SonoFlow HQ51

The 1MORE SonoFlow Pro HQ51 delivers standout sound quality with LDAC support and a best-in-class 100-hour battery for $88. ANC is strong for the budget tier, but comfort is a serious weak spot, ranking in the 6th percentile of our database. Buy these if you want excellent value for short listening sessions. Skip them if you need all-day comfort.

Let's talk about what this thing does well first. The 40mm dynamic drivers paired with LDAC support put the sound quality in the 93rd percentile of our database. That's a standout result for an $88 headphone. LDAC means you're getting higher bitrate wireless audio from Android devices, and while it's not going to turn these into audiophile reference cans, the clarity and detail retrieval punch above what you'd expect at this price. The sound signature leans balanced with a slight emphasis on clarity rather than thumping bass, which is a refreshing change from the bass-heavy tuning most budget headphones default to.

The battery is the headline act. 100 hours of playtime puts these in the 98th percentile, which is basically best-in-class territory. For context, most competitors in this range land between 30 and 60 hours. The quick charge is also solid: 5 minutes gets you 10 hours. That's the kind of spec that changes how you use the headphones. You stop thinking about charging entirely. The ANC sits at the 81st percentile, which translates to strong performance for the price but not class-leading. It'll knock down airplane hum and office chatter effectively, but it won't match the silence you get from a Sony WH-1000XM4 or Bose QuietComfort. The dual-feed mic setup for calls lands at 64th percentile, which is about average. Fine for casual calls, not great for important meetings.

The most direct competitor here is the JBL Tune 670NC, which sits in a similar price bracket and offers comparable ANC performance. JBL's build quality tends to be more consistent, and their comfort is generally better, but you're giving up LDAC and the absurd battery life. The TOZO HT3 is another budget darling that undercuts the SonoFlow Pro on price and offers surprisingly good ANC for the money, but the sound quality doesn't match what 1MORE is doing with LDAC. If sound is your priority, the 1MORE wins. If comfort matters more, the JBL is the safer bet.

Stepping up in price, the Sony WH-1000XM4 and Sennheiser MOMENTUM 4 are in a different league entirely. Better ANC, better comfort, better build, better call quality. The Sennheiser also has a 60-hour battery, which is excellent but still well short of 100 hours. The Beyerdynamic Aventho is aimed at a more audiophile crowd with a focus on wired listening quality. If you can stretch your budget to $200+, any of those three will be a more well-rounded purchase. But if you're locked into the sub-$100 range, the SonoFlow Pro's combination of LDAC and battery life is hard to beat on paper.

At $88 USD, the SonoFlow Pro is aggressively priced for what it offers. You're getting LDAC, 100-hour battery, and solid ANC in a package that undercuts most name-brand competitors by $50 to $100. The value proposition is strong enough that our budget score comes in at 60.5 out of 100, which is respectable. The CAD price of $133 and EUR price of 208 are less compelling, and at those prices the calculus shifts. In Europe especially, you're getting close to Sony WH-1000XM4 territory on sale, and that's a much better headphone overall.

The real question is whether the comfort issue undermines the value. A headphone you can't wear for more than an hour or two isn't a great deal no matter how cheap it is. If your use case is short commutes, gym sessions, or quick listening bursts, the comfort won't matter much and the value is excellent. If you're planning to wear these all day at a desk or on long flights, the math gets murkier.

The 1MORE SonoFlow Pro HQ51 lands in one of the most crowded spaces in audio right now: budget wireless ANC headphones. You can throw a rock on Amazon and hit a dozen pairs promising noise cancellation, long battery life, and decent sound for under $100. So when a pair shows up with a 100-hour battery claim and LDAC support at this price, it's worth paying attention. We've seen the spec sheet, run the numbers, and dug through what actual buyers are saying. The short version: this is a value play that mostly delivers, with one glaring comfort issue that might be a dealbreaker for some.

Who's this for? Someone who wants a travel or office headphone that can go weeks between charges, doesn't want to spend Sony or Bose money, and cares more about sound quality than call quality. The LDAC support is genuinely unusual at this price point, and the ANC performance sits well above average for the budget tier. If you're coming from cheap wired earbuds or an aging pair of Bluetooth cans, the jump here will feel significant.

The interesting tension with the SonoFlow Pro is that it nails the headline features, battery and sound, while struggling with the thing you notice most after hour two: comfort. Our database puts comfort in the 6th percentile, which is rough. That's the kind of number that makes you wonder if the 100-hour battery is a promise or a threat. More on that below.

If you need headphones for all-day wear, skip these. The comfort ranking in the 6th percentile isn't just a stat, it's a real problem that multiple owners have confirmed. Ear cushion discomfort sets in after extended use, and that's a dealbreaker for office workers, students, or anyone who wants to wear headphones for 4+ hours straight. Look at the JBL Tune 670NC for better comfort in the same price range, or stretch to the Sony WH-1000XM4 if you can.

Also skip these if call quality is a priority. The mic performance lands at the 64th percentile, which is about average, and the transparency mode has an occlusion effect that makes your own voice sound strange during calls. If you're on Zoom meetings all day, these aren't the right tool. The Sony WH-1000XM4 or even the Sennheiser MOMENTUM 4 will serve you much better for voice calls, though you'll pay more for the privilege.

For short-session listeners on a budget, the SonoFlow Pro is an easy recommendation. The sound quality with LDAC is genuinely impressive for the price, the ANC is better than most budget options, and the battery life means you'll forget where the charger is. If you're using these for commutes, workouts, or casual listening in hour-long chunks, you'll be very happy. The included hard case is a nice bonus for travel.

For all-day users, the comfort issue is a real problem. The 6th percentile comfort ranking isn't just a number, it's backed up by multiple owners reporting ear cushion discomfort during extended wear. If you work in an office and want something you can wear for 4+ hours straight, these will likely start to hurt. In that case, spend a bit more on the JBL Tune 670NC or save up for a Sony WH-1000XM4. The SonoFlow Pro is a great headphone for the right use case, but it's not a one-size-fits-all solution.
