggest to fix the VOL.1 to a sufficient level, and adjust VOL.2 to control TV's volume. If the audio output signal is too weak, it will cause the following problems: no sound from the headset the sound of the headset cuts in and out the headset automatically shuts off every few minutes Read more Wired Long Cord Headphones for TV with Tone Adjustment Digital Wireless TV Headset SM-823D Pro Digital Wireless TV Headset SM-824D1 Digital Wireless TV Headphone SM-825D Pro Wireless Headphones for TV Watching with Bypass and Tone Control SM-828D2 Digital Wireless TV Speaker SM-621D Wireless Technology Not Wireless, Wired with Long Cord 2.4GHz 2.4GHz 2.4GHz 2.4GHz 2.4GHz Operating Range -(5.5M Long Cord) 100ft / 30m 100ft / 30m 100ft / 30m 100ft / 30m 100ft / 30m Digital Connection - ✓ ✓ ✓ ✓ ✓ Comfort Better Good Good Better Better Best Playtime Up to 40 hours 5~7 hours Not Limited Not Limited Not Limited Not Limited Spare Battery - - ✓ ✓ ✓ - Charging Base Charging by USB cable ✓ ✓ - ✓ ✓ Support Soundbar Simultaneously - - - - ✓ - Voice Clear Mode Yes (Tone control inside the earphone) Yes (Tone control on the base) Yes (Tone control on the base) Yes (Tone control on the base) Yes (Tone control on the base) Yes (Tone control on the speaker) Model Number SM-905TV SM-823D Pro SM-824D1 SM-825D Pro SM-828D2 SM-621D

Watching TV Together without Disturbing Others! If you and your roommates are on different schedules, then you might need this TV Bluetooth transmitter for your TV. TROND is the pioneer in promoting the concept of aptX Low Latency on Amazon.com. As the first model we introduced to the Amazon marketplace in early 2016, TROND BT-DUO has helped numerous customers to watch TV wirelessly without any noticeable audio delay. In recent years, we've upgraded its Bluetooth version from 4.1 to 5.0, which could provide better device compatibility. TX Mode: as a transmitter, BT-DUO should be connected to the audio OUT port of your non-Bluetooth audio source (TV, iPod, Nintendo Switch, CD-player, or e-Book reader), and then pair to your Bluetooth headphones or speakers such as Airpods. This way, you could watch videos, enjoy music or play games wirelessly without experiencing lip-sync issues. White/red RCA does NOT support Audio IN, only Audio OUT. If your TV does not have an audio out port please order another model: TROND BT-DUO X. RX Mode: as a receiver, it should be connected to the audio IN port of your wired audio device via a 3.5mm cable (wired earbuds, speaker, or car stereo), and pair to your Bluetooth-enabled smartphone, tablet, or laptop. This way, you could enjoy high-quality music wirelessly without spending more to order Bluetooth headphones or speakers. Please note that you can only use BT-DUO either as a transmitter or as a receiver and can't use those two modes simultaneously. Also for the Bluetooth technology, one transmitting device needs to pair with one receiving device, or vice versa. You are not supposed to pair two transmitting devices or two receiving devices together Important Pairing Instructions How to Pair with One? Disconnect your headphones from your phone or tablet; Switch the working mode to TX, instead of RX; Long press the MFB for 3 seconds to power it on; Quickly double-tap the MFB to activate its pairing mode till the indicator blinks red & blue alternately; Activate the pairing mode of your headphones; (To activate Airpods' pairing mode, put the Airpods (Pro) in the charging case; long-press the button on the back of the charging case, and then released it when the white light on the front started flashing) Put those two close to each other, and wait for the pairing; if successful, its LED would turn solid blue. How to Pair with Two? Dual Stream is the embedded feature of CSR 8670 chipset, which allows the transmitter to pair with two devices simultaneously. Please CLOSELY follow the instruction included in the user manual to pair with two. However, the pairing steps may be too complicated for some customers to pair. Getting audio out of one headphone? BT-DUO is capable of working and charging at the same time. But rarely, you may only get audio in one earpiece when the BT-DUO works while charging. Please charge BT-DUO first, then unplug it, and then use it, so you get sound on both sides.

Read more Important Remarks before Buying: 3.5mm Aux or Digital Optical? In order to stream the audio from your TV, it’s very crucial to first identify which audio OUT port your TV could support (instead of any audio IN or video port). TROND BT-DUO can be connected via the 3.5mm cable. However, some LG or Samsung TVs have removed the 3.5mm aux jack and only offer the digital optical OUT port. In this case, since BT-DUO does not feature a port for digital optical cable, please order a digital to analog audio converter additionally, or order another model instead: TROND BT-DUO X; AptX Low Latency Supported? In order to avoid lip-sync issues, your BT headset or speaker also needs to support the codec of aptX Low Latency. Please check with your device manufacturer to verify this. If not, the codec would be downgraded to aptX or even SBC, and you may experience the noticeable audio lag; Musical Instrument? The latency of 40ms is still unacceptable for live sound monitoring. Therefore, those who plan to use it with electric piano or guitar, beware! Bluetooth technology, even with aptX Low Latency, may not suit your needs; Pair with your car Bluetooth (TX)? Car Bluetooth may require entering a certain pin code in order to pair with your phone. Unlike phones, Bluetooth transmitters don't have any keypad to enter the pin code. Therefore, BT-DUO may not be able to stream the music from your iPod to your car stereo. Due to the rechargeable battery design, it cannot be powered on automatically after you start the car engine; Bluetooth Receiver for Car? YES, some cars only have aux jack and have no Bluetooth function, you can use TROND BT-DUO as a Bluetooth receiver, this way, it will allow your car to have Bluetooth functions. Simply pair the Bluetooth receiver with your iPhone 11/pro and start to enjoy stereo music wirelessly. Please note the Bluetooth receiver will automatically power off if no device is paired within 6 minutes in the standby mode or the pairing mode; Hands-Free Phone Calls? BT-DUO doesn't have the built-in microphone. If connected to BT-DUO as a receiver, the in-line microphone of your wired headset will be disabled. Therefore it won't be able to support any phone calls. Sound cut out at lower volumes? When watching movies at lower volumes(also known as a gate), the transmitter sound may cuts out. Because when the volume is too low, the CSR chipset couldn't detect the signal and hence couldn't transmit the audio signal out. Please try to turn the TV's volume up and get better performance. White/Red RCA support audio in or audio out? In TX mode, white/red RCA does NOT support Audio IN, only Audio OUT. If your TV does not have an audio out port please order another model: TROND BT-DUO X.

Can I make them work simultaneously while using the transmitter? A: This is a TV feature and its availability depends on your TV make and model. For many models of TV, the built-in speakers might not work if you choose to use an external speaker. They will either automatically mute when you plug something into an audio output port (AUX, RCA, Optical, etc.) or they become disabled once you choose "External Speakers" as your TV's audio output. Some newer TVs however, allow you to play audio from both the TV's internal speakers and an external audio device simultaneously. For example the newer LG TVs with WebOS versions 3.0 and 3.5 have this feature but Samsung TVs still do not. In the LG TV WebOS 3.0 / 3.5 example, you can enable this feature by changing the TV AUDIO OUT setting from "Internal TV Speaker" to “Internal TV Speaker + Optical”. Now all audio will simultaneously come from both your TV's speakers and the device connected to the digital optical audio output port. If your TV does not support this feature, then you can consider the Avantree HT5009 / HT5006 and an external speaker. The Avantree Oasis Plus transmitter has a convenient bypass feature which allows you to share the TV audio simultaneously with an EXTERNAL SPEAKER and a pair of Bluetooth headphones.
