The Solidcom C1 Pro 4-Person Noise-Cancelling Headset Intercom from Hollyland is a dual-mic Environmental Noise Cancellation (ENC), full-duplex wireless DECT intercom system for use in loud environments and boasting all-day wearing comfort. It features a true-wireless design with no bodypack or hub required for operation.

The system comes with four dual-ear headsets (one master and three remotes), eight rechargeable batteries, an 8-bay charger, and various crucial accessories. The system transmits in the 1.9 GHz spectrum and employs proven DECT 6.0 technology to ensure secure and reliable two-way transmission at a line-of-sight range of up to 1100' with wide frequency response for clear audio. The package comes with a storage case for protection and transport of your gear.

Dual-Mic Environmental Noise Cancellation

For clear communication in loud environments, engage the dual-mic ENC (Environmental Noise Cancellation) feature. The ENC algorithm combines the main directional microphone at the speaker's mouth with a secondary omnidirectional environmental mic on the earcup to cancel out unwanted background noise for more intelligible speech. The microphone's wide 150 Hz to 7 kHz frequency response ensures detailed voice capture to keep your team working efficiently.

True-Wireless Self-Contained Headset for 2-Way Communication

With no beltpack needed, the C1 Pro offers a highly portable and hands-free coordinating experience for media production teams and others looking for real-time voice communication at line-of-sight distances up to 1100'. The Pro version offers increased portability and durability over the original, while the dual-ear headset design is dust and water resistant and designed to provide a comfortable all-day wearing experience.

Easy to Use

A long press on the A button on the master and remote headsets is all it takes; the headsets pair up in about 10 seconds and you're good to go. The microphone boom on each headset rotates 360°, allowing for left or right orientation. Rotating the boom arm up or down conveniently mutes the mic when not in use. Alternatively, the mute button on the earcup can be set to mute or push to talk, depending on the user's preference. An LED indicates the system is working and warns you when the battery is low.

Rechargeable Batteries

The master headset runs on a single rechargeable lithium-ion battery. The amount of battery time depends on the number of following headsets in use; with one to five remote headsets connected and the ENC features engaged, the battery will last for approximately five hours; with up to seven remote headsets in use, the battery life is four hours. Each battery fully recharges in approximately two and a half hours. Eight batteries are included in this system.

Expandable and Backwards Compatible

The Solidcom C1 Pro system allows you to link up to seven remote headsets (available separately) to the master headset without using a hub. The C1 Pro HUB Base (available separately) lets you use up to eight remote headsets at once. The C1 Pro master headset is backward-compatible with the Solidcom C1 system. Note that the ENC technology functions by removing the environmental noise at the speaker side.

Review of Crossway’s ESV Expository Commentary: Genesis–Numbers The Final Volume in a Landmark 12-Book Set Crossway’s release of the ESV Expository Commentary: Genesis–Numbers marks the long-awaited completion of their 12-volume expository commentary set ,a project that has served pastors, teachers, and lay readers with a rare blend of theological depth and pastoral warmth. This final installment offers rich insight into the foundational books of Scripture, bringing the story of God's redemptive plan into sharp focus right from the beginning. Theological Clarity Meets Pastoral Sensitivity Covering Genesis through Numbers, this volume tackles some of the Bible's most theologically significant and narratively complex material including creation, covenant, the patriarchs, the Exodus, and the wilderness wanderings. The contributors succeed in making ancient texts accessible, relevant, and worshipful without sacrificing exegetical rigor. Each passage is explained in context, showing how the Law and the beginnings of Israel's story point forward to Christ. Format and Usefulness True to the style of the series, this commentary is structured passage-by-passage, making it perfect for sermon preparation, Bible teaching, or devotional study. The tone is neither academic nor overly simplified—it’s pastoral, clear, and rooted in the authority of Scripture. The layout also includes helpful section summaries, theological insights, and practical application points. As always, all Scripture quotations are from the ESV, helping readers stay immersed in one translation. Series Finale Done Right As the first volume in biblical order but the last in publication, Genesis–Numbers fittingly brings the entire ESV Expository Commentary project full circle. It is a fitting capstone to a series that has been praised for its faithful interpretation, readability, and usefulness across denominations. Whether you're just beginning to explore the Bible or you're a seasoned preacher, this commentary and the series as a whole offers a trustworthy companion for growing deeper in God’s Word. Crossway has given the church a gift that will serve this generation and the next.

