  1. Satisfied Review by MrL
    Overall Satisfaction

    Works great, finally! My system needed the converter to operate. The instructions sucks and I was directed to watch a video for setup. Problem is, my Internet connection is so bad that I can't watch a video without buffering every 18 seceond - yes, I know, I'd pay anything for a better one but they ain't available in this area. So, I watch the video at the library, took notes, bought 2 converters before finding one that worked and finally, after 5 or 6 weeks, got it to work. 5 stars for the product, 3 stars for poor printed directions and forcing buyers to other sources, final score on this review: 4 stars.

  2. Ease of use, Longevity of Sound, and seeming Durability Review by HearingWell
    Overall Satisfaction

    It exceeds my anticipation because other items - including classical hearing aids - were/are more cumbersome and expensive! (Posted on 2/15/2016)

  3. It does the job Review by Jack
    Overall Satisfaction

    Honestly it is better than I expected. I lost one of the ear pieces, but the is another set in the box. Sound quality is not top notch, but I can now hear the television. It's all good. (Posted on 1/12/2016)

  4. Good peacemaker Review by LB
    Overall Satisfaction

    I bought the unit for my hard of hearing husband, who was beginning to turn the TV volume to painful levels. He can now hear at his preferred volume without driving me crazy. His only complaint is that the ear buds are not comfortable. (Posted on 12/31/2015)

  5. Worth the price Review by Wally
    Overall Satisfaction

    Very easy to set up. Easy for people in their 90s to use. Not a 5* sound but that was not expected at the price it sells for. The microphone is of little use. (Posted on 12/17/2015)

  6. easy to set up and use Review by GiGi's headphones
    Overall Satisfaction

    Thank you for offering a product that works and is easy to set up. (Posted on 11/25/2015)

  7. Good features, poor quality Review by JHB
    Overall Satisfaction

    Works great out of the box, but then fell apart. Very poorly made china product. Screws holding headset together either broke the sockets, or the sockets wouldn't hold. I am trying to have the headset replaced by warranty, but we will see how that goes. (Posted on 10/29/2015)

  8. Works well and comfortable Review by Rog
    Overall Satisfaction

    Only one negative. When room mike is on it kills the TV sound, so you are audibly out of touch when watching TV. (Posted on 9/23/2015)

  9. Works great/the ear piece is uncomfortable Review by Sheila
    Overall Satisfaction

    The sound quality is perfect for my purposes. The ear piece is heavy, though and hurts my ears after using it for a while. I haven't used any other listening device, so I can't make a comparison, but overall, I am very satisfied with my purchase. I can deal with the ear piece. (Posted on 9/23/2015)

  10. Great product; poor instructions Review by Bill
    Overall Satisfaction

    Completely satisfied with the product. In all aspects it is a marked improvement over TV Ears including sound quality, design, looks and reliability. I only give it 4 stars because of the poor instruction manual. No explanation at all on what the Mic is for and how to hook it up.
    Also applaud your return policy. Had to use it because of a defective power supply and it worked well. Thank you.

    Overall Satisfaction

    This was better than I hoped for! Easy to install and great sound quality. If/when it wears out, I will get the same thing again. (Posted on 5/11/2015)

  12. Exelent product Review by Sankab
    Overall Satisfaction

    I bought the Unisar DH900 for my elderly mother and it had emproved her live greatly! Mom is happy that she can clearly hear her TV and, I think, her neighbors are even happier because she doesn't blast the volume any longer. It's very easy to install and even easier to use. Thanks for the great product!!! (Posted on 3/31/2015)

  13. A fine unit Review by Marv
    Overall Satisfaction

    I just received this unit and it is a fine piece of equipment.
    The sound quality is first rate. The ear plugs should be a bit softer. (Posted on 1/6/2015)

  14. 3 stars Review by Gib
    Overall Satisfaction

    Looks nice eady to install though instructions are not very detailed. When you switch to the mic, the beep is way too loud; it hurts my ears! Earbuds are hard and the unit is heavy making my ears sore. The volume control is affected by the volume on the TV; not a good situation. (Posted on 8/5/2014)

  15. Very nice. Agree about the ear buds Review by Of
    Overall Satisfaction

    What the heck is the external mike for. Your manual did not explain its use or placement

    Harris Communications response: Thank you for your review. To answer your question, the external mic allows you to hear someone talking to you without having to remove the headset receiver. It mutes the TV. If you have any additional questions, please contact us. (Posted on 7/25/2014)

  17. My Mom Can Finally Hear the TV Review by Geri-Ann
    Overall Satisfaction

    My mother is extremely hard of hearing, even with hearing aids. For years, she's used TV Ears, but she missed half of what was going on. The static was terrible. I bought a pair of these, hoping they'd work better for her. They work perfectly! The sound is exceptionally clear. Having an extra battery is great. I've ordered 3 more for her house. (Posted on 7/8/2014)

