SHIDU Portable Wired Voice Amplifier (18W) with 1200mAh Lithium Battery and Wired Microphone for Teachers, Tour Guides, Yoga Instructor and More (Black 512)

Good little amplifier that takes a microphone or an auxiliary feed and produces a good quality sound. It used in my role as Quizmaster to assist with projecting my voice so that all in the venue can hear clearly and also assists with a music round. Good bit of kit.

I used this to project my voice when calling a couple of country dances at a class this evening. It worked perfectly well. V pleased with it.

Nothing special, sound average.

 I sometimes work with my local school, and the times in assembly I have to force my voice, so the entire hall of 400 children can hear me is… frustrating.But as soon as this super mini amplifier turned up, it gave a big turn to my plans.As this mini voice amplifier has many more uses.And no… I don't use it to call my kids at home, as the problem is not hearing me, it's actually doing what I say, ha, ha, ha (Yes I did give it a go)My ten year old who loves singing closes the door of her room, plugs her phone to the amplifier, puts on her headset and… Feels as she's in a professional recording studio ;)I wonder if she actually knows that all the neighbours can hear her lovely singing, ha, ha.A lot of fun for her, and very practical for me too.What a purchase!PROS-BatteryThis voice amplifier has a 1200 mAh rechargeable battery.When it arrived it came with some battery.I recommend you fully drain your battery before fully re-charging again.Once the battery was drained (my daughter took good care of that) I put it on charge.The UK 3 pin plug charger comes included with an amazing 150cm / Just over 59" cable.When on charge a red blinking light comes on.I was expecting the light to turn green, but it doesn't .Once the battery is fully charged, the light will turn on solid red.So don’t wait until it turn green, or the battery will simply get fried.Normal charging time is between 3 to 5hoursThat will give you a 6 to 10hours performance.-PerformanceThe microphone is sensible to the smallest sound, so yes, this voice amplifier works and works extremely well.I am actually rather impressed with the sound quality, specially taking into account the headset is only mono sound.As the headset included is mono sound, you can plug in any other headset or a mic you might have (as long as it comes with a 3.5mm Audio jack)*Personal tip;When turning on, make sure the unit and the MIC are well apart from each other or you will go crazy with a very high pitch noise.-HeadsetHeadset is basic and as mentioned is mono sound, but it does the job for a conference or public speech just fine.The earpiece sits on top of the ear, while the mic can be adjusted to any desired position.-OperationYou can insert TF Memory cardsPlay directly from any device using an Aux Audio Jack cable.Connection can be achieved with many devices including MP3/MP4, PC, Phones, which is fantastic.You can even have a TF Memory card and a MP4 plugged in at once and alternate between them (with M mode)Do not worry because the voice amplifier comes with plain English instructions that explain everything really well.On the card reading mode you will even be able to shuffle and change your songs directly from the mini amplifier with the <<< and >>> keys. ;)-PortableThe best part of this amplifier is that its fully portable.It comes with an adjustable strap.The strap can be adjusted to a max. of 120cm / 47.25" and a min. length of 63cm / 24.75"The unit itself only measuresHeight 9.5cm / 3.75"Width 8.5cm / 3.6"Depth 3.4 cm / 1.3"-Ports on amplifierCharging portTF cardUB entryMICAUX-What will you receive:1 x Mini Amplifier1 x Adjustable strap1 x Wired microphone (mono sound)1 x Audio cable (53.5cm /22" in length)1 x 9V 3 Pin UK Wall Charger (150cm /* Just over 59" cable)1 x User manualCONSNoneIf you have any questions, that you think I could help, just click on the comment box below and I will do my best ;)Please take into account that even though I received this order at either a discount or without a cost for my own evaluation, I can assure you that, that has not influenced my opinion in any way. I only accept / request items that I'm interested in and as you have seen by my review, or any previous ones I have done, I always mention the good and the not so good/cons (if any).This is an awesome gadget, and I definitely received much more than I was expecting due to its price.I would very highly recommend for performance, different modes of use and of course… Quality of sound for such a small amplifier.Thank you for reading and watching. I hope you found this review helpful.[...]

Ordered a Winibridge but instead was sent the Shidu. Used just once. Very good sound but in the middle of second usage went dead.

I ordered this to use when giving presentation to a large number of people at work in a large hall. Until now I have used a hand held mic, but this means that your hand is not free and it has a knock on effect on your movement and body language. The product arrives well packaged in a good looking retail box. Inside is the amplifier (which measures just under 4” square by just under 2” wide), a wired microphone, audio cable, charging cable, 9V wall charger, 3.9ft waist band and full instructions. I ordered the black so all parts are black. The amplifier contains a 7.4V 1200mA lithium battery which holds enough charge for up to 18 hours of use after a 5-hour charge. Output power is 18W and sound will carry up to 2,000sq m, or 21,500sq ft which is quite some distance. Love the look of this device and the fact that it is not too imposing, and is in fact quite discreet. Sound quality is great as is amplification. I would definitely recommend this product to others.*I was offered this product at a discounted price in return for my honest and unbiased review which is what I have given here*