Nicely made and easy to read
Format: Hardcover
This arrived well packaged, but despite this, the two top corners of the book were somewhat smashed and there was more significant damage at the bottom of the spine where it was smashed. There is also some damage on the spine itself at about the level where Crossway is printed. The book appears well made and the paper is a good quality and thick. The print is of a nice size. One will most likely never access all the information enclosed in this commentary. In addition, one will most likely not agree with everything written, which should be expected of all commentaries. Commentaries are simply that and not authoritative. One hopes that by reading they might learn something new or be prompted to look more closely at a subject or issue. Let's look at Leviticus 11, for example, where the dietary guidelines are given to the Israelites. In the comments regarding pigs being forbidden, it is noted that the Philistines raised pigs for food. Knowing that, one can come to a conclusion that this may be why they were forbidden, so as to make a difference, or distinction, between the two peoples and not necessarily that pigs were bad to eat. In addition, throughout the commentary the reader is taken not just to other Old Testament passages, but where applicable the New Testament is referenced. Again using Leviticus 11, at the end of the chapter the commentary brings up the Jerusalem Council in Acts 15 when they issued the four requirements for Gentiles. It is noted that, "The Jerusalem Council agreed on four nonnegotiables to bring Jewish and Gentile believers to the same table, drawn in large measure from Leviticus's laws on holy living for the resident alien."

The Final Volume of An Excellent Commentary Series Does Not Disappoint
Format: Hardcover
After 7 years, Crossway has completed their ESV Expository Commentary set. Ironically, Vol. 1, was the last of the twelve volumes to be completed. It fully lives up to the standard the other eleven set. Like the other volumes, it focuses on a passage by passage commentary of each book, followed by a ‘Response’ section that is usually some form of practical application of belief or behavior. For example, in my copy, the ribbon marker was already in Exodus 17:1-7’s ‘Response’ page, and it discussed the question of ‘Why Does God Test His People?’. Jay Sklar’s response includes this wisdom: ‘testing not only gives us an opportunity to show faithfulness; it also helps us to to become more faithful.’ (pg. 578). While I have not yet read the whole thing, Crossway seems to have balanced some well-known scholars with other lesser known ones. Genesis in this volume is covered by Iain Duguid, noted OT scholar currently teaching at Westminster Seminary. Exodus is examined by Covenant Seminary Professor of Old Testament, Jay Sklar, who is a well-known expert on all five books of the Pentateuch. I had not heard of Christine Palmer (Leviticus) or Ronald Bergey (Numbers) before, but Crossway has earned my trust, and I presume their contributions will live up to the standards of others in this series. The commentary is pretty beefy, and the hardcover binding (if my previous volumes are any indication) will need to be handled with care - especially if you are like me, and sometimes try to photocopy pages so you don’t have to carry the whole commentary to a coffee shop or library! All in all, if you are a pastor, Bible student, or lead a Bible study, this series, and this volume, will be a benefit to you.

