FIIO's newly self-developed four-channel fully differential 24bit R2R DAC consists of 2x 48 precision thin-film resistor arrays per channel, totalling 192 resistors with 0.1% tolerance and low temperature drift(30ppm). This configuration delivers a unique and charming sound.

The K11R2R employs a fully differential architecture, resulting in lower noise, with less FFT harmonics and a darker music background compared to typical ones.

The NJW1195A is a 4-channel electronic volume controller. The resistor ladder electronic potentiometer is low distortion and low noise, allowing precise volume adjustment.

3 gain levels+ 3 independent volume curves
The 3 independent gain levels and volume curves allow the K11 R2R to give you a better listening experience with various types of headphones, whether you are using sensitive earphones or harder to drive over-ear headphones.

The capacitors' ultra-low ESR, combined with excellent anti-interference capabilities, allow them to provide a stable and clean power supply and thus achieve high-quality sound.

Only SPF 15. Best For Overcast Days or Less Exposure.
I love Coppertone Sport sunscreens because they stay on longer than many and don't drip painful lotion into my eyes when I sweat. This spray-on version is only SPF 15, so, as a fair person, I can use it in direct sun only for 30-60 minutes of exposure or if I'm outside during an overcast day when, yes, I can still burn. SPF blocks 93% of the sun's rays, which sounds like a lot until you consider that SPF 50 blocks 98% of the rays. Sprays like this are especially useful if I'm by myself and need to reach difficult places such as my back. For the rest of me, I spray my skin, then rub in for complete coverage. For my face and neck, I spray into my hands, then apply to those areas. You don't want to spray directly on your face when you can inhale it or get it in your eyes. If you don't have sun-sensitive skin or don't expect to be in direct sunlight for long, then this is a great option for easy application. Just make sure you apply enough of it and reapply throughout the day. -- Debbie Lee Wesselmann

Summer Essential at great price
Great deal ahead of the summer sun. Product was the perfect match for my golf trip. Felt like it held up even in the heat and sweaty environment.

Great sunburn protection for beach days
Style: Sunscreen Lotion 70 SPF, Size: 6.7 Fl Oz (Pack of 1), Style: Sunscreen Lotion 70 SPF, Size: 6.7 Fl Oz (Pack of 1)
If you burn easily like I do, this sunscreen is an absolute lifesaver. I used it during a full day out in the intense sun and beach heat, and it protected my skin perfectly—not a single spot of redness! What I love most is that it works beautifully for both the face and body. It applies smoothly, absorbs quickly, and doesn't leave that heavy, suffocating white cast that a lot of high-SPF sunscreens do. It also handles sweat and water incredibly well without running into my eyes and stinging. It has a nice, subtle beachy scent that isn’t overpowering. This is officially my go-to sunscreen for outdoor activities!

Lightweight, Effective & Smells Great
Style: Sunscreen Lotion 70 SPF, Size: 6.7 Fl Oz (Pack of 1)
This sunscreen works amazing! The Neutrogena Beach Defense SPF 70 gives excellent sun protection without feeling too heavy or greasy on the skin. I really like that it doesn’t have a strong overpowering smell like many other sunscreens. It’s lightweight, absorbs quickly, and feels comfortable for everyday wear or beach days. The water resistance is great and it protects well even during long hours outside. Perfect for the whole family and definitely worth buying again!

This sunscreen is a great everyday option, especially for the price. It provides strong sun protection without feeling heavy or greasy. I like that it works well for both face and body, which makes it convenient to carry just one product. It also has a nice moisturizing effect, so my skin doesn’t feel dry after applying. The lotion spreads easily and absorbs quickly, which is perfect for busy mornings or beach days.
