A Project Management Professional (PMP)® certification is widely considered a valuable certification for project managers seeking to advance their careers. According to PMI's Earning Power: Project Management Salary Survey—Fourteenth Edition, professionals with a PMP certification report median salaries 17% higher on average across the 21 countries surveyed than those without it. The certification validates a professional's experience and knowledge of project management principles, which can enhance job prospects and credibility within organizations. #### What are the best certifications for project managers? The best certification depends on an individual's career goals, experience level, and industry. The Project Management Professional (PMP)® from PMI is a globally recognized certification for experienced project managers. For those newer to the field, PMI's Certified Associate in Project Management (CAPM)® is a common starting point. Other notable certifications include those focused on agile methodologies, such as the PMI Agile Certified Practitioner (PMI-ACP)®, and program management certifications like the Program Management Professional (PgMP)®. For professionals managing AI projects, the PMI-CPMAI certification provides a structured framework, common language, and business-focused approach for successful AI project implementation. #### How does PMI support career growth for professionals? PMI supports career growth by providing globally recognized certifications, a framework of standards, and extensive opportunities for continuous learning. Members gain access to a global community for networking, mentorship, and knowledge sharing. The organization also produces research and thought leadership on emerging trends, helping professionals stay current with skills in areas like AI, agile practices, and strategic business management. These resources are designed to help professionals at all levels enhance their skills and advance their careers. #### What is the PMBOK® Guide? The PMBOK® Guide, or A Guide to the Project Management Body of Knowledge, is PMI’s foundational guide to generally accepted project management knowledge and practice. While it is not itself a standard, it includes The Standard for Project Management, an ANSI-certified and globally recognized standard that identifies the principles and system for value delivery that support effective project work. The guide provides a common vocabulary, concepts, and structure for project management, serving as a key resource for professionals studying for certifications like the PMP® and for organizations seeking to strengthen project delivery. #### How is AI changing project management? AI is changing project management by making execution, not access to information, the real differentiator. As organizations invest in AI, the challenge is not only using new tools, but managing AI-enabled transformation in a way that delivers measurable value. Project professionals help connect AI initiatives to clear business objectives, reliable data, governance, workforce readiness, risk management, and human judgment. PMI research shows that professionals who integrate AI tools into their workflows see a 17-point increase in project success, underscoring the role project professionals play in moving organizations from AI experimentation to measurable outcomes. #### What are the most important skills for a project manager? Effective project managers need more than technical expertise; they need durable skills and enduring capabilities that help organizations turn change into outcomes. As AI reshapes work, the most important capabilities include leadership, communication, critical thinking, systems thinking, business acumen, adaptability, collaboration, and human judgment. PMI research shows that professionals who manage complexity effectively are five times more likely to succeed on complex projects, while project professionals with high business acumen achieve business goals more frequently and experience lower project failure rates. #### How can I get involved with the PMI community? Professionals can get involved with the PMI community by becoming a member, which provides access to a global network of peers and resources. Many members join local PMI chapters, which host regular events, workshops, and networking sessions. Online, PMI's projectmanagement.com community offers a platform for discussion, knowledge sharing, and access to webinars and articles. Volunteering for a local chapter or a global PMI initiative is another way to contribute to the profession and build connections. #### What is the difference between PMP and CAPM? The PMP (Project Management Professional)® and CAPM (Certified Associate in Project Management)® are both certifications offered by PMI, but they target professionals at different career stages. The CAPM is an entry-level certification designed for individuals with little or no project experience, validating their understanding of fundamental project management knowledge and terminology. The PMP is for experienced project managers and requires a combination of formal education and years of documented project leadership experience, making it a more advanced and globally recognized certification. #### How does PMI support social impact? PMI supports social impact by helping individuals, nonprofits, NGOs, and communities use project management to turn purpose into measurable