Review: Nice When you can Just Love Something - Does exact what it promised. Augments sound from TV and SURROUNDINGs (at the touch of a button). Works perfectly with Samsung hospitality model TV. I can set the TV to any volume and Simolia works independently via the optical port. My mother did seem to prefer the sound via TV Ears digital more but one charge port broke quickly on the dual transmitter base, came with no extras doesn't work but 3 ft from the transmitter and dies after 2 to 3 hours. This Simolio comes with extra ear tips- 2 types. Washable silicone and disposable foam. It has the extra battery and needs no screw driver to open the batt cover. Interestingly it also has ear loops for those who want the device to hang from the top of your ear, up where one's eyeglasses sit. Manual is well written and almost too detailed. Sooo many ways to attach it. It's simply an A+ item. 1 nagging Neg Green Light flashes on the base after you've cut the TV off. It does that wherever the port isn't transmitting sound. So if it's in your bedroom and you hate light there like we do, be sure to cut the set off more than 10 minutes before you try to sleep to give that light time to become steady. Then cover it with something. I keep asking manufacturers to put a DARK SLEEP MODE on all electronics. Still isn't happening enough.
Review: Happy with purchase - Great... sound is terrific

## Questions & Answers

**Q: Will these headphones work with my smart Samsung TV?**
A: Yes, these wireless TV headphones work with LG, Samsung, SONY, VIZIO, Panasonic, TCL, Roku, Hisense, Sharp, Toshiba, Sanyo and nearly ALL TVs on the market. Pls check if there is Digital Optical Audio Out, RCA or a headphone out port on your TV.

**Q: When using these TV headphones, will it turn off the sound coming from the TV speakers?**
A: It actually depends on your TV's settings. For most smart TV models, they have option to play audio from both the TV's internal speakers and an external audio device simultaneously.

**Q: Why there is no sound under optical connection?**
A: What you are experiencing is an incorrect audio format in Netflix and/or your TV. Pls check your Netflix app audio options. If surround sound (5.1) is selected, try changing it to Stereo (PCM). Additionally, please update TV's audio settings to PCM.

**Q: Will these headphones work with my current 2.4GHz wireless TV headphones?**
A: It depends on your purchasing date and the product model of your previous purchase. Please write to us for confirmation. Response time is 2-6 hours!

**Q: Can I use two of these headsets on two different TVs in the same house?**
A: Yes, but only when the distance in between is at least 10 meters. If two headphones need to be used in close proximity, SIMOLIO JH-737D is recommended.

Great... sound is terrific

### ⭐⭐⭐⭐⭐ Simolio dual wireless headphones.
*by E***E on November 6, 2025*

I purchased these headphones on November 23, 2024. One of the headphones stopped working about September 15, 2025 and the other one stopped working about October 1, 2025. One year warranty was still in effect. I contacted Simolio on October 25, 2024. After trying several of their suggestions, it was determined the problem was the headphones. Simolio sent replacement headphones which were received November 6, 2025. The replacement headphones are working good. Thank you, Simolio for resolving the issue in such a courteous and timely manner. Elaine Hinkle
