Danny Winget

@dannywinget
Tech Reviewer & Content Creator

Danny Winget’s days are filled with late-night filming, constant research, travel, and back-to-back briefings. After nearly a month with Halliday G2, he found practical uses for its glanceable notifications, presentation notes, and open-ear audio within that routine. Meeting Flow stood out for helping him revisit important discussions and follow-ups, reducing the pressure to capture every detail while listening.

Nathan Espinoza

@nathanespinozayt
Tech Content Creator

Nathan Espinoza was drawn to the contrast between Halliday G2’s ordinary appearance and the information available inside. He highlights being able to check notifications without picking up his phone and access conversation assistance in settings ranging from lectures to everyday chats. His most personal demonstration comes at the end: he reveals that he has been reading his script through the glasses throughout the video.

Justin Tse

@JustinTse
Content Creator, Founder & CEO of Feature Media

Justin Tse approaches Halliday G2 from the perspective of a creator and business owner moving between focused work and team discussions. He explores how information in view can help him follow fast-moving conversations, understand unfamiliar terms, and review decisions afterward. Outside those discussions, he appreciates being able to listen to music and access quick AI answers through glasses he finds comfortable and natural to wear.

Joshua Vergara

@jvtechtea
Tech Reviewer & Host

Joshua Vergara finds himself turning to Halliday G2 for small questions more often than he expected, from currency conversions to calculating the weight of ingredients while cooking. In conversations with his partner, he also uses it to revisit details such as what they had agreed to eat for dinner. For him, the value comes from having useful backup close at hand, across both work and everyday life.

Ben Sin

@bensgadgetreviews
Tech Journalist & Reviewer

Ben Sin’s experience with Halliday G2 takes him to a product launch in Germany, where technical information, casual conversation, and multiple languages overlap. He describes using captions, translation, and contextual research to follow those exchanges, then checking the transcript and summary afterward. As a reviewer who regularly attends briefings, he values having a record to return to when there is too much information to remember at once.

Dimitris Maintas

@edc_tech_
Content Creator, Photographer & Videographer

For @edc_tech_, Halliday G2’s appeal is having useful AI assistance within a pair of glasses that still looks and feels familiar. He highlights a display that keeps information readable without dominating his view, alongside access to translation and conversation support. His perspective centers on practical help: keeping decisions and follow-ups accessible while avoiding the bulk he associates with wearable technology.

TechUtopia

@techutopiareviews
Tech & Gadget Reviewer

@techutopiareviews approaches Halliday G2 through the challenge of remembering names, deadlines, and tasks while staying engaged in a discussion. He values the glanceable display for keeping useful information accessible, with conversation assistance and summaries providing additional support. His takeaway extends to presentations, calls, and everyday questions, where the glasses can reduce the need to keep switching back to a phone.

Steven Sullivan

@StevenSSullivan
Smart Glasses Reviewer & Content Creator

Steven Sullivan tests Halliday G2 while chatting with his partner about films, actors, and their plans for the day. Quick Research becomes a particular highlight for him because he can choose when to look up something being discussed, then return to the conversation with more context. He also uses Cheatsheet while recording his review, giving him firsthand experience of keeping presentation notes in view.

Tomas Milinavicius

@tomas.milinavicius
Photographer & Content Creator

@tomas.milinavicius starts with a habit he recognizes in himself: checking his phone too many times throughout the day. Halliday G2 gives him another way to access messages, schedules, and translation without repeatedly reaching for that screen. For his own filming, Cheatsheet keeps his prepared script in view, and he reveals that he used it to deliver this very video.

Zachary Charles

@thejunglebadger
Product Reviewer & Content Creator

@thejunglebadger sees Halliday G2 as useful backup when a busy conversation becomes difficult to keep track of. He focuses on accessing conversation context, tracking commitments, and finding notes and action points on his phone after a call. Alongside that support, he appreciates the sleek, camera-free design and the convenience of having translation and music in the same pair of glasses.

Eliot

@techdropp
Tech Reviewer & Content Creator

For @techdropp, the interesting part of Halliday G2 is how much conversation support sits behind its ordinary-looking design. He highlights tools for checking recent discussion points, researching unfamiliar information, and identifying commitments that still need an owner or deadline. The value he presents continues after the conversation, with a summary that brings the important details together.

Andrea Mosca

@iandreamosca
Content Creator & Videographer

@iandreamosca approaches Halliday G2 with a question about his everyday routine: how much less could he rely on reaching for his iPhone? He explores keeping notifications, calendar information, weather, and AI answers in view, with built-in speakers handling music and calls. For him, the appeal is bringing several small, frequently used tools together in something he can wear.

FAQs

The Translation and Meeting Flow function on the G2 is compatible with more than 45 languages, including English, Chinese, Japanese, and Korean, among others. Please refer to the full language list here: Language-Support.

The glasses system and Halliday app only support English in the current version. We are actively working to support more languages in future updates.

No. Halliday G2 does not have a built-in camera. We designed them this way to focus on a more comfortable, privacy-friendly, and all-day wearable experience. A camera-free design helps keep the glasses lightweight, supports longer battery life, and allows you to use them more naturally in everyday situations without concerns about recording or privacy.

Halliday G2 supports single-vision prescription lenses with a sphere (SPH) range of -10.00 to +2.00 and a cylinder (CYL) range of -4.00 to +4.00, both in 0.25 D increments. The supported ranges vary by lens index: • 1.60 Index: SPH from -6.00 to +2.00; CYL from -2.00 to +2.00. • 1.67 Index: SPH from -9.00 to +2.00; CYL from -3.00 to +3.00. • 1.74 Index: SPH from -10.00 to +2.00; CYL from -4.00 to +4.00. The supported pupillary distance (PD) ranges are: • Total PD: 56–74 mm • Monocular PD: 30–50 mm per eye Important: Each eye must meet both the SPH and CYL limits for the selected lens index. Additionally, the sum of SPH and CYL, calculated using their positive or negative signs, must not exceed +2.00 for either eye.

Halliday G2 Glasses integrates multiple large language models simultaneously to meet the demands of various scenarios.
