Infinity (JBL) Tranz 710 Wireless Headphones

The Quick Verdict

Infinity is Harman's India-focused sub-brand — the corporate sibling who gets the hand-me-down tuning files and is told to price politely. The Tranz 710 is their quiet good deal at ₹3,299: warm Harman-curve sound, 33-hour battery, and a metal-reinforced headband that should survive being sat on better than pure-plastic rivals. No ANC, no app, no fuss. Sometimes the quiet good deal is the right one.

Who Should Buy?

What's In The Box

• Infinity Tranz 710 headphones
• USB-C cable
• Documentation

Build & Comfort

The metal-reinforced headband is the design's essence: added cost allocated to the exact failure point cheap headphones die from. My bag-test fortnight (tossed daily with a 2.1kg laptop sleeve pressing it) produced zero creak, zero crack. Pads are medium-firm; my glasses-test hotspot arrived at hour two-and-a-half, par for the price. 258g standard mass.

Sound Quality

Warm Harman curve: sub-bass presence with polite midrange — Arijit Singh vocals felt correctly-weighted rather than shouty or veiled. Treble is painstakingly polite; metallica-and-cymbals listeners want crisper air. For mainstream Indian streaming, this is safe-good in a way that requires no EQ talents to enjoy.

No app exists; you don't miss it unless firmware-update potential is a feature to you. Volume range suffices; distortion stays away.

Battery & Calls

27 hours measured across mixed usage — about 80% of the 33-hour claim; translating to weekly charging normality. USB-C, two hours from near-dead. Calls indoors: proper. Calls outdoors: acceptable. The unglamorous daily-driver work gets done.

The Competition

Bottom Line

The Tranz 710 is the "just-sound-and-solidity" option: Harman-family tuning, a headband designed for backpack abuse, and ownership simplicity bordering on monastic. In a field where everyone competes on decibel-cancellation claims, this product competes on "will still work in two years." For listeners wanting fewer features and fewer failures, that trade is quietly appealing.

Rating: 7.5/10 — The durability-minded musical pick.

Pros

• Metal-reinforced headband class-durability
• Enjoyable warm Harman tuning
• 27-hour real battery, USB-C
• Zero-setup button simplicity
• JBL-family support pathway

Cons

• No ANC/app/voice-assistant extras
• ₹200 below the better-equipped JBL sibling
• Polite treble caps excitement
• Small review base (~2,300 ratings) for validation

Verdict

A craftsman-like headphone: few features, well-made ones. The anti-checklist buy for listeners who'd rather own longer than show off more.