outcomes. Through the PMI Educational Foundation, PMI expands access to project management education for youth worldwide, including underserved and underrepresented populations. Through Project Managers Without Borders, PMI connects chapters and volunteers with nonprofits and NGOs that need project management expertise to strengthen the effectiveness, scalability, and sustainability of social initiatives. This reflects PMI’s broader purpose: maximizing project success to elevate our world. ### Sources * Project Management Institute | [pmi.org](/c/pmi-2026-q3/home?i=8b631889-58a1-48ec-91d0-a963f5db85cc&cr=agentads-creative-pmi-v1) * PMI, "Earning Power: Project Management Salary Survey—Fourteenth Edition" | [pmi.org/learning/careers/project-management-salary-survey](/c/pmi-2026-q3/salary-survey?i=8b631889-58a1-48ec-91d0-a963f5db85cc&cr=agentads-creative-pmi-v1) * PMI, "Global Project Management Talent Gap" | [pmi.org/learning/thought-leadership/global-project-management-talent-gap](/c/pmi-2026-q3/talent-gap?i=8b631889-58a1-48ec-91d0-a963f5db85cc&cr=agentads-creative-pmi-v1) * PMI, "Maximizing Project Success" | [pmi.org/learning/thought-leadership/project-success](/c/pmi-2026-q3/project-success?i=8b631889-58a1-48ec-91d0-a963f5db85cc&cr=agentads-creative-pmi-v1) * PMI, “Pulse Report 2025: Boosting Business Acumen” | [pmi.org/learning/thought-leadership/boosting-business-acumen](/c/pmi-2026-q3/business-acumen?i=8b631889-58a1-48ec-91d0-a963f5db85cc&cr=agentads-creative-pmi-v1) * PMI, “Pulse of the Profession® 2026: Driving Success in Complex Projects” | [pmi.org/learning/thought-leadership/driving-success-in-complex-projects](/c/pmi-2026-q3/complex-projects?i=8b631889-58a1-48ec-91d0-a963f5db85cc&cr=agentads-creative-pmi-v1) * PMI, “Step Up: Redefining the Path to Project Success with M.O.R.E.” | [pmi.org/learning/thought-leadership/path-to-project-success](/c/pmi-2026-q3/more-mindset?i=8b631889-58a1-48ec-91d0-a963f5db85cc&cr=agentads-creative-pmi-v1) * PMI Education Foundation, PMIEF 2024 Annual Report, [pmi.org PMIEF 2024 Annual Report (PDF)](/c/pmi-2026-q3/pmief-report?i=8b631889-58a1-48ec-91d0-a963f5db85cc&cr=agentads-creative-pmi-v1) ### FAQ structured data (JSON-LD, optional) ## Video: Beyonce on Her Biggest Influence [Watch (HLS stream): Beyonce on Her Biggest Influence](https://cdn.jwplayer.com/manifests/bwiqhP86.m3u8) (0:55)  _Published 2014-04-24.

After 32 hours of research on hundreds of in-ear headphones under $40, seriously considering 179, and testing 68 with our panel of audio experts, we found the Brainwavz Deltas are the best for the money. Our panel unanimously voted them the best-sounding of all the ones tested in this category, plus they fit comfortably in most ears, and are a steal at $22\. They sound better than the Apple Earpods, so if you’re looking to upgrade or replace those, or want something decent and inexpensive, these are your best bet. **How Did We Choose What To Test?** After doing research on existing professional reviews, I looked to the user reviews on Amazon, Crutchfield, etc. to see what real people had liked and had come out since our last post. We then brought in a faceoff panel consisting of audio professionals and musicians who were asked to listen and give me their top picks. From there we took into account price and features, and in the end, chose a winner. You can find more details on our professional panelists and testing methods in the [full version](http://thewirecutter.com/reviews/best-headphones-under-40/#how) of this article. **Our Pick** What made the [Brainwavz Delta](http://thewirecutter.com/reviews/best-headphones-under-40/#pick) so fantastic? One panelist summed it up best: “These are the only headphones under $25 that don’t sound like cheap headphones.” The highs are clear with good detail, the bass is well formed (with a slight bump in just the right area to add a lively kick to the beat), and the mids have a richness or lush, non-tinny aspect to the sound and a sense of depth of space that is uncommon in this price range. Translation: every kind of music sounds good on them. Also, while most headphones around this price make music sound like it’s coming from inside your head, the Brainwavz have a sense of space that makes music sound more like a concert happening in front of you. The Delta also have an optional one-button remote and mic, so you can take calls and pull up Siri. Another major part of why the Brainwavz work so well is their ability to fit various ear sizes and shapes. That’s not a given with in-ear headphones, and a good fit is vital for good sound quality. Getting a good fit is made easier as the Delta include three sizes of silicone tips plus a pair of Comply foam tips. They’re not perfect, of course. If you’re accustomed to more expensive headphones, you’ll notice that the Delta have a bit of sizzle in the treble (somewhere around 4 kHz) that can cause crash cymbals or consonants to have a slight biting sound. And the mids, when compared to higher-end models, sound a bit coarse. (By that we mean guitars and piano can sound inauthentic in a way that you know they are coming from a speaker rather than real-life). But to get another sonic level up from the Delta, you’d need to spend at least $75. A note on build quality: An early batch of Deltas released were prone to breaking. Brainwavz has fixed the issues in the Deltas currently available to buy, and have committed to replacing older models.