  18. Best purchase Review by MaryM
    Overall Satisfaction

    This was recommended to me by a friend and I immediately purchased it. I wasn't all that sure what to expect, but have been completely happy and satisfied. It's amazing that I can turn the sound down and be able to hear where as before I had to turn sound up to the highest on tv and sometimes that didn't even work. I don't have a problem with all shows, but ones I did, have been happily solved. I was able to recommend this to a relative and friend after my rave reviews. Thank you (Posted on 4/29/2014)

  19. Excellent Amplification/Ear Piece Needs Work Review by Nancy
    Overall Satisfaction

    The sound quality on this system is exceptional. It's a bit heavier than others I've tried and I agree with a previous reviewer that the ear buds need to be more flexible/softer. I have sensitive inner ears and between the slight additional weight and hard rubber, I find myself adjusting them often. That said, it's small price to pay for such excellent and adjustable sound.

  20. A happy wife is a happy life Review by Don
    Overall Satisfaction

    My wife can hear a mouse sneeze a hundred feet away, I am not that fortunate. This unit has been a blessing, no longer do I have to listen to the programs as though the actors are whispering. This is a great product.

  21. best product I've had Review by kyfarmer
    Overall Satisfaction

    TV viewing involved blaring sound or not hearing a word. Now everyone can enjoy. Had other products but this surpasses others in their clarity of sound, comfort, and ease of use. Highly recommend Unisar DH900 (Posted on 2/25/2014)

  22. Good Product Quality Unit Review by Robert
    Overall Satisfaction

    I could not be more pleased with this listening device. I have a damaged left ear drum and normally hear about 10 percent or less of the volume I hear in my right ear. The balance control on this unit allows me to adjust the output volume to sound equal in each ear. Good bye closed captioning; it is nice to hear TV again.
    Watching TV, the sound output is clear and noise-free, though in the room listening mode there is a slight hollow or echo sound that does not bother conversation. I have not experimented with the tone control as the default setting is perfect for me.
    The Unisar DH900 is new to the market and I was reluctant to buy as I could find only 2 consumer reviews at six or eight merchants. Two weeks later, I see six, all at Harris Communications and all 5 stars. One reviewer thought the ear buds NOT adjustable. The ear pieces DO swivel 360 degrees inward, but the ear bud covering the ear piece makes it a little stiff to adjust.
    During my research I was shocked at the cost of replacement parts for TV EARS. I saw prices of $19.95 for 5 pair replacement ear buds and $24.94 for a replacement battery. The ear pieces for the DH900 are one quarter inch in diameter and would use a large standard replacement ear bud (12 pair for $6.95) at earphones though an extra pair of ear buds and an extra battery ships with the unit.
    Both batteries can be charged together. They are fast charging and the charging diode goes from red to green in one hour or less. However Unisar recommends a three hour charge prior to use. It uses a MLP503131P 320Ah 201343 battery that I have been unable to find. I see a very similar battery with like numbers made in china.
    I think this device is headed for a major share of the TV listening market. I was lucky to find it on sale for $84.96. Now all is see are $99 prices, which is still a great buy.

  23. Good but ear pieces need redesigned Review by Bobbie
    Overall Satisfaction

    After 3 t.v. ears that don't hold up I was pleased to see that this seems to be better quality and it works very well. However my one complaint is that the earphones are too stiff, hard and not adjustable.. I found that putting them so they are on my head rather than hanging down is more comfortable on the ears. (Posted on 2/11/2014)

  24. very pleased Review by Fred
    Overall Satisfaction

    Very pleased with the Unisar DH900. Have had Sennheiser wireless head phones at more than twice the cost. Like these ones as well. Hope they last longer (Posted on 2/4/2014)

  25. Excellent product Review by george
    Overall Satisfaction

    For years I have used [...]. They are poorly made with the temples breaking at the battery area, I received my DH 900 last week and it is great. Wish I had this aid years ago. Well built, sturdy and the radio waves are heard all over the house. The cost is a super deal. George (Posted on 2/3/2014)

  26. A Real Problem-Solver! Review by mothra7
    Overall Satisfaction

    My husband always has the tv turned up so loud! I looked into "TV Ears", but the reviews were mixed so I decided to investigate other options. I found this website and ordered the product.

    It performs so well and eliminates the tug-of-war that surrounds tv volume in our home. Thanks for a great product! We love it! (Posted on 2/1/2014)

  27. excellent. Review by I don't even know what this means!!!!
    Overall Satisfaction

    I am hard of hearing and needed this item very much. I am really enjoying it. Thanks very much.. Carolyn Webb (Posted on 1/6/2014)

  28. Works well and convenient Review by jzweig
    Overall Satisfaction

    I bought this for my mother who worries about turning the volume up too high on the TV early in the morning or late at night. She used to read closed captioning all of the time. Now she can watch and listen to the music in the shows. It sounds great and connects very easily. I like the extra battery and charging compartment. My mother loves it also because they are not earmuffs. (Posted on 1/3/2014)
