In one sentence, describe what the following article is about: DACs convert your phone's digital sounds to analogue; while every phone has a built-in DAC, purchasing an external one will both boost the power of the analogue sound and enable you to attach otherwise incompatible hardware-- in this case, a standard set of 3.5 millimeter headphones. Some popular DAC options include the following: Chord Mojo - A large DAC with a secondary headphone input that plugs into your phone via USB cable ($599 USD). While considered fairly high-quality, the size of the unit and overall price are common complaints. AudioQuest Dragonfly - Another USB DAC with a headphone jack. Comes in standard Black ($100 USD) or the higher-quality Red ($198 USD) models. Common complaints include poor volume control and less refined audio than more expensive counterparts. Arcam MusicBoost S - A DAC built into an iPhone 6 and 6S case ($190 USD). Common complaints include it's limited compatibility (it won't work with a 6 Plus or 6 SE), mandatory charging and limited improvement to sound quality. Make sure your DAC supports a 3.5 millimeter set of headphones before purchasing it-- while most do, you don't want to order an expensive piece of hardware only to find that it doesn't work with your technology. Amazon is a reliable source from which to purchase technology if you plan on ordering online. This should go into the Lightning port at the bottom of your phone. Depending on your model, you may have to complete an installation on your iPhone's screen. The headphone jack location will vary depending on your DAC model. You'll need to fine-tune the DAC's volume since DACs tend to have higher-quality audio output than standard 3.5 millimeter ports. This will open your iTunes library. This should begin playback; if you can hear your music, you've successfully used headphones with a DAC on your iPhone 7! If you can't hear anything in your headphones, try adjusting your phone's volume. You should also check your headphones' connection to the DAC, the DAC's connection to your phone, and any volume options on the DAC itself.
Summary: Research digital-to-analogue converter options. Purchase your desired DAC. Plug the Lightning end of the DAC's cable into your phone. Plug the USB end of the DAC's cable into your DAC. Plug your standard headphones into the DAC's other end. Place your headphones in your ears. Unlock your phone, then tap your "Music" app. Tap a song.

Since viral conjunctivitis is not curable, it can recur after initial treatment. These flare-ups are often caused by stress. Therefore, you should identify and remove potential stressors in your cat's environment. For example, keep your cat's daily routine as steady as possible. If you have multiple cats, make sure each cat has her own 'supplies' (e.g., food and water bowls, toys, litter box) to reduce bullying or fighting between cats. Your cat may also feel stressed if she becomes bored. Provide her with plenty of toys and rotate them on a regular basis. Puzzle toys are especially useful for keeping a cat busy and entertained. Herpesvirus requires an amino acid called arginine to replicate. However, when the amino acid lysine is present, the virus will take up lysine instead of arginine, which will stop the virus from replicating. Your veterinarian can recommend a specific oral lysine supplement for your cat. Lysine can be used as a lifelong management option for feline herpesvirus conjunctivitis. The severity of a herpesvirus conjunctivitis flare-up can be reduced with ocular (not injectable) vaccination. The vaccination works by strengthening the immune system and making the flare-up more bearable for your cat. Discuss this vaccination option with your veterinarian. If your cat's allergies caused her conjunctivitis, then you should reduce her to exposure to the offending allergen as much as possible. For example, if she is allergic to dust, you will need to dust your home more frequently. If she is an outdoor cat, you may need to keep her indoors and away from outdoor allergens like pollen. If your cat's eyes became irritated when you used certain household cleaners, try keeping your cat away from the area where you are cleaning. If your cat's eyes start to look swollen and red, and you see colored discharge (e.g., green, yellow) coming from her eyes, your cat is likely experiencing a conjunctivitis flare-up. Other signs of a flare-up include increased tear production, squinting, and sensitivity to bright light. When your cat experiences a flare-up, contact your veterinarian about the best way to manage it.

One-sentence summary -- Reduce your cat's stress levels. Supplement your cat's diet with oral lysine. Consider vaccinating your cat. Minimize your cat's exposure to allergens. Look for signs of a flare-up.

Q: If you want to gain any length on your hair, don't cut it. Trim it 1/8th inch to even out the ends but that's all. A curling iron is one of the most damaging instruments used on African American hair types. When a curling iron is used on your hair, the barrel cover clamps down on your hair causing a weak point. With repeated use the hair shafts eventually break along these areas made weak by the curling iron. If you want longer hair, it is imperative that you stop using a curling iron to style your hair. Curling irons make hair, weak, dry and very thin. Instead try using curlers or keeping your ends evenly trimmed and simply wearing your hair down.
A: Don't cut your hair much. Avoid the curling iron.

Problem: Article: Don't keep kissing them for more than a few seconds. Stop and put a little space between the two of you. Take a moment to breathe and think about what happened. It's okay to go back in for another kiss, but it's best to take a little break first. Remember, the other person is likely just as nervous about kissing as you are. Show them you liked it by looking at them and smiling. You might also hold their hand or put your arm around them. Make eye contact, then lean in close again. Watch to see if they're leaning in, too. If you're in doubt, ask them if they want another kiss. Say, "Are you ready for another kiss?" or "Can we do that again?" Only go in for another kiss if you want one. Don't feel pressured to kiss if you don't feel like it. After the kiss, spend some time being intimate without kissing. Hold them in your arms, snuggle up next to them, or hold hands. Do what feels comfortable for both you and your kissing partner. Relax and enjoy this time together. You might watch a movie, talk, or go for a walk. You might feel overwhelmed or nervous right after your kiss, and that's okay. On the other hand, you might feel really excited and chatty. Either way, talk to your kissing partner about what happened when you feel ready, whether it's right after the kiss or later in the day or night. For instance, say something like, "I've been wanting to do that for a really long time," "That was nice," or "You're a good kisser." Don't feel like you have to say something right away. It's okay to wait. Text, call, or talk to the person you kissed to check on how they're doing. Let them know if you're interested in going on another date or hanging out with them again. Additionally, tell them if you enjoyed the kiss. Keep in mind that having a first kiss doesn't mean you always have to kiss. It's okay to decide you want to wait awhile to do it again. On the other hand, it's perfectly normal to be excited about the chance to get another kiss. Say something like, "I had fun last night. The kiss was nice. Do you want to walk me home from school tomorrow?"
Summary:
Pull away to give you both a chance to take a breath. Smile at them to show them you liked it. Go in for a second kiss only if they seem ready for it. Cuddle or hold hands for several minutes afterwards. Say something about the kiss when you're ready. Follow up with your kissing partner the day after your kiss.
