The DL107 SYS hearing loop system maximizes modern amplifier technology. Its network-control capability provides seamless, remote system set-up, operation, and monitoring of the induction loop system via a laptop or tablet. DSP audio processing offers flexible, powerful software control of mixing, equalization, compression, and more. Powerful Class D pulse-width amplifier maximizes the efficiency of the unit.

This assistive listening system’s design offers a single 9.5 A rms loop output for perimeter loop or single array configuration. A 70-100 V input connects to a distributed speaker/paging system, ensuring announcements are heard by hearing aid users and visitors using the two included body-pack loop receivers with earbuds.

Meet IEC 60118-4 standards on system performance when integrated into a correctly designed and installed system. The DL107 SYS is also tested to IEC Specifications 62489-1 Benchmark Standards.

Perfect, compact, portable, comfort.
Color: Grey, Size: Small
Got the small one. It's perfect size for camping. I saw other comments with pics of medium and looked too big for portable use. I like down feather pillows and this one is really close to same feel. I recommend it 100%. And I may even buy another one.

I really wanted to like this pillow but I didn't, My son did.
Color: Blue, Size: Medium
I bought two of these Medium pillows for summer camp that my son and I went to this year. Let me start by saying the only reason I don't like it is because its too soft and small for me. By soft I mean the pillow bottoms out when I put my head on it. I measured and it is 4" thick but when I put my head on it, it almost disappears. They could add 20-25% more stuffing and it would be great. My son liked his, I didn't even bring mine. What I did do is stuff a standard size memory foam pillow in the stuff sack and used that! The quality of this pillow is great, the seams were not torn or coming undone like some people said, no rips or stains. the zippier works just fine and IT IS MEMORY FOAM, people who complain that it's not are expecting a brick of foam which this isn't, it is shredded/torn memory foam filling that is exactly like my $60 memory foam pillows that I use on my bed. TLDR its great for kids, not for people with bowling balls for heads like me. WISE OWL, ADD MORE FILLING ! I was able to stuff a pillow 3x the size of this one in the same bag.

Comfy!
Color: Black, Size: Medium
It's very comfortable. It's a good size and thickness. I wish it had a strap to hold it on to your air mattress or cot. Good value!

I purchased the toddler size as a back support pillow. Quality! Firmness!
Size: Kids 13"x18", Number of Items: 1
I LOVE this pillow! OK, I admit that I just got it and opened it, but I already know I'm going to love it. I purchased the toddler-sized pillow to use behind my back in the car or on an airplane - or maybe just a snuggle pillow in the bed - a tiny version of a body pillow. I got exactly what I wanted! This pillow is exquisitely crafted, and I can feel the cooling quality already. I purchased a brand new silk zippered pillow case for it. I inserted the pillow in the case right away because I know it's going to expand over the next 72 hours - to the perfect firmness, I hope. I'm afraid if I wait until tomorrow it might not be able to fit into the pillowcase! Some people here have reported a distaste for the firmness of this pillow, but I'm looking forward to it. So, I recommend if you want to really firm pillow, you had better put it right in the pillowcase when you get it, because you might not be able to stuff it in if you wait 72 hours! By the way, this pillowcase has absolutely zero smell, so don't bother your sleepy head about that.
