Sonic AlertCL7350 Opti Wireless Stethoscope Amplified RF Stereo TV Listening Headphones System | Amplify Your Hearing for TV, Cell Phone, Computer, Tablet + More | 300’ Outdoor & 80’ Indoor Range

I've tried other (recognizable) brands, and this is by far the best ever for my needs. Easy to use, easy to set up (five minutes), customizable for my hearing loss. I'm a happy customer.

2/19/19:The unit stopped working after 6 months. Both the seller and the manufacturer were very good about honoring the included 2-year warranty (which was posted when I bought it, although I don't see it now). They gave me a choice of a free replacement or a full refund, and I chose the refund to try a different model.After a lot of searching, I gave up on finding a comfortable, wireless TV headset with balance and tone controls (and good customer reviews) to compensate for my hearing loss. Then I realized that "wireless" is the least important part of that idea to me. So now I have the "Syba Sonic SD-DAC63106 Stereo 3 Band Tone Control Pre-amp and Headphone Amplifier." There is an audio cable from my TV to my chair; a USB power cable from my computer system; no battery; and a good crisp sound with comfortable headphones I already had. This I recommend.11/10/18:I am lowering my rating after 3 months. The charging system does not seem to work consistently. Often after using the device, the charging light does not come on. Perhaps it only charges when the battery is very low. There is often a very loud crackling sound, which might be caused by a low battery. Also, over time, the discomfort of the weight on the ears and the dangling configuration of the device are becoming less acceptable. I will shop for an over-the-head type headphone set. Still, the tone & balance controls are excellent compensation for my hearing loss.8/14/18:I can highly recommend this device for performance, but can't comment on durability, having it only a few days. The rechargeable battery in the receiver can't be replaced. There is a 2-year warranty, and the extended protection plans might be a good deal considering the unknown battery life. I have moderate hearing loss mainly at high frequencies and one ear worse than the other. The tone and balance controls work well to correct for that, so I get a good crisp, centered sound. The tone control has three settings: flat, enhanced bass, or enhanced treble. That is limited flexibility, but the enhanced treble works well in my case. I like to watch TV while using my electric toothbrush, which buzzes in my head, without having to turn up the volume so loud that it would bother my neighbors. That's a pretty tough test and this does the trick very well. The optical audio cable is included with the unit. There is also a 3.5mm headphone input jack, but you would need to provide your own cable and adapter for other types of audio output jacks. The one downside of this model is the configuration with the receiver unit dangling like a pendulum under the chin. That is less comfortable and convenient than the over-the-head type. It tends to catch on an open collar; better with a crew neck shirt.

This review is for the Sonic Alert Stethoscope Amplified RF Stereo TV Listening Headphones System - CL7350 Opti. These headphones actually sounded better than I was anticipating for this type of product. It has a couple of really good use cases for amplified TV listening. First case is for those that may be hard of hearing, such as a family member that may have difficulty hearing the TV, doesn’t want to wear classic “hearing aids”, so has to crank the TV volume up really high. Which is of course probably much too loud for the rest of of the people in the room. The second case is where someone may want to listen to the TV, but the sound needs to be completely silent (or very low volume) for others in the room resting or studying.Don’t confuse these with attempting to use a baby monitor type of device that has a mic and paired speaker. In this situation, the TV volume still has to be on. With this device, it connects using the TOSLink optical cable directly to the TV’s audio output port, which means the TV volume can be completed muted or low, and this device will still work, including being able to independently adjust the volume on the headphones.The tone and adjustment capabilities of these headphones actually offer a lot of flexibility where you can boost either the lower or higher notes, depending on which sounds any given person may have difficulty hearing. You can also adjust the volume directly on the headphone device.Overall, these are definitely more geared toward TV listening, not music listening. The voices are really crisp and clear in the mid ranges, with good sounds on both the high and low ends for things like background music in a movie. I personally found it more realistic boosting the bass side when watching a movie.It does charge quickly, and you get a few hours of listening time after a full charge. This is more than enough time because frankly the weight of the headphones on the ears starts to become noticeable.These headphones are wireless, and just use the similar radio wave spectrum as a typical classic cordless landline phone. These are not “wifi” connected, nor do they need to be. They work just fine over tried-and-true no hassle radio wave frequencies for homes.The only thing that does give me a bit of a pause is that the rechargeable batteries in the headphones do not appear to be replaceable, so there is a potential longevity issue as the life of the batteries begin to diminish, but this is an unknown at this time.

I remember the old Sonic Alert commercials and generally thought it was a recognized brand name, so why not. However, it turns out this apparently isn't actually MANUFACTURED by Sonic Alert, although to be fair, it is sold on their website. It has a Geemarc brand that presumably Sonic Alert buys and resells. Thus, I'm not exactly sure who's providing the tech support/warranty for these.Sonic Alert started out in the 70's with a visual flasher for deaf/hard of hearing people. This unit feels like it was designed in the 80's, so it fits. It works ok, but audio quality isn't great. It has a charging base that connects to the headset wirelessly from a connected audio source using the provided optical cable, but while they support a headphone cable, they don't provide one. Although most of my high end components have S/PDIF optical ports, I'm not sure the average TV does. Of course if you have to use a headphone jack on your device, then you probably won't be able to get sound out of the device speakers.Beyond that, the headset is pretty heavy and can get uncomfortable over time. I'm not sure why these days they couldn't be creating a light headset. For that matter, you can get inconspicuous hearing aids that provide all of these features and more, so I'm not really sure where this fits in the market anymore.