Excellent, Readable Bible Commentary
Format: Hardcover, Format: Hardcover
I feel more than a little inadequate writing a review of this first volume of the Expository Commentary which uses the English Standard Version (ESV) of the Holy Bible. The ESV has become my favorite Bible translation due to its excellent readability and reliability, thus influencing my decision to order this commentary. Just as readability influences my choice of Bible translations, this commentary also does an excellent job of maintaining readability across all four authors, each one having authored one complete book- Genesis through Numbers. This is a scholarly work and as such it uses references to a large body of additional scholarly works, more than three full pages worth, and lists abbreviations for each with those abbreviations noted throughout the text of the commentary for each book in the volume. These references include ancient as well as more contemporary works, most have English titles and a number are works grounded in the original Hebrew. Another help for any expositor are the ongoing references to other Bible passages that relate to the text of the commentary. Each of these references, and there are thousands of them, are listed in a Scripture Index organized from Genesis to Revelation that require nearly sixty pages at the very back of the volume. Though I’ve not read all 1392 pages, I’ve found editing to be excellent, though I did find one error on page 34 that had no consequence for understanding the meaning. I know many prefer the ease of using digital resources for study due to quick access, portability, and easy storage (I found this resource is also available digitally). I can easily recommend this resource without reservation.

Four Views on the Book of Revelation (Counterpoints: Bible and Theology) edited by Stanley N. Gundry and C. Marvin Pate I read this book after previously reviewing Revelation in Context: John’s Apocalypse and Second Temple Judaism. That book was helpful for me to understand Revelation as apocalyptic literature, one example of the genre with similarities to others from the first and second centuries. Interpreting Revelation as apocalyptic literature is itself a choice, and some approaches to Revelation, such as classic dispensationalism with its emphasis on grammatical-historical hermeneutics are skeptical of that approach. As Thomas writes in his chapter “To understand any passage of Scripture in a nonliteral way violates principles of grammatical-historical interpretation unless contextual features signal a need to interpret otherwise” (p. 244). I found Revelation in Context helpful for introducing various apocalyptic books of the age in providing greater context for Jewish thought up to and after John wrote Revelation. The editors of Four Views provide a good overview of the four views presented as well as a good introduction to Revelation. The four authors and their positions are: Kenneth L. Gentry, Jr. (preterist) Sam Hamstra, Jr. (idealist) C. Marvin Pate (progressive dispensationalist) Robert L. Thomas (classical dispensationalist) Each author made a case for his position and responded briefly to points by the other authors. Thomas is the most insistent in his argument and spends the most time critiquing the others’ positions. The differences stem entirely from their hermeneutics, each has a different approach to the book and each calls “foul” with the others’ misuse or lack of consistency of their own hermeneutics. For me, the winner was the preterist position, as I’d never truly been exposed to this paradigm. The author allows it to speak for itself, and I found it appealing because of how well the events of 68-70 AD as described (mainly) by Josephus line up eerily well with the words of Revelation. In some cases, it seems Josephus is quoting Revelation, which made me wonder whether the authors had taken liberties with the actual translation of Josephus’ works. After reading Gentry Jr.’s view, reading Revelation with a preterist’s viewpoint in mind made it a completely different book for me. Whether the position is correct or not, it allowed me to read Revelation again for the first time, so to speak– that was a gift. Thomas drove home for me that classical dispensationalism demands a special place for the ethnic people of Israel including a rebuilding of the temple along with its sacrifices. Babylon on the Euphrates is literally the Babylon of old and must also be rebuilt, which he interprets to be a Persian/Iranian empire that will come to fruition again. I think I can see how this view is at long last falling out of favor. Some of the writers may be somewhat heterodox. Gentry, for example, leaves open some possibilities for partial preterism or has some reasoning other preterists don’t have. Thomas is appalled at progressive dispensationalism’s “now and not yet” mentality as violating rules of grammatical-historical interpretation. Pate leaves the door open to Revelation having an earlier authorship and more sections being fulfilled in the first century than Thomas allows. Hamstra is in a field of his own, the “idealist” position sees Revelation as purely symbolic and not specific to any time period– everyone undergoing persecution is experiencing the spirit of the Antichrist, etc. Since reading this book, I’ve been checking out podcasts on preterism while pondering how covenantalists I know seem to sound like progressive dispensationalists. I am glad this book was published and will check out similar works in this series. Five stars.