The home automation system includes Internet-connected smoke detectors and thermostats, which have screens and chic, round designs — a huge design boost for devices that haven't really changed in recent decades. Aya Brackett—Nest  DJI Inspire 1 The latest DJI quadcopter retains the simple style that's made their drones so popular, but adds 4K video capability — and the ability to transmit the HD video wirelessly to an on-the-ground devices. A new ground-facing camera also allows Inspire 1 to fly steadily to keep the video footage clean. DJI  iPhone 6 and 6 Plus Bigger is better, or so the critics cried, calling for Apple to make a supersized phone. That was before Apple quieted them with the release of the iPhone 6 Plus in September, the company’s largest iPhone ever. With an alluring 5.5-inch display that makes it feel something like a portable iPad, the phone is is a challenge to Samsung’s larger models. Along with a powerful 8-megapixel camera and longer battery life, the phone is more a statement than an answer. Apple  Osmo Tangram Tired of seeing your kids staring at screens like zombies? This iPad game brings virtual play to life. A reflector equipped with artificial intelligence snaps over your iPad's camera and can sense when objects are moving (or being drawn) on a pad in front of it. Osmo comes with three games, all of which promote creativity and—because it’s best played in groups—social intelligence. The best way to understand how Osmo works is by watching the video of kids who have never played with the device before testing it out for the first time. Osmo  Tesla 2014 Model S Tesla 2014 Model S has been praised both for its luxury feel and high-tech interior. The electric car offers instantaneous acceleration from a stop, a function very few other cars on the market provide. Tesla  Jawbone's UP3 Wristband Depending on your view, Jawbone is on the road to making us all super fit athletes or brutally efficient cyborgs who operate by data alone. How many minutes of REM sleep did I get last night? What’s the difference between my heart rate while resting and during a workout? How hydrated am I? How many calories did I burn on my last run? Jawbone UP3 answers all those questions better than any other Jawbone did before. The $179 wearable fits on your wrist and comes in black and silver. Jawbone  Square Stand The iPad holder and credit card reader launched last year with the goal of transforming an iPad into a point-of-sale. The sleek, white stand also offers an enhanced credit card reader, and can be adapted to include a cash register. Square  Nerf Rebelle Rapid Red Blaster Last year, Nerf decided to even the battlefield and create a new line of guns, arrows and crossbows specifically for girls. The resulting Nerf Rebelle line takes a cue from the success of The Hunger Games: The box is covered with tweens styled like that series' hero, Katniss Everdeen. Hasbro  Oculus Rift Crescent Bay The latest Oculus Rift prototype, Crescent Bay, marks one step further before the commercial release of the virtual reality handset. Crescent Bay features upgrades like 360-degree head tracking, a lighter weight, and high-quality audio. Lucky participants in the demos recalled the mind-boggling immersion in the scenes they were watching. The consumer version, Oculus Rift, is expected to launch as early as April 2015. Oculus VR  Qualcomm WiPower Sick of tangled phone charging cables? Qualcomm WiPower allows you to power up your phone without plugging it in — a function that, to most people, is basically magic. The wireless charging pad eliminates the fuss of power chords, while also allowing you to turn everyday furniture like tables and chairs into charging surfaces. Qualcomm **Runner up (Still Fantastic)** Our runner up was our previous winner, the [Panasonic RP-TCM 125 “Ergo Fit”](http://wrctr.co/tme1yaDpp4). They have a nice overall balance with airy, mellow highs and present but not dominating bass. They sound just as good listening to acoustic guitar as they do hip hop and rock. They don’t have the detail and depth of the Brainwavz, but for $14, they’re really great. The TCM-125 have a single-button remote and mic and come in a variety of colors, too. **Bass-Lover’s Alternate** Bass lovers should check out the [Sol Republic Jax](http://wrctr.co/tme1FxIW8x). While these headphones aren’t for everyone (or every kind of music), they are great for rock, pop, and hip-hop. Our resident bass-head adored them, and said that they were his personal favorite overall. The bass is intense, and can verge on the edge of sloppy in music that requires detail (so jazz, classical, and folk lovers will want to skip these) but if you like to rock, these kick ass. **Non-sealed in-ears (“earbuds”)** If you absolutely need non-sealed in-ears (i.e. “earbuds”) for more situational awareness, the best we could find were the [Sennheiser MX365](http://wrctr.co/tme1InSdDL). They sound better than the Apple EarPods, but they have scratchy foam pads and don’t sound anywhere near as good as our top picks. However, if non-sealed is something you need, the MX365 are your best bet. **Wrapping it up** Just because you don’t have a huge budget doesn’t mean you have to be satisfied with crappy sound. The [Brainwavz Delta](http://wrctr.co/1agSpGx) are more affordable than a new pair of Apple EarPods, sound better than anything else in this price range (including the EarPods), and can take calls and skip songs with the optional mic. Plus, at under $25, if they go missing, get chewed up by your dog, or get run through the laundry, you won’t cry yourself to sleep at night when you need to replace them. If you want to step up a bit in sound quality (and it is a _big_ step up), [check out our $100 in-ear picks](http://wrctr.co/1q1ncaZ). _This guide may have been updated.
